Abstract
Systems and methods for noise reduction using synthetic audio are disclosed. One or more playback devices include first microphone(s) (e.g., air-conduction microphone(s)) and second microphone(s) (e.g., bone-conduction microphone(s)). In operation, based on a user voice input, first and sound data streams are captured via the first and second microphone(s), respectively. The first sound data stream is evaluated to determine whether a noise threshold is exceeded. While the noise threshold is not exceeded, a synthetic sound data model is trained based on the first and second sound data streams. An audio output stream based on the first sound data stream is communicated to at least one second playback device. When noise is detected in the first sound data stream, a synthetic audio stream is mixed into the output audio stream. The synthetic audio stream can be produced based on the synthetic sound data model.
