This is a known Edge-TTS 403 error caused by changes Microsoft made to the free Edge-TTS API validation logic after 2026-10-10. Your log shows WSServerHandshakeError: 403 from speech.platform.bing.com, which confirms this.

Actions you can take now:

  1. Use a different TTS channel – Switch to another available voice provider (e.g., gTTS, Qwen-TTS, or any other configured TTS service) until the fix is released.
  2. Try a VPN with a different region – In some countries/continents, the Edge-TTS service still works. Experiment with switching your VPN node to a different country or continent.
  3. Wait for v4.16 – The next version is expected to fix this issue. Until then, the above workarounds are your best options.

Additional note: If you have a proxy configured, you can also try creating an empty file named edgetts-noproxy.txt in the software root directory to force Edge-TTS to bypass the proxy, but the primary cause here is the service-side change.
