To ensure users are properly notified when a TTS service encounters an error (such as quota exhaustion, API issues, or connection failures), TTS workers running in separate processes must propagate errors back to the main process (core.py).
When a TTS worker (e.g. steprealtimettsworker, qwenrealtimettsworker, etc.) catches an error, it MUST NOT only log the error using logger.error(). It MUST ALSO send the error message back to the main process through its responsequeue using the explicit tuple format ("error", errormsg).
This ensures that core.py's ttsresponsehandler can intercept the error and translate it into a frontend WebSocket message (type: 'status'), triggering a user-friendly Toast notification (e.g., "💥 免费TTS限额已耗尽").
Convenzione per segnalare errori dai lavoratori TTS multielaborazione al frontend del processo principale. Utilizza questa competenza durante la modifica, l'aggiunta o il debug dei lavoratori TTS in tts_client.py per garantire che gli errori di connessione, le quote e i limiti API visualizzino correttamente le notifiche Toast all'utente anziché fallire silenziosamente.
