Speech generation produces noise

[MarwenSami]

Bug Report

Overview

Using Speech API the output AudioClip doesn't seem to play correctly on unity.
When we play the final audio clip it's just noise playing.
When we play the partial audio clip it sounds crunched (the parts that are generated are overlapping).

I'm using v8.4.4

To Reproduce

Steps to reproduce the behavior:

        var api = new OpenAIClient(apiKey);
        var request = new SpeechRequest("Hello there! I'm sorry, I couldn't find anything. What would you like to do?");
        
        var fullClip = await api.AudioEndpoint.GetSpeechAsync(request, clip =>
        {
            audioSource.PlayOneShot(clip.AudioClip);
 
        });
        
/* OR when I play the final clip it's just noise 
       
        audioSource.PlayOneShot(fullClip.AudioClip); */

Please update to the latest version 8.6.5

My bad, actually my project was already working with v8.6.5 when I encountered the issue.

I'll take a look and see if maybe I missed something in the last update.

@MarwenSami change the SpeechResponseFormat to PCM as a workaround

@MarwenSami I was able to find the source of the problem, and will be fixed in 8.6.6
