摘要
A method (600) includes receiving audio data (120) characterizing a hotword event detected by a first stage hotword detector (210) in audio (118) captured by a user device (102). The method also includes processing, using a second stage hotword detector (220), the audio data to determine whether a hotword is detected in a first segment (121) of the audio data. When the hotword is not detected by the second stage hotword detector, the method includes, classifying the first segment of the audio data as containing a negative hotword that caused a false detection of the hotword event in the streaming audio by the first stage hotword detector. Based on the first segment of the audio data classified as containing the negative hotword, the method includes updating the first stage hotword detector to prevent triggering the hotword event in subsequent audio data that contains the negative hotword.
