Retrieving who was speaking at each moment?

Hello, when I call the Get Call Transcript API, response includes only call_id, no lines information.

This is understandable as we speak Japanese, which might not be supported by Diaplad's AI transcription.

Still we can try transcribing by ourselves, using audio data provided by Dialpad.

The problem is that, it is difficult to guess from raw audio data who (agent or customer) was speaking at each moment.

The question is, can we somehow get that bit of information from API? We don't need actual transcription, only who was speaking.

Thanks!
