Abstract
Systems and methods are disclosed for providing voice and noise activity detection with audio automixers that can reject errant non-voice or non-human noises while maximizing signal-to-noise ratio and minimizing audio latency.
Claims21
A method, comprising:
- determining whether non-speech audio is present in an audio signal of a channel initially gated on by a mixer, wherein the mixer generates a mixed audio signal based on at least the audio signal of the channel initially gated on;
- and
- when the non-speech audio is determined to be present in the audio signal of the channel initially gated on, overriding the mixer by gating off the channel initially gated on to cause the mixer to generate the mixed audio signal without the audio signal of the channel initially gated on.
A system, comprising:
- an activity detector configured to determine whether non-speech audio is present in an audio signal of a channel initially gated on by a mixer, wherein the mixer is configured to generate a mixed audio signal based on at least the audio signal of the channel initially gated on;
- and
- a channel gating module in communication with the activity detector, the channel gating module configured to when the non-speech audio is determined by the activity detector to be present in the audio signal of the channel initially gated on, override the mixer to cause the mixer to:
- gate off the channel initially gated on;
- and
- generate the mixed audio signal without the audio signal of the channel initially gated on.
