A method for a wireless personal communication using a hearing system with a hearing device comprises: monitoring and analyzing the user's acoustic environment by the hearing device to recognize one or more speaking persons based on content-independent speaker voiceprints saved in the hearing system; and presenting a user interface to the user for notifying the user about a recognized speaking person and for establishing, joining or leaving a wireless personal communication connection between the hearing device and one or more communication devices used by the one or more recognized speaking persons.

A vehicle computing system may implement techniques to emit warning sounds from a vehicle to notify other entities in an environment with the vehicle of the vehicle operation. A vehicle computing system may be configured to emit warning sounds based on a speed associated with the vehicle. The vehicle computing system may determine a planned vehicle trajectory and that a speed corresponding to the planned vehicle trajectory is associated with the warning sound emission. The vehicle computing system may determine a time that the vehicle will be at the speed and may emit the warning sound substantially at the time. In some examples, the vehicle computing system may emit a different sound prior to the time and may transition to the warning sound associated with the speed at the time. By warning other entities of the vehicle operation, the warning sound emission system may improve the safety of vehicle operation.

An earpiece in embodiments of the present invention may have one or more of the following features: (a) an earpiece housing, (b) at least one speaker, (c) a plurality of sensors disposed within the earpiece housing, and (d) a processor disposed within the earpiece housing and operatively connected to the plurality of sensors and the at least one speaker, wherein the processor is configured to use an artificial intelligence framework to evaluate sensor input from the plurality of sensors to provide advice to the user.

A hearing system includes a hearing aid (10) and personal communication device (20) connected via a short range data communication link. The hearing aid has a signal processor (13) processing an audio signal according to audio processing parameters, a sub-system applying respective sets of processing parameters for at least two modes, a classifier component (51) statistically analyzing the environment by comparing specific characteristics of an electrical input signal to one or more thresholds. A program selector component (16) selects automatically an appropriate mode for the signal processing sub-system according to the classifier output. The personal communication device offers the user an interface for controlling and interacting with the program selector component of the hearing aid, and for generating and transmitting a notification to the hearing aid. Upon reception of the notification, the processor adjusts at least one of the one or more thresholds used by the classifier component.

A vehicle selects various sound sources and outputs driving sound based on information received from the navigation system. A database stores sound sources classified as first and second emotions. A controller outputs a landmark name based on a route guidance text and outputs a ratio of the first and second emotions corresponding to the landmark name. The controller selects a first sound source from the sound sources classified as the first emotion based on the first emotion ratio, selects a second sound source from the sound sources classified as the second emotion based on the second emotion ratio and determines first and second playback periods based on the ratios of the first and second emotions. The controller outputs a first sound generated based on the first sound source during the first playback period and a second sound generated based on the second sound source during the second playback period.

A head-mounted situational awareness system and method of operation provides a head gear with a retinal display, and multiple sensory-related electrical components. A microphone array and a motion sensor are integrated into head gear. The microphone array detects incoming audio signals to generate an audio signal. The motion sensor detects position and orientation of head gear relative to audio source to generate a position signal. A processor utilizes speech-to-text software to translate the sound to text for display on retinal display. The processor utilizes a position algorithm and triangulation functions to generate a position graphic of audio source. Noise cancelling software reduces background noise to sound. A remote subsystem, or command center, communicates audio signal and position signal with the head gear to receive an audio picture of the area, and also to generate actionable information that displays in real time on the retinal display of head gear.

The present disclosure relates to binaural hearing aid systems and methods of enhancing speech of one or more desired speakers in a listening room using indoor positioning sensors and systems.

Method and devices for processing audio signals based on sound profiles are provided. A sound profile can include data related to haptic movement of the audio data which is specific to a left ear or a right ear, demographic information, ethnicity information, age information, location information, social media information, intensity score of the audio data, previous usage information, or device information. A sound profile can be customized for individual user to include the inaudible frequency range at high frequency end and low frequency end. Audio data within the inaudible frequency range can be compensated by haptic movement corresponding to the inaudible frequency range. A sound profile can further include an audio frequency range and its lowest audible volume for a user. A sound profile can be provided to a user without any action from the user's part.

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for fast role switching between master and slave roles among wireless nodes. In one aspect, wireless nodes, such as wireless earbuds, coupled to a wireless source, may dynamically and intelligently swap master and slave roles to optimize battery life in the wireless nodes.

Various implementations disclosed herein include devices, systems, and methods that that modify audio of played back AV content based on context in accordance with some implementations. In some implementations audio-visual content of a physical environment is obtained, and the audio-visual content includes visual content and audio content that includes a plurality of audio portions corresponding to the visual content. In some implementations, a context for presenting the audio-visual content is determined, and a temporal relationship between one or more audio portions of the plurality of audio portions and the visual content is determined based on the context. Then, synthesized audio-visual content is presented based on the temporal relationship.
