The present invention advantageously provides a simple method and associated system capable of automating voice activated device enabling.
System 100 enables a historical learning process with respect to a command sequence for same or different (voice activated) devices. The devices are configured to extract appropriate keyword and/or phrases from any submitted voice command. Likewise, the devices may be configured to dynamically set an alternate wakeup command for one or more devices such that a user is not required to submit a fixed wakeup command every time a device activation is necessary.
System 100 of
System 100 is enabled to execute a process for enabling a voice activated device as follows:
System 100 is configured to contextually classify a voice activated instruction set retrieved with respect to differing time steps for various voice enabled or Internet of Things (IoT) devices controlled by a voice enabled software/hardware coordinator. The classification process is enabled by allowing instructions to flow through staged sequence models to enable devices to wake up without usage of wakeup keywords presented each time an instruction is fired. Likewise, it is not necessary to determine a device for receiving a current instruction set. Staged sequence models may include a trigger word detection model for constantly detecting a defined trigger word for each device. Additionally, staged sequence models may include a trigger word detection model for providing an instruction classified by the staged sequence model to be applied to a specified device thereby eliminating a need for a continuous a trigger word.
A staged sequence model may be trained with respect to a start keyword to recognize as an instruction to differentiate between commonly spoken words and an instruction set. The start keyword is different from a trigger word and is not configured to wake up any device. Likewise, the start keyword is configured to classify a sentence as an instruction set intended for device activation.
If sequence model probabilities do not specify a clear difference between devices, then a current instruction set and an immediate previous instruction set is fed into a BERT model to identify if the current instruction set comprises a next instruction set. The BERT model may be different for each device. Alternatively, the BERT model may be the same for each device and comprise two outputs: a first output may be associated with an intended device and a second output associated with a binary classifier to indicate that both sentences are in sequence.
If there is no previous instruction set, then an associated ambiguity may be clarified with the user via specific questions related to a device associated with instructions and a last stage of a model.
A transfer learning process may be enabled for all models with each stage of a model pre-trained with a generic instruction set associated with the system learning about devices within a closed environment with respect to user-device interaction processes. Initially there may exist ambiguity questions for users, but when the system executes a self-learning process, an output may be generated to awaken a specific device within earlier stages of the model itself.
In step 202, it is determined (in response to results of the analysis of step 200) that specified instruction keywords are located within the initialization commands. In step 204, the initialization commands are inputted into a bidirectional encoder representations from transformers (BERT) model classifier component. In step 208, at least one specified device associated with the instruction set is classified execution of the BERT model classifier component. Classifying the at least one specified device may include: executing a set of instructions and (in response) generating an output defining a probability associated with a corresponding device with respect to the set of instructions.
In step 210, it is determined (based on a probability output from the BERT model classifier component) if a maximum threshold is reached for any class of devices. Results of the determination may indicate that the maximum threshold is reached for any class of devices and a voice controlled assistant may acknowledge the instruction set. In response, a trigger signal for enabling the at least one specified device may be generated. Alternatively, results of the determination may indicate that the maximum threshold is not reached for any class of devices and a voice controlled assistant may acknowledge the instruction set such that a context request for the user with respect to the instruction set is initiated.
In step 212, the at least one specified device is assigned as at least one desired device in response to results of step 210. The assigning process may include predicting a corresponding class related to a previous context of the instruction set. Alternatively, the assigning process may include initiating a user request for retrieving information associated with a user selected device associated with the instruction set.
In step 214, the at least one specified device is enabled with respect to an operationally functional state in response to at least one instruction keyword of the instruction keywords and results of the assigning of step 212. The at least one specified device may include a first device and a second device. The first device may be maintained with respect to the operationally functional state in response to a second instruction keyword of the instruction keywords. Likewise, the second device may be disabled with respect to the operationally functional state in response to the second instruction keyword.
