Systems and processes for analyzing audio input for efficient speech and music recognition are provided. In one example process, an audio input can be received. A determination can be made as to whether the audio input includes music. In addition, a determination can be made as to whether the audio input includes speech. In response to determining that the audio input includes music, an acoustic fingerprint representing a portion of the audio input that includes music is generated. In response to determining that the audio input includes speech rather than music, an end-point of a speech utterance of the audio input is identified.
