How can I extend STT listening time?

How can you extend STT listening time?

Hello, I
use the tts and stt from the ha cloud. As an integration I use StreamAssist so that I can get the data and from this I have built a conversation mode that automatically reactivates the MIC at the end of the TTS if you want. But after the WakeWord is recognized, the stt listening is deactivated after less than a second, so the voice recognition is switched off. I would like to extend the timeout when it is quiet. How can I adjust the STT time?
Thanks
