Patent Application
20230232173
The present subject matter relates to the hearing assistance device user interface for processing and control, and in particular using additional computing resources for analysis.
Hearing devices provide sound for the wearer. Examples of hearing devices include headsets, hearing assistance devices, speakers, cochlear implants, bone conduction devices, and personal listening devices. Hearing assistance devices provide amplification to compensate for hearing loss by transmitting amplified sounds to their ear canals. In various examples, a hearing assistance devices is worn in or around a patient's ear.
Hearing assistance devices often have limited processing power, memory, and other computing resources. Due to these limited resources, hearing assistance devices sometimes lack the ability to directly implement resource-intensive operations. Hearing assistance devices typically include digital electronics to enhance the wearer's experience. This enhanced functionality is further benefited from communications, such as from a mobile device or a remote source for advanced processing.
Disclosed herein, among other things, are systems and methods for remote analysis of an acoustic environment to be used in a hearing assistance device. Specifically, a system can include a hearing assistance device, a mobile device, and a remote server. The mobile device can capture an acoustic environmental and send information about the environment to a remote server. The remote server can search for similar acoustic feature sets and associated hearing assistance parameters. The hearing assistance parameters can be sent to the mobile device for selection by a user or parameters can be sent to the hearing assistance device (e.g., via the mobile device).
This Summary is an overview of some of the teachings of the present application and not intended to be an exclusive or exhaustive treatment of the present subject matter. Further details about the present subject matter are found in the detailed description and appended claims. The scope of the present invention is defined by the appended claims and their legal equivalents.
The following detailed description of the present subject matter refers to subject matter in the accompanying drawings which show, by way of illustration, specific aspects and embodiments in which the present subject matter can be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the present subject matter. References to “an”, “one”, or “various” embodiments in this disclosure are not necessarily to the same embodiment, and such references contemplate more than one embodiment. The following detailed description is demonstrative and not to be taken in a limiting sense. The scope of the present subject matter is defined by the appended claims, along with the full scope of legal equivalents to which such claims are entitled.
In an example, an acoustic environment analysis can be conducted. The analysis can be conducted in order to provide different acoustic environment processing in different environments, for example, based on user preference, user comfort with changes in processing in different environments, or in order to provide processing that is useful in some specific environments but can be detrimental in other environments. For example, in systems that can determine that a user of a hearing assistance device is sitting in a church or an opera, the systems can provide a user interface for adjusting the hearing assistance device. Adjustments to parameters of the hearing assistance device can be made by the user of the hearing assistance device (so-called self-adjusting, as opposed to adjustments made by an audiologist or fitting professional) using the user interface. The user interface can be specific to the listening environment (e.g., church, opera, etc.).
Hearings assistance devices are able to perform only limited acoustic environment analysis due to processing and memory constraints. Additional computing resources such as mobile devices and cloud computing can greatly expand the possibilities for improving environment classification and adaptation, and subsequent hearing aid adjustment. In an example, improving classification and adaptation can include aspects beyond the acoustic environment, such as adaptation to a listening situation identified non-acoustically. For example, in systems that can determine from non-acoustic information, such as global positioning system (GPS) data or accelerometer data, that a user of a hearing assistance device is traveling in a car or airplane, the systems can provide a user interface for adjusting the hearing assistance device. The user interface can be specific to the situation (e.g., car, airplane, etc.). In an example, the non-acoustic identification can include data related to the user of the hearing assistance device (e.g., audiometric thresholds) or about the state of the user (e.g., bio-sensor data, such as galvanic skin response data). Acoustic data can be combined or used in conjunction with non-acoustic data.
Machine learning techniques, represent one class of algorithms that operate either on the mobile device, or on a computing server in the cloud, or both, to respond to data provided from the user's mobile device (or hearing aids).
In addition, combining, in some fashion, data collected from a large number of users is one potential way that the server in the cloud can add capability that is unavailable with the mobile device alone. Machine learning algorithms are useful tools for (among other things) processing and learning from very large volumes of data.
