transcription gets stuck repeating the same words #616
Description
Sometimes, the generated transcription gets stuck repeating the same words, and there is a warning :
Compression ratio threshold is not met with temperature 0.0
The problem is that the default value for temperature is 0 in speaches. The problem can be solved if we pass a higher temperature but it will apply to all the transcript.
The default behavior in faster-whisper is that if temperature is not specified, it is considered 0 and only when compression ratio threshold or log probability threshold are not met for a certain segment then it will try with temperature 0.2 and so on from the list [0, 0.2, 0.4, 0.6, 0.8, 1.0] for that segment.
See fix in #615 (original fix in #553) : Change the default value for temperature to the same default list used in faster-whisper to let it handle retries for segments where compression ratio threshold or log probability threshold criterias are not met.
