Custom hotwords can significantly improve Automatic Speech Recognition (ASR) accuracy in recognizing particular words. If different words have the same pronunciation, the hotword with the highest weight will be used. Currently, hotwords are only supported for Mandarin Chinese and English. Hotwords take effect 10 minutes after successful configuration.