In an example, using computing resources remote to the hearing assistance device can improve hearing assistance device adjustments by performing an acoustic scene analysis on the remote computing resources. Remote computing resources can be provided by a mobile device, or some other wirelessly connected device in the vicinity of the user, or by a computer or server in the cloud, connected to the user's mobile device by a network. The remote computing resources can have significantly greater processing power than the hearing assistance device, and can use computationally demanding data analysis algorithms, and can incorporate additional data not available locally. In an example, additional data can be drawn from a history of the user's activities and interactions, or from a history of many users' activities and interactions.
Remote computing resources can provide hearing assistance device users a better performing hearing assistance device by using acoustic scene analysis to configure a graphical interface for self-adjusting. In an example, the remote computing resources can expand or replace the self-adjusting (adjustments made by a wearer of a hearing assistance device) done in the hearing assistance device, using a graphical interface operating on the mobile device. In an example, a hearing assistance device system with computing resources remote to the hearing assistance device can adapt and improve by learning over time using a growing database.
In another example, the mobile device 104 can be used to send acoustic environment information to the server 108, via the network 106, and the server 108 can process the acoustic environment information and send parameters back to the mobile device 104 for implementation by the hearing assistance device 102.
The mobile device 104 or the server 108 can save previously selected parameters for a user. The mobile device 104 can include an internal microphone, an external microphone, or can connect to a microphone remotely. The hearing assistance device 102 can capture the acoustic environment and send information about the acoustic environment to the mobile device 104, such as by using a wireless connection.
In an example, a database 110 can be accessed by any of the devices including the mobile device 104. In another example, the server 108 can include the database 110. The database 110 can include one or more databases on one or more servers or computers. In an example, acoustic analysis data (e.g., measurements or features), can come from a single user, or from many users, or the data can include information distilled from multiple submitted sets of acoustic analysis data (e.g., measurements or features), non-acoustic data, or both. In addition, the data can contain hearing assistance parameters or user interface configuration information associated with the acoustic environments or features.
A machine learning system, such as an artificial neural network, can be used to implement or support the learning from aggregated data, for example from a plurality of users, or in another example, from a single user. As the database grows, the neural network can be retrained (or further trained) to improve its accuracy, and the quality of the returned results. The neural network training can be performed on the server 108, or it can be performed on the mobile device 104, including with additional optional data (e.g., data from multiple users) supplied from the server 108. The online operation of the neural network can be performed on the server 108 or on the mobile device 104, or on the hearing assistance device 102. The neural network can also be trained and downloaded from the server 108.
Neural networks are used to learn automatically the relationship between data available in the online operation and a desired system response or output. In this case, the network learns (during the training phase) the relationship between input data (for example, acoustic features) and desired outputs (for example, a configuration of the self-adjustment UI).
Neural network-based processing generalizes and infers the optimal relationship between input data and desired output from a large number of examples, referred to as a training set. Elements of the training set comprise an example of network input and the desired target network output. During the training process, which can be performed offline, the network configuration is adapted gradually to optimize its ability to correctly predict the target output for each input in the training set. Given the training set, the network learns to extract the salient features from the input data, those that best predict the desired output, and to optimally and efficiently combine those features to produce the desired output from the input. During a training phase, example system inputs are provided to the algorithm along with corresponding desired outputs, and over many such input-output pairs, the learning algorithms adapt their internal states to improve their ability to predict the output that should be produced for a given input. For a well-chosen training set, the algorithm will learn to predict outputs for inputs that are not part of the training set. This contrasts with traditional signal processing methods, in which an algorithm designer has to know and specify a priori the relationship between input features and desired outputs. Most of the computational burden in machine learning algorithms (of which neural networks are an example) is loaded on the training phase. The process of adapting the internal state of a neural network from individual training examples is not costly, but for effective learning, very large training sets are required. In various embodiments, learning takes place during an offline training phase, which is done in product development or research, but not in the field.
