摘要： Techniques are described for own-voice suppression using separate sound filters. Sound from a local area is captured using an acoustic sensor array. The captured sound includes noise from the local area and the user's voice. A first set of statistical properties associated with the noise and a second set of statistical properties associated with the user's voice are determined. A first sound filter is generated based on a target transfer function and both sets of statistical properties. A second sound filter is generated based on the target transfer function and the second set of statistical properties, but not the first set of statistical properties. The first sound filter and the second sound filter are applied to different parts of an audio signal generated based on the captured sound, thereby forming audio content in which the user's voice is suppressed for presentation of the audio content to the user.

摘要： Various embodiments set forth techniques for directional sound modification. In one aspect, a system includes a plurality of audio sensors configured to acquire sound from an environment and at least one processor coupled to the plurality of audio sensors. The at least one processor is configured to determine a direction within the environment, generate an audio signal based on sound acquired from the direction within the environment, and transmit the audio signal to at least one audio output device to generate audio output. The audio output combines with sound from the direction within the environment to produce a modified sound.
