Embodiments of the invention relate to voice focus enabled by predetermined triggers. In certain embodiments, the voice recognition enabled by predetermined triggers is implemented in a hearing aid.
For those who wear hearing aids, it can be difficult to distinguish a conversation in a crowd or in a situation that has a high amount of background noise. This is known as the “cocktail party effect”.
Having a discussion or conversation in a crowded room or in a situation in which there is ambient noise may result in the speaker having to shout, and the person wearing the hearing aid to cup their ear and “point” their ear towards the speaker to help isolate the conversation. Another solution is to increase the volume of the hearing aid, which may contribute to increased hearing loss. Moreover, yet another existing solution uses keywords to position microphones in hearing aids toward the speaker for better clarity.
Provided is a method for voice focus enabled by predetermined triggers. The method comprises using, with a processor of a computer, voice recognition to identify one or more pre-determined triggers from a voice of a speaker; and, in response to identifying the one or more pre-determined triggers, dynamically creating a voice recognition template for the voice of the speaker, and using the voice recognition template and voice isolation to focus on the voice from the speaker.
Provided is a system for voice focus enabled by predetermined triggers. The computer system comprises: one or more processors, one or more computer-readable memories and one or more computer-readable, tangible storage devices; and program instructions, stored on at least one of the one or more computer-readable, tangible storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, to perform: using voice recognition to identify one or more predetermined triggers from a voice of a speaker; and, in response to identifying the one or more pre-determined triggers, dynamically creating a voice recognition template for the voice of the speaker, and using the voice recognition template and voice isolation to focus on the voice from the speaker.
Provided is a computer program product for voice focus enabled by predetermined triggers. The computer program product comprises a computer readable storage medium having program code embodied therewith, the program code executable by at least one processor to perform: using, by the at least one processor, voice recognition to identify one or more pre-determined triggers from a voice of a speaker; and, in response to identifying the one or more pre-determined triggers, dynamically creating, by the at least one processor, a voice recognition template for the voice of the speaker, and using, by the at least one processor, the voice recognition template and voice isolation to focus on the voice from the speaker.
Referring now to the drawings in which like reference numbers represent corresponding parts throughout:
The descriptions of the various embodiments of the present invention have been presented for purposes of illustration, but are not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The terminology used herein was chosen to best explain the principles of the embodiments, the practical application or technical improvement over technologies found in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.
In various embodiments, “voice” may refer to speech or other audible sounds received from a human, an animal (e.g., a dog, a bird, a dolphin, etc.), a computer, etc.). In certain embodiments, a speaker is a human who can make audible sound (either by the human's own voice or by mechanical or computer means (e.g., if the user is unable to use a voice to speak). In certain embodiments, a speaker may be any animal or any computing system that can make an audible sound. Then, the one or more triggers 120 may be trigger keywords (e.g., “Hello”) or other pre-defined, audible sounds (e.g., a bark of a particular dog owned by the listener). The voice focus system 110 listens for one or more triggers 120 that indicate that a listener (e.g., a person holding the smartphone or the wearer of a hearing aid) is being addressed by a speaker, then the voice focus system 110 isolates the voice of the speaker and cancels out background noise. The background noise may be from other speakers or may be other types of noise (e.g., ambient noise, music, construction noise, etc.). By isolating the voice of the speaker and cancelling out background noise, the voice focus system “focusses” on the speaker.
The voice recognition may be described as identifying the speaker by, for example, characteristics of their voices (voice biometrics) and identifying what words the speaker is saying. The voice biometrics may be part of the voice recognition template. Then, the voice focus system 110 determines whether the words are triggers.
In block 202, in response to the one or more trigger words being identified, the voice focus system 110 dynamically creates a voice recognition template for the voice of the speaker or updates the voice recognition template for the speaker, if one exists. In certain embodiments, the listener is provided with the option of whether to store a created voice recognition template, A voice recognition template may be described as a data set containing parameters for speaker recognition and settings for earpiece configuration. The parameters may include unique voice biometrics related to the speaker's voice.
In block 204, the voice focus system 110 uses the voice recognition template and voice isolation to cancel background noise and focus on the voice from the speaker. In certain embodiments, focusing on the voice includes isolating, from the background noise, words or other audible sounds from the speaker.
Thus, the voice focus system 110 uses a two part approach to focus on a voice of a particular speaker when there are multiple speakers or noise (e.g., music) in addition to the voice of the particular speaker. First, the voice focus system 110 uses voice recognition to listen for a predetermined trigger directed to a listener (e.g., “Excuse me John” or “Hey John”). Second, a voice is identified as trying to address the listener, the voice focus system 110 then identifies that speaker's voice recognition template and uses voice isolation to “tune in” the speaker who addressed the listener.
In certain embodiments, when multiple speakers address a listener simultaneously or nearly simultaneously (e.g., within seconds of each other), the voice focus system 110 dynamically creates voice recognition templates for each of the multiple speakers. In certain embodiments, the voice focus system 110 may select one of the multiple speakers to focus on using various factors. In certain embodiments, the factors are one or more keywords, clarity of the conversation, direction of the speaker, and existing, stored speaker voice recognition templates.
It is understood in advance 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 email). 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 comprising a network of interconnected nodes.
