Methods, systems, and user devices, including computer programs encoded on a computer storage medium, are disclosed for suppressing hot word triggers when a hot word in recorded media is detected. In one aspect, a method includes receiving, at data processing hardware, audio data corresponding to playback of a media content item, the audio data including an audio watermark and an utterance of a command ahead of a hotword; determining, by the data processing hardware, that the received audio data includes a hotword; processing, by the data processing hardware, the audio data to: identify an audio watermark included in the audio data; and determining a bit stream corresponding to the audio watermark; and based on the determined corresponding bitstream of the audio watermarks, determining, by the data processing hardware, to bypass execution of the command preceded by the hot word without accessing the audio watermark database to identify a matching audio watermark. 公开了用于当检测到记录的媒体中的热词时抑制热词触发的方法、系统和用户设备，包括在计算机存储介
