The section this PR adds claimed speech.voice was the forwarded voice key. It is not: the openai-speech transport builds {model, input, response_format, voice?} and sets voice only when the CALL passed voice_id, tts.localVoice is the local Kokoro backend key, and speech.voice is the TUI speak-aloud voice whose enum is Kokoro-only. A restarted session proved it the honest way - the tts device arrived at 7772 with no voice key and got "unknown voice None; available voices: narrator1, narrator2, narrator3" - so the fresh-process success earlier that day was the run that was told to pass voice_id, not evidence of a setting.
The law now reads: voice comes from voice_id alone, so a voice-less call is the harness default shape (the endpoint grew DEFAULT_VOICE in its own PR to answer it), and speech.voice must stay a Kokoro name - a pack name there breaks the vocalizer and does nothing for synthesis. config.yml reverted to am_fenrir on the operator box, and the worklog entry that recorded narrator1 as wiring carries the correction.
