Gemini TTS API Static Noise

[leocoppens]

Hi,

I am trying to use Gemini 2.5 Pro/Flash TTS. However when I use the exact script provided in the google aistudio , the audio responds and saves, but is just static noise. The duration varies with the length of the text though.

Please help.
Thanks

Hi @leocoppens, Thanks for reaching out us!

We tried to reproduce the issue but we didn't observe any issue we were able to listen the audio without any noise using both the options you mentioned.
Thanks
