Add Audio APIs

[teerapap]

This pull request is to add Audio APIs.
https://platform.openai.com/docs/api-reference/audio/create

It supports two new APIs.

• Create Transcription API
• Create Translation API

This should fix #272 as well.

If this PR has any problems, please let me know.

Thanks

Hello,

Oh ! I didn't see your Pull Request, I just finished adding the audio API. What a shame. It looks like we coded pretty much the same thing, the only difference being in the TranscriptionSegment. What source did you use to get this information? Because when I tested from Postman, I only got a return containing "text", nothing more.

That being said, I thank you for your modifications :-).

I'm not going to add another PR, but I'm still leaving my modifications here, just in case : https://github.com/jpagny/openai-java/tree/feature/add_audio_api

Have a nice day.

Hi @jpagny

I just did this PR two days ago. I guess it was bad timing. 😅

The response contains segments property and other properties when the request has response_format=verbose_json.

You can try it.
