Zusammenfassung:Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for hotword trigger suppression are disclosed. In one aspect, a computer-implemented method causes data processing hardware to perform operations comprising: receiving audio data corresponding to playback of an item of media content, the audio data captured by a microphone of a computing device; detecting an utterance of a predefined hotword in the audio data; in response to detecting the utterance of the predefined hotword: initiating performance of speech recognition on speech following the utterance of the predefined hotword in the audio data; activating a light on the computing device to flash while the speech recognition is performed on the speech; extracting an audio signature from the audio data; and determining that the audio signature extracted from the audio data corresponds to a known recording that contains or is associated with the predefined hotword; and in response to determining that the audio signature extracted from the audio data corresponds to the known recording: ceasing the performance of speech recognition on the speech following the utterance of the predefined hotword in the audio data; and deactivating the light on the computing device.