In certain embodiments, the neural network training, or some part of it, can be performed online. For example, based on data collected from the hearing aid wearer's experience, the neural network can be retrained (or refined through additional training) on a smart phone, which can then download the updated network weights and/or configuration to the hearing aid. Based on data collected from a group of hearing aid wearers' experiences, such as collected on a server in the cloud, the neural network can be retrained in the cloud, connected through the mobile device, which can then download the updated network weights and/or configuration to the hearing aid in further embodiments. In further embodiments, the neural network is retrained in the cloud and the updated network weights or configuration are applied in the mobile device.
Data used to train the neural network can come from adjustments made by hearing assistance device wearers, using a User Interface (UI), or using some other mechanism (such as volume control), or they can come from other information solicited from the hearing assistance device wearer, or from other non-interactive components (including, for example, geolocation information obtained from the mobile device, or navigation data). Data can be acoustic or non-acoustic. The non-acoustic data can represent an acoustic environment, or can represent characteristics of a hearing assistance device wearer (such as a user's audiogram, or data from a biosensor or biosensors).
The results produced by the network can be used to configure a UI, (as described above), or to present some other adjustment mechanism to the hearing assistance device user, or to control or configure the hearing assistance device directly through the mobile device. A hearing assistance device as described herein can include a pair of hearing assistance devices, a set of hearing assistance devices, etc., or an individual hearing assistance device. In cases of multiple hearing assistance devices, parameters can be determined for each hearing assistance device individually, pairs or sets of hearing assistance devices, or all of the multiple hearing assistance devices at once. In various embodiments, other supervised machine learning algorithms can be employed in place of neural networks.
The systems and methods described herein can provide a situation-specific self-adjustment tool on a mobile device, and use remote computing resources (e.g., on the mobile device or in the cloud/at a server) to determine how that tool should change according to an acoustic environment or listening situation. In an example using a server, data from multiple users can be used by the system to learn over time, through use, how to recommend or provide a self-adjustment tool appropriate to the user's immediate listening environment or listening situation. The systems and methods described herein can greatly reduce time required to adjust the hearing assistance device for a user in response to changing listening environments. The systems and methods can eliminate the need of the user to return to a hearing professional for adjustments which increases the likelihood of hearing assistance devices being accepted and used.
The user interface 302 can be used to display or represent the set of hearing assistance parameters, for example, in a pre-defined space on the user interface 302. The processor 308 can be used to run an app on the mobile device 300. The app can be used to display or represent the set of hearing assistance parameters on the user interface 302, such as in the pre-defined space. The user interface 302 can be used to receive a selection, such as a user selection in the pre-defined space (e.g., a touch input or gesture input), of a hearing assistance parameter of the set of hearing assistance parameters. The user selection can be a user input on the user interface 302 that does not appear to be a selection of the hearing assistance parameter, but instead an intuitive graphical selection of an option that sounds the best to the user. The selection can include a selection of a hearing assistance parameter from the set of hearing assistance parameters that sounds best to the user. In another example, determining the selection can include interpolating among hearing assistance parameters to obtain a parameter or parameter change.
In an example, the processor 308 can be used to prepare for output, the hearing assistance parameter selected by the user on the user interface 302. In an example, the transceiver 306 can be used to send the selected hearing assistance parameter to a hearing assistance device. The hearing assistance device can be communicatively coupled to the mobile device 300. For example, the transceiver 306 can send the hearing assistance parameter to the hearing assistance device using Bluetooth, Wi-Fi, near field communication, or the like.
The technique 500 includes an operation 508 to receive a selection on a user interface of the mobile device, the selection including hearing assistance parameter information. The hearing assistance parameter information can include a parameter or a parameter change. The hearing assistance parameter information can include information from the information for use in the user interface from operation 506. The selection can be made by selecting a visual context coordinate or set of coordinates from the visual context coordinates corresponding to the set of hearing assistance parameters. The technique 500 includes an operation 510 to send the selected hearing assistance parameter information to a hearing assistance device or to program the hearing assistance device with the hearing assistance parameter information. For example, operation 510 can include sending a parameter or a parameter change selected in operation 508 to the hearing assistance device.