System 400 is configured to analyze a context of a voice command to trigger a respective smart device as described in the following example process scenario:
The process is initiated when user 402 speaks the term “Now” and in response, none of devices 408 (i.e., devices 408a, 408b, and 408c) will awake (i.e., become enabled for operation). When user 402 speaks the term “now set” device 408a (i.e., a washing machine) and device 408c (i.e., a microwave oven) will awake such that they are enabled for operation. When user 402 speaks the term “now set temperature” device 408a will go to sleep (i.e., become operationally disabled) and 408c will awake. Likewise, dynamic and situational commands may be advantageously utilized system 400 to trigger any of devices 408 instead of fixed wakeup command for each of devices 408. For example, conventional user 402 commands are given as follows:
1. Washing Machine (device 408a) please set mode 4 such that the washing Machine is triggered for operation.
2. Coffee machine (device 408b) prepare a cup of coffee such that the coffee machine is triggered for operation.
3. Microwave oven (device 408c) set the temperature to 180 degree such that the microwave over is triggered for operation.
System 400 is configured to identify that a respective smart device (of devices 408) must be triggered as soon as it analyzes the context of a command. Likewise, attention is given to an alternate wakeup command based on a contextual situation and predicted next command as follows:
A command: Please set mode 4 triggers (for operational functionality) device 408a (after analyzing command context).
A command: Prepare a cup of coffee triggers (for operational functionality) device 408b (after analyzing command context).
A command: Set the temperature to 180 degree Celsius triggers (for operational functionality) device 408c (after analyzing command context).
A process associated with a first time step 507 is executed as follows:
In step 508, user 501 does initiate any trigger word. Likewise, user 501 speaks an actual instruction comprising a start word that does not explicitly say which smart device the command refers to. In step 509, it is determined if the start word or instruction keyword is available within the input command from user 501. If the instruction keyword is detected as available within the input command, then in step 510, the command is transferred to a BERT model classifier component. If the instruction keyword is not detected as available within the input command, then in step 511, the user request is ignored as it is considered as background noise.
In step 512 (i.e., a first stage of the model) the BERT classifier component classifies and associates specified instructions for each device. The classification is performed based on generic learning within a generic set of instructions and reinforcement learning associated with a particular context. A resulting output provides a probability of a device corresponding to an inputted instruction set.
In step 514, it is determined if a maximum threshold has been reached for any class based on a probability output from the BERT classifier. If a maximum threshold has been reached for any class in the BERT classifier output, then in step 523, a voice controlled assistant acknowledges the request and triggers a corresponding smart device. If a maximum threshold has not been reached for any class in the BERT classifier output, then in step 516, the voice controlled assistant requests that user 501 verify context. For example, if there is a low confidence level between two or more devices, then step 518 determines a path 519 or a path 521.
Path 519 enables a classifier module for determining if historical context is available for tuning a probability towards a desired device. If any historical context is detected as previously available, then the model is configured to predict a corresponding class related to previous context and it increases a probability for that class.
If there is no clear historical context available previously, then path 521 is configured to request that user 501 specify a device for which the instruction is intended for.
Subsequently, a final output is predicted by the model as a respective device based on context and a corresponding device is triggered.
A process associated with a second time step 534 is executed as follows:
A portion of the model associated with second time step 534 is configured to specify that any instruction without a keyword is dis-regarded as generic conversation. The keyword may be common for all devices in a home or office environment. Second time step 534 is associated with a layer for avoiding voice enabled devices processing generic texts that are spoken but not intended for device activation.
A process associated with a third time step 538 is executed as follows:
A portion of the model associated with third time step 538 is configured to correctly classify (when there is an instruction to an alternative device such as a washing machine.) that the instruction is for a new device even through another device is already running and executing a previous instruction.
A process associated with a fourth time step 540 is executed as follows:
A portion of the model associated with fourth time step 540 is configured to allocate a new instruction without a trigger word and association with an intended device. The allocation is analyzed contextually with instructions already fed into other devices using BERT model trained with respect to a next sentence classifier for predicting if a current instruction comprises a continuation from a previous instruction such that a corresponding device is activated.

While
It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.
Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.
Characteristics are as follows:
On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.
Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).
Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.
Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.
Service Models are as follows:
Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.
Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).
Deployment Models are as follows:
Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.
Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.
Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.
Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).
A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.
