Is there a way to maintain consistency in Gemini speech generation?
I’ve been testing speech-to-text with Gemini 2.5 Pro Preview TTS for a couple of weeks, and even though I always use the same voice (“zephyr”) and the same prompt (“Read aloud in a warm and friendly tone”), almost every audio generation sounds different. Sometimes it’s consistent, but that’s not usually the case.

Hi @Fabi_Rodrigues
When you say the output sounds different, could you describe the variations you’re hearing? For example, is it a change in pitch, cadence, emotion, or something else entirely?
And also, are you trying to do this in AI Studio or using API?
