fix: transcribe verbosity

[nick-konovalchuk]

I've hidden "Detected langauge: " massage behind verbose flag.
Also fixed the flag usage with tqdm

[jongwook]

I actually intended the two to be displayed even when --verbose is False, thinking it'd help the user notice any language detection errors and show the progress/ETA without flooding the console.

[nick-konovalchuk]

@jongwook well, ETA is disabled when verbose=True, which is misleading as it seem to me. Also, the language tag is returned as a part of the result. Do you really need to print it if you return it?

[jongwook]

The language tag is returned in the result, but for those calling whisper in the command line (as it seems to be a popular use case) the detail is lost.

Regarding ETA: that's true; it's not the most intuitively named options but I thought both formats have merits (like below) and thought it'd be nice to have these verbose/concise output options, but probably better not mix up those two.

We can maybe make it an integer level for verbosity if a totally silent output is desired by many ..

@jongwook
How about str verbosity like "full", "minimal" and "silent"? I might add it real quick

• full being equivalent to verbosity=True
• minimal being equivalent to verbosity=False
• silent being equivalent to verbosity=False from current PR

[jongwook]

I'd like to avoid magic string if possible. It's a bit unorthodox but I'm inclined to making it an Optional[bool] and use None/False/True so verbose=None (i.e. silent) is the default in transcribe() but from the command line it selects either True or False.

I can make these edits on this PR if you'd like/don't mind.

[nick-konovalchuk]

Don't bother yourself, I have nothing to do at the moment

[jongwook]

Could you make this verbose is not False? Thank you.

[nick-konovalchuk]

Done
