Abstract
A system configured to perform audio type detection for sound source localization (SSL) data is provided. A device processes audio data representing sounds from multiple sound sources to determine SSL data that distinguishes between each of the sound sources. To identify an audio type associated with a sound source and/or track individual sound sources over time, the device can determine a correlation between the SSL data and an audio event. Examples of audio events include a wakeword component detecting a wakeword or an acoustic event detector detecting a particular acoustic event. The device may determine a correlation between wakeword data indicating that a wakeword is represented in the audio data and SSL data for each individual sound source. The device may then identify a sound source that is most strongly correlated to the wakeword data and associate the wakeword and a corresponding voice command with the sound source.
