edge_tts_source.py overwrote the shared SDK header:
WSS_HEADERS["User-Agent"] = DEFAULT_USER_AGENT
replacing edge-tts' browser-like UA (Mozilla/5.0 ... Edg/143.0.0.0) with
"astrbot/<version>". Microsoft's readaloud WebSocket endpoint rejects a
non-browser UA with:
403, message='Invalid response status',
url='wss://speech.platform.bing.com/consumer/speech/synthesize/readaloud/edge/v1'
so Edge TTS failed for every reply.
Reproduction (same machine, same text):
- SDK default UA -> synthesis succeeds (9.7 KB mp3)
- UA set to "astrbot/4.28.1" -> raises inside edge_tts.communicate.stream
Fix: keep the SDK default UA and drop the two imports that become unused.
Verified locally: synthesis works again and the WebUI voice-call plugin can
hear the bot's replies.

Problem
astrbot/core/provider/sources/edge_tts_source.pyoverwrote a shared SDK header:This replaces edge-tts' browser-like User-Agent
with
astrbot/<version>. Microsoft's readaloud WebSocket endpoint rejects anon-browser UA, so Edge TTS failed for every reply:
Reproduction
Same machine, same text, only the UA differs:
astrbot/4.28.1edge_tts.communicate.streamConfirmed against the live endpoint, and it matches the 403 logged by AstrBot
on every TTS attempt (voice replies, WebUI voice-call plugin, etc.).
Fix
Keep the SDK default User-Agent and drop the two imports that become unused.
A comment records why the header must not be overwritten.
Verification
silent because TTS always failed).
