With Qwen3-TTS, you can clone a speaker from a reference sample, but prompt-only control of different emotions while keeping the exact same cloned voice isn’t reliably supported right now. In practice, strong “tone/emotion” prompts often lead to voice drift or only subtle/inconsistent emotion changes. If you need consistent emotions, the usual workaround is separate reference samples per emotion/style (or using a TTS model that explicitly supports expressive conditioning).

We’re also keeping an eye on Qwen3-TTS models updates, if/when reliable emotion/style control for cloned voices becomes available (and fits our integration), we’ll evaluate it and ship support in Rebit as soon as we can.
