The Speech Recognition Channel function identifies text from spoken audio in videos and organizes it into subtitles with precise timestamps.

Friendly Tip: Some channels, such as OpenAI and ByteDance Volcano Engine, require you to pre-set the API address or secret key (SK) before use. Don't worry, it's simple! Just click the "Speech Recognition Settings" menu at the top of the software and enter the relevant information.
