- speak() hing weil pygame.time.wait() die asyncio Event-Loop blockierte. Fix: time.sleep(0.05) statt pygame.time.wait() im Playback-Loop. - asyncio.new_event_loop() statt asyncio.run() — thread-sicher, kein "event loop already running" in Worker-Threads. - _speak_lock verhindert parallele TTS-Aufrufe. - Stimme: de-DE-SeraphinaMultilingualNeural als Default (modern, weiblich, multilingual neural). Dropdown in Settings mit allen DE/EN Optionen. - speak()-Signatur: voice + rate als Parameter (statt config-Import). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