The technique 500 can include an optional operation 512 to send the selected hearing assistance parameter information to the remote server for integration into a database. The selection can be used in a machine learning technique to improve selection of future sets of hearing assistance parameters or to improve future hearing assistance parameters themselves.
The technique 600 includes an operation 606 to send the information for use in a user interface of the mobile device to the mobile device. Operation 606 can include sending visual context coordinates, a set of hearing assistance parameter information, hearing assistance parameter changes, or the like to the mobile device. The technique 600 includes an operation 608 to receive selected hearing assistance parameter information from the mobile device. For example, the selected hearing assistance parameter information can include a parameter, a parameter change, a visual context coordinate or change, a location from the user interface, or the like. The selected hearing assistance parameter information can be from the information sent in operation 606.
The technique 600 can include an optional operation 610 to use machine learning techniques to improve future hearing assistance parameters by incorporating the selection of the selected hearing assistance parameter information, such as into a database. The incorporation can include assigning a weight to the selected hearing assistance parameter information. For example, selections of hearing assistance parameters or changes to the parameters can be given a higher weight than hearing assistance parameters or optional changes that are not selected, less frequently selected, or unselected for a period of time. The machine learning techniques can include techniques to weight hearing assistance parameters or changes, to classify acoustic feature vectors to corresponding hearing assistance parameters or changes, or to determine or assign sets of hearing assistance parameters or changes.
Remote analysis of an acoustic environment can be use in a hearing assistance device according to an example. A mobile device, such as a smart phone can include one or more auxiliary microphones connected to the mobile device, built in, connected, or remote to the mobile device (e.g., a built in microphone, a connected or remote computer microphone, a connected or remote watch, a remote hearing assistance device, etc.). In an example, an operation can include using a microphone to sample or record the current acoustic environment and the mobile device or a remote device to analyze acoustic environment in response to user initialization. In another example, the analysis of the sample (e.g., a recording) can be performed on a hearing aid, on a mobile device, or on a remote computer. The mobile device can perform an initial pre-processing, such as a feature extraction. The acoustic environment data (e.g., a sample recording, measurements of a recording, or features of a recording) can be sent to a remote system at another operation. The remote system can include a server, desktop computer, laptop computer, tablet, other mobile device, etc.
An operation can include performing further processing, such as feature extraction or environment classification at the remote system. In an example, the environment classification can incorporate machine learning techniques to determine an optimal set of potential hearing assistance device settings for the user. In another example, the environment classification can incorporate machine learning techniques to determine the configuration of a user interface for self-adjustment of the hearing assistance device settings. The parameters can be returned the to the mobile device. An updated set of constraints or a configuration for a graphical interface can be sent to the mobile device for use on the mobile device, that allows the user to navigate in a pre-defined space to actively modify the hearing assistance device settings as the user moves around the screen. In another example, a user interface can receive a user input to actively modify the hearing assistance device settings. When the user is comfortable with the hearing assistance device performance, the user can save preferred settings as a new hearing assistance device memory to be accessed easily. The navigated settings chosen by the user can be sent back to the server for integration and learning.
Examples, as described herein, can include, or can operate on, logic or a number of components, modules, or mechanisms. Modules are tangible entities (e.g., hardware) capable of performing specified operations when operating. A module includes hardware. In an example, the hardware can be specifically configured to carry out a specific operation (e.g., hardwired). In an example, the hardware can include configurable execution units (e.g., transistors, circuits, etc.) and a computer readable medium containing instructions, where the instructions configure the execution units to carry out a specific operation when in operation. The configuring can occur under the direction of the executions units or a loading mechanism. Accordingly, the execution units are communicatively coupled to the computer readable medium when the device is operating. In this example, the execution units can be a member of more than one module. For example, under operation, the execution units can be configured by a first set of instructions to implement a first module at one point in time and reconfigured by a second set of instructions to implement a second module.

The instructions 824 can also reside, completely or at least partially, within the main memory 804, within static memory 806, or within the hardware processor 802 during execution thereof by the machine 800. In an example, one or any combination of the hardware processor 802, the main memory 804, the static memory 806, or the storage device 816 can constitute machine readable media.
