Microsoft patents audio effect that turns group speech into background chatter

1. A computer-implemented method for simulated choral audio chatter in communication systems, the method comprising: receiving audio data from each of a plurality of users participating in a first group of a plurality of groups for an event using a communication system; receiving audio data from each of a plurality of users participating in a second group of the plurality of groups for the event, wherein each of the plurality of users participating in the first group are different from each of the plurality of users participating in the second group; generating first simulated choral audio chatter based on speech of the audio data received from each of the plurality of users in the first group, wherein the generated first simulated choral audio chatter removes recognizable speech of the audio data and is audible; concurrently to generating the first simulated choral audio chatter, generating second simulated choral audio chatter based on speech of the audio data received from each of the plurality of users in the second group, wherein the generated second simulated choral audio chatter removes recognizable speech of the audio data, is audible, and is different from the generated first simulated choral audio chatter; providing the generated first simulated choral audio data to the plurality of users in the second group; and concurrently to providing the generated first simulated choral audio data to the plurality of users in the second group, providing the generated second simulated choral audio data to the plurality of users in the first group.
