# Voice Customer Coach A greenfield Next.js app for practicing Mom Test-style customer interviews with realtime Gemini voice personas, a silent visual coach, and an exportable post-session debrief. ## What is built - Apple-inspired setup flow where a website URL alone is enough; optional text, images, pitch deck PDFs, and audio memos enrich the context. - Context synthesis route using Gemini 3.5 Flash, with Managed Agent notes attempted for URL/image context and graceful local fallback when no API key is present. - Curated customer personas plus a Custom persona text box, all with voice names for `gemini-3.1-flash-live-preview` and grounded by `content/customer-speech.md` so they sound like real humans instead of assistants. - Ephemeral Live API token route that keeps `GEMINI_API_KEY` server-side. - Browser Live session hook with AudioWorklet PCM capture, typed text input, PCM playback, input/output transcription accumulation, silence nudges, and teardown. - Synced text transcript for both spoken and typed founder turns plus customer voice output transcription. - Live customer persona attempts Google Search grounding for public facts, competitors, pricing, docs, reviews, and websites mentioned during roleplay. - Parallel Mom Test coach evaluators on `gemini-3.5-flash` with explicit thinking levels and deterministic fallback heuristics. - Session report generation, markdown copy, and `.md` download. ## Models | Layer | Model | | --- | --- | | Voice persona | `gemini-3.1-f
