dsh-voice brings voice superpowers to the DeepSeek Harness Web UI. Whether you need hands-free real-time streaming dictation segmented on natural breath pauses or crisp voice notes with keyboard/mouse Push-to-Talk gestures, dsh-voice ensures your audio is never lost thanks to automatic multi-provider fallback chains.

• 🎙️ Streaming Dictation with VAD: Speech is automatically sliced at natural pauses (vadSilenceMs, default 700ms) and typed into the composer in real time.
• 🌊 Voice Notes with Cancel Window: Record your thought and have it automatically dispatched to the agent after a safety countdown (autoSendMs, default 4000ms).
• 🎮 Tactile Push-to-Talk:
  • Mouse: Hold the wave button — releasing sends the message; dragging pointer away discards.
  • Keyboard: Hold Ctrl (or custom hotkey) for hands-free speaking; press Esc to cancel.
• ⚡ Zero-Latency In-Browser Captions (browser): Chrome Web Speech API recognition runs 100% locally with live floating captions as you speak.
• 🛡️ Ironclad Multi-Provider Fallbacks: If your primary cloud provider runs out of credits or hits a 429 rate limit, requests seamlessly fail over down the chain.
• 🧠 Context Glossary Injection: Automatically extracts code variables and identifiers from your composer draft to steer STT model accuracy on technical jargon.
• 🎵 Embedded Audio Player: Preview, scrubber, and playback of your recorded voice message directly in chat and the composer dock.
• 🔇 Hardware Noise Suppression Toggle: Configurable in settings to toggle browser-level noise suppression, echo cancellation, and auto gain control.
• 📊 Provider Latency & Health Dashboard: Live visual telemetry of provider latency (ms), success rates, and errors directly within the settings UI.
• 🔒 Zero API Key Leakage: Keys are resolved on the host via ctx.credentials (credentialRef) and never transmitted to browser clients.
• 🖥️ Offline Local Whisper Server: Automatically boots and manages whisper.cpp (whisper-server) with on-the-fly ffmpeg transcode.
• ⚡ SenseVoice-ONNX / Sherpa-ONNX (0.8.11): Ultra-fast (~50–100ms) non-autoregressive local STT engine with automatic emotion/event tag stripping. Supports both Sherpa-ONNX HTTP and OpenAI-compatible endpoints.
• 🌐 Realtime Audio Streaming (0.8.11): Low-latency WebSocket bridge (/dsh-voice/realtime) for OpenAI Realtime API or local Sherpa-ONNX streaming. API keys stay securely on the host.
• 🌊 Liquid Wave & Dynamic Orb Visualizer (0.8.12): Smooth animated audio visualization in the recording pill with real-time mic volume reactivity. Switch between organic multi-layer liquid waves, pulsating radiant orb, classic bars, or off.

Just specify the name in your fallback chain and add the corresponding API key:

• openai (whisper-1) → OPENAI_API_KEY
• siliconflow (SenseVoiceSmall) → SILICONFLOW_API_KEY
• mistral (voxtral-mini-latest) → MISTRAL_API_KEY
• openrouter (google/gemini-2.5-flash) → OPENROUTER_API_KEY
• deepinfra (whisper-large-v3-turbo) → DEEPINFRA_API_KEY
• fireworks (whisper-v3-turbo) → FIREWORKS_API_KEY

Registers transcribe_audio(file_path, language?) in ctx.tools, allowing agents to analyze audio files, interview recordings, and voice notes directly from disk.

• POST /dsh-voice/transcribe — { dataBase64, mimeType, mode } → { ok, text, provider, tookMs }
• POST /dsh-voice/polish — { text } → { ok, text }
• GET /dsh-voice/status — Returns daemon status, active chains, SenseVoice and realtime config.
• GET /dsh-voice/realtime — WebSocket upgrade for low-latency audio streaming (OpenAI Realtime API / Sherpa-ONNX). Accepts binary audio chunks, returns JSON text deltas.
