I have a call back connected to the wordboundary event and it was working okay until a few days ago. Now the event always returns 0 for audio offset and duration but the audio itself is fine.
I'm using azure-cognitiveservices-speech 1.36.0. Problem also occurs with 1.33.0It was working (on v. 1.33.0) a week or so ago and seems to have stopped. Any ideas what could be causing it?

2024-04-09T06:27:55.3633333+00:00 Update. I upgraded to 1.37.0 and noticed that the audio_offset seems to update but only at the end of a sentence. Its as if audio_offset accumulates the duration and audio_offset is set within the streaming response when a full stop is encountered. This screen capture shows the wordboundary event details within a chunk of text sent for speech synthesis. This behaviour is observed in each chunk of text with the audio offset being reset to zero at the start of each chunk.

Are you still facing this issue? May I know the SDK language you are working on?
