TLDR:Words like 'amazing' and 'wow' speed up delivery by 4%. Words like 'however' and 'therefore' slow it by 4%. Use this to add natural rhythm.

Frequently Asked Questions

Can I disable automatic speed variation?

Speed variation is built into the engine and works automatically—there's no toggle to flip. If you want flat, consistent pacing, keep your script neutral by avoiding strong emotion words.

Does this work in all languages?

Currently, emotion keyword detection works for English content. Other languages use the base prosody rules without keyword-based adjustments.
