I had previously opened a ticket regarding this. That was marked closed but the issue still persists.
Here is the comparison of the behaviour of the previous and the new version

Context
We are building a voice AI assistant for German healthcare centers, and we need to give a long message before we proceed to the AI assisted workflow.

Previous
In the previous behave the AWS transcribe was throwing errors. Post a message reached 15 seconds of length and the flow stop responding.

Curent
However, in the newer implementations, the transcribe is not throwing any errors and the system simply hangs so our issue to say long consent messages during the start of the call still persists.
