Hi ZHOU JICHAO,
Greetings & Welcome to Microsoft Q&A forum! Thanks for posting your query!

If the confidence score is always 0, it could be due to a few reasons. One possibility is that the audio quality is poor, which can affect the accuracy of the speech recognition. Another possibility is that the language model being used is not appropriate for the audio being processed.
Ensure that the audio being processed is of good quality. This can be achieved by using a high-quality microphone and recording in a quiet environment.

If the default language model is not providing accurate results, you can create a custom language model that is tailored to your specific use case. This can be done using the Custom Speech Service.

I hope this information helps. If you have any further queries, please let us know. Thank you!
