Abstract: A communication system provides audio content to one or more client devices capable of playing spatialized audio content. For example, the communication system receives audio content from a client device and transmits the audio content to other client devices to be played for users. The communication system dynamically modifies audio content transmitted to different client devices based on a payload including audio parameters (e.g., local area acoustic properties, an audiogram for a user, a head related transfer function for a user, etc.) received from a client device.

Abstract: 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.
