      Custom hotwords can significantly improve Automatic Speech Recognition (ASR) accuracy in recognizing proprietary words. When words have the same pronunciation and the same tone, hotwords with higher weights will be prioritized for recognition. Currently, only hotword configurations for Mandarin Chinese and English are supported. The hotword configuration will take effect 10 minutes after update.

      Creating a Library

      1. Log in to the CSS console, and click Feature Configuration > Live Subtitles > Custom Hotwords.
      2. Click Create library. In the pop-up window, you can fill in configuration items on the Create Hotword Lexicon page based on your actual service needs.

      Multiple hotwords are separated by commas, with a maximum of 128 hotwords.
      Words and weights are separated by a vertical bar (|), for example, Tencent Cloud|10, ASR|5, ASR|10. The weight range for hotwords is 1 to 10. The higher the weight of a hotword, the higher the probability of being recognized.
