The error is caused by using the Qwen-TTS local channel to generate voice for a language (Polish) that is not currently supported by the model.

Solution:

Change the TTS channel: Do not use the local "Qwen-TTS" channel for Polish. Switch to a TTS channel that supports Polish, such as:
- Edge-TTS (Free, online, supports Polish)
- OpenAI TTS (Paid API, supports Polish)
- Azure TTS (Paid API, supports Polish)
- F5-TTS (Local, supports multi-language cloning, but you must ensure the reference audio is in a supported language and the target language is set correctly in its API).
If you must use Qwen-TTS: The current local Qwen-TTS model only supports the languages listed in the error message: ['auto', 'chinese', 'english', 'french', 'german', 'italian', 'japanese', 'korean', 'portuguese', 'russian', 'spanish']. You cannot use it for Polish.

Steps to change the TTS channel in pyVideoTrans:

In the main interface, go to the "Dubbing Channel" section.
Select a different channel from the dropdown list (e.g., "Edge-TTS").
Configure the selected channel if necessary (Edge-TTS requires no configuration).
Re-run the dubbing task.

Please refer to the relevant documentation:
