Environment Details

Hi guys,

I was experiencing so many problems with voice instability, one words expressions going crazy etc. in my case, I realized that the problem was not related to short expressions, but rather... any sentence ending with an exclamation mark, i.e. "!".

So instead of attributing custom speed to short sentences, I simply replace dynamically all "!" by a normal "." in the text fed to the TTS, and it got rid of all voice instability in my case. The voice is very enjoyable, and a bit calmer now! Just wanted to share with you.

If any update is brought to this model, it should be with expressive sentences, that's where the bug is I think.

Steps to Reproduce

replace dynamically all "!" by a normal "."

✔️ Expected Behavior

no voice instability

❌ Actual Behavior
