# Praxis — v0.1 Foundation
|
|
|
|
Voice-first AI apprenticeship platform. v0.1 is a **tech-validation harness** (per G-008) for the minimal viable voice loop: a single learner speaks to an AI tutor playing a Customer Service role-play scenario, hears a <600ms-latency response, receives an end-of-session coaching debrief, and has the session logged to SQLite.
|
|
|
|
## Status
|
|
|
|
Phase 1 (minimal viable voice loop) — code-complete, pending live API keys for runtime verification.
|
|
|
|
## Stack
|
|
|
|
- **Orchestration:** Pipecat (D-017) with Silero VAD + interruptibility
|
|
- **ASR:** Deepgram Nova-3 streaming (D-013)
|
|
- **LLM:** Ollama Cloud direct API (D-020) — `gemma4:cloud` (role-play) + `deepseek-v4-flash:cloud` no-think (debrief)
|
|
- **TTS:** Cartesia Sonic (primary, D-014) / Piper (self-hosted, R4 mitigation) — behind an interface
|
|
- **Client:** React + Vite + WebRTC (Pipecat client SDK, D-015)
|
|
- **State:** SQLite `praxis.db` (D-007, single hardcoded learner, no auth)
|
|
|
|
## Layout
|
|
|
|
```
|
|
server/ Pipecat pipeline, services (TTS/LLM/Guardrail interfaces), scenario runtime, adapters
|
|
client/ React + Vite + WebRTC learner surface
|
|
scenarios/ YAML scenario definitions (D-018)
|
|
db/ SQLite schema, migrations, async store
|
|
scripts/ Latency probes (R1-R4), e2e smoke
|
|
tests/ Unit + e2e
|
|
docs/ Latency report, debrief templates
|
|
```

|
|
## Quickstart
|
|
|
|
1. Copy `.env.example` → `.env`, fill in `DEEPGRAM_API_KEY`, `CARTESIA_API_KEY`, `OLLAMA_API_KEY`.
|
|
2. Install server deps: `pip install -e ".[dev]"`
|
|
3. Install client deps: `cd client && npm install`
|
|
4. Run probes: `python scripts/probe_deepgram.py` (etc.)
|
|
5. Run server: `python -m server`
|
|
6. Run client: `cd client && npm run dev`
|
