The portal-assistant voice-assistant stacks (portal-tts, portal-stt,
portal-assistant) were applied to the live cluster from feature branches but
never landed on master — the GitOps source of truth. This lands all three and,
in portal-tts, fixes Bulgarian speech.
Bulgarian was unintelligible: the local Piper voice (bg_BG-dimitar-medium via
espeak-ng) mangles Bulgarian consonants — a synth->Whisper round-trip turned
"Добър ден" into "Обърден", and a user heard pure gibberish. English was fine.
portal-tts now runs openai-edge-tts (Microsoft edge-tts neural voices) for BOTH
languages instead of Piper — ADR-0003 always named edge-tts as the online
Bulgarian-quality fallback. Validated before landing: edge bg round-trips
through Whisper verbatim ("Добър ден! Как сте днес? ..."). The gateway maps
detected language bg/en to the edge voice names via new TTS_VOICE_BG /
TTS_VOICE_EN env (bg-BG-KalinaNeural / en-US-AvaNeural). No GPU, no NFS model
store, no secrets — edge fetches voices from Microsoft per request (egress
verified). The assistant already needs the internet for the Claude brain, so an
online TTS adds no new failure mode.
The brain stays Sonnet with no extended thinking (already the default — a live
turn answers directly in ~3.4s), per the latency-over-smartness ask.
