Abstract: Methods, systems, and devices for signal processing are described. Generally, as provided for by the described techniques, a wearable device to receive an input audio signal from one or more outer microphones, an input audio signal from one or more inner microphones, and a bone conduction signal from a bone conduction sensor based on the input audio signals. The wearable device may filter the bone conduction signal based on a set of frequencies of the input audio signals, such as a low frequency portion of the input audio signals. For example, the wearable device may apply a filter to the bone conduction signal that accounts for an error in the input audio signals. The wearable device may add a gain to the filtered bone conduction signal and may equalize the filtered bone conduction signal based on the gain. The wearable device may output an audio signal to a speaker.

Abstract: A device includes a memory configured to store category labels associated with categories of a natural language processing library. A processor is configured to analyze input audio data to generate a text string and to perform natural language processing on at least the text string to generate an output text string including an action associated with a first device, a speaker, a location, or a combination thereof. The processor is configured to compare the input audio data to audio data of the categories to determine whether the input audio data matches any of the categories and, in response to determining that the input audio data does not match any of the categories: create a new category label, associate the new category label with at least a portion of the output text string, update the categories with the new category label, and generate a notification indicating the new category label.

Abstract: An electronic device includes a classifier circuit, a ranking circuit, and a data generator circuit. The classifier circuit is configured to determine, based on first data indicating samples of sounds detected at a plurality of geographic locations, a plurality of acoustic event classifications associated with the plurality of geographic locations. The ranking circuit is configured to determine a plurality of index scores associated with the plurality of geographic locations by ranking each of the plurality of geographic locations based on the plurality of acoustic event classifications. The data generator circuit is configured to generate, based on the plurality of index scores, second data indicating a geographic map corresponding to the plurality of geographic locations. The second data further indicates the plurality of index scores and a prompt to enable a search for a particular type of acoustic event.

Abstract: A method of processing audio may include receiving, by a computing device, a plurality of real-time audio signals outputted by a plurality of microphones communicatively coupled to the computing device. The computing device may output to a display a graphical user interface (GUI) that presents audio information associated with the received audio signals. The one or more received audio signals may be processed based on a user input associated with the audio information presented via the GUI to generate one or more processed audio signals. The one or more processed audio signals may be output to, for example, one or more output devices such as speakers, headsets, and the like.

Abstract: Disclosed is an application interface that takes into account the user's gaze direction relative to who is speaking in an interactive multi-participant environment where audio-based contextual information and/or visual-based semantic information is being presented. Among these various implementations, two different types of microphone array devices (MADs) may be used. The first type of MAD is a steerable microphone array (a.k.a. a steerable array) which is worn by a user in a known orientation with regard to the user's eyes, and wherein multiple users may each wear a steerable array. The second type of MAD is a fixed-location microphone array (a.k.a. a fixed array) which is placed in the same acoustic space as the users (one or more of which are using steerable arrays).

Abstract: A system includes a memory configured to store data associated with a service that is available. The system also includes a microphone associated with an acoustic space and configured to receive an audio input produced by a person. The system further includes a sensor located within the acoustic space and configured to detect vibrations produced by the person. The system includes a processor coupled to the memory, to the microphone, and to the sensor. The processor is configured to conditionally authorize execution of the service requested by the person, the service conditionally authorized based on the audio input and the vibrations.
