Claim 0:
1. A computer-implemented method for audio type detection, the method comprising:
receiving first audio data from a microphone array of a device, the first audio data corresponding to a first time interval and a second time interval occurring after the first time interval;
generating, using the first audio data, first data corresponding to a first sound source, wherein the first sound source is represented in a first portion of the first audio data;
generating, using the first audio data, second data corresponding to a second sound source, wherein the second sound source is represented in a second portion of the first audio data;
determining, using a wakeword detector, that a third portion of the first audio data received during the second time interval represents a wakeword;
determining a first power value corresponding to a first portion of the first data that is associated with the second time interval;
determining, based on the first portion of the first data, a first confidence value that represents a first likelihood that the first sound source corresponds to the wakeword;
determining a second power value corresponding to a first portion of the second data that is associated with the first time interval;
determining, using the second power value, that noisy conditions are present in an environment of the device;
determining, using the first power value and the first confidence value, a first value that represents a second likelihood that the first sound source corresponds to the wakeword;
determining that the first value exceeds a first threshold value;
associating the wakeword with the first sound source and generating second audio data that corresponds to a fourth portion of the first audio data in response to determining that the first value exceeds the first threshold value; and
causing language processing to be performed on the second audio data.
