Description
This PR extends the transcribe endpoints to also include word timestamps. Currently this is only implemented for the faster-whipser backend, but could also be added for other backends if supported by them. I tried to add whisper.cpp, but apparently there is some outstanding issue.
The individual words are returned twice, once as part of each segment, and once as a top level element. The top level element is to comply with the OpenAI spec, the words per segment to not lose any information which might be useful.
Additionally, the endpoint is adapted to return timestamps in seconds to comply with the OpenAI spec.
This PR fixes #9306
