We have a problem that many of our voice files cannot get recognized when we used SpeechRecognition. They mostly fail with InitialSilenceTimeout reason.
When we listen the voices, they don't sound any silence in the beginning and also there are couple other voice files get recognized correctly. So we don't think it is code issue but we cannot figure out why it fails for some voices. There is Conversation_Initial_Silence_Timeout property and we set it to some seconds, but that doesnt help.
Also if I test exact same voice files in SpeechStudio with same Resourcegroup, they pass the test and recognized.
Does anyone had any similar issue? would there be any property that we missed to configure in the code?
