Voice systems build · Private practice tool
Fast voice assistance with explicit controls and fail-closed boundaries.
Niyam Voice Bridge combines bounded microphone capture, Deepgram transcription, local deterministic answer matching, optional grounded drafting, and deliberate Windows audio playback.

- Practice audio/transcripts kept in memory
- Verification
- 5/5 bounded synthetic room-audio cycles
01 / Design
Nothing should speak or send data by accident.
Capture, transcription, AI drafting, voice generation, and playback are separate explicit actions. Audio and transcripts are not written to repository/runtime logs, and optional remote drafting receives selected verified facts rather than arbitrary files.
02 / Engineering
Keep a fast local path even when remote AI is slow.
- Push-to-talk physical-microphone capture with bounded duration.
- Deepgram transcription and deterministic local answer ranking.
- Optional grounded Codex drafting that fails closed on timeout.
- Explicit Windows audio routing and dual-output playback work.
- Metadata-only logging that excludes prompts, answers, transcripts, and secrets.
03 / Evidence boundary
A successful synthetic test is not a product claim.
A five-question synthetic room-audio test completed 5/5 cycles, but the repository explicitly does not claim proven performance for real interviews, arbitrary accents/noise, commercial use, or a passed realtime Codex latency gate.
