Text to voice generate 13 minutes noise sound for a small text

Hi,

I have been using the gpt-4o-audio-preview and it is working fine, but sometimes for a very small text when I set the temperature to 0.1 it generates a large audio with noise sound. I tried a few times, and I paid more than $30 just for 3-4 time call. I believe there is a bug both for the cost evaluation and for generating voice.

Cheers,

I just saw that it ha sbeen previously reported:
