Abstract: A watch for detecting a voice command which includes a touchscreen, a microphone, a speaker, a memory, and a processor that is wirelessly connected to an earphone that includes an earphone microphone where at least one of the microphones are used to determine voice command.

Abstract: A method of generating a suppression signal using an adaptive filter, using an ear canal microphone signal from an earphone and an audio content signal and combining the suppression signal with others signals to generate a mixed signal that is sent to a speaker.

Abstract: The disclosure describes an earphone that include a biometric sensor, where the biometric sensor can detect levels of gas concentration. Where the gas levels are reported to a user if exceeding a threshold value and where the earphone includes a microphone, speaker, memory and a processor.

Abstract: A method and device for automatically increasing the spectral bandwidth of an audio signal including generating a “mapping” (or “prediction”) matrix based on the analysis of a reference wideband signal and a reference narrowband signal, the mapping matrix being a transformation matrix to predict high frequency energy from a low frequency energy envelope, generating an energy envelope analysis of an input narrowband audio signal, generating a resynthesized noise signal by processing a random noise signal with the mapping matrix and the envelope analysis, high-pass filtering the resynthesized noise signal, and summing the high-pass filtered resynthesized noise signal with the input narrowband audio signal. Other embodiments are disclosed.

Abstract: A personal audio assistant that includes a speaker, microphone, memory, and a logic circuit that receives a request from a user for audio content, where the logic circuit retrieves a listening history envelope of the user, then retrieves a set of personalized playlist content from a remote server using the listening history envelop as a filter and sends a list of the set of personalized playlist content to the user.

Abstract: A wearable accessory for delivery of personalized audio service includes a first microphone for capturing sound, a first speaker for playing media, a logic circuit for creating a personalized Head Related Transfer Function (HRTF) to enhance listening experience of the media, a communication module for accessing the Internet and to provide access to the media in response to capturing the sound, and a memory storage unit for storing information related to the captured sound. Other embodiments are disclosed.
