OpenVoiceUI

A plug-and-play browser-based voice agent platform. Connect any LLM, any TTS provider, and any AI framework — with a built-in music player, AI music generation, and a live web canvas display system.

Hosting notice: OpenVoiceUI is designed to run on a dedicated VPS (see Hetzner setup below). Running it on a local machine is possible but not recommended — microphone access, SSL, and persistent uptime all work significantly better on a hosted server. For the best experience, deploy to a VPS before using it seriously.

What It Is

OpenVoiceUI is a modular voice UI shell. You bring the intelligence (LLM + TTS), it handles everything else:

• Voice I/O — browser-based STT with push-to-talk, wake words, or continuous mode
• Animated Faces — multiple face modes (eye-face avatar, halo smoke orb) with mood states, thinking animations, and audio-reactive waveform mouth
• Web Canvas — fullscreen iframe display system for AI-generated HTML pages, dashboards, and reports with interactive links, page versioning, and external URL display
• Desktop OS Interface — full desktop-like canvas experience with right-click context menus, wallpaper upload, trash, shortcuts, and folder creation (auto-seeded as default pages)
• Music Player — background music with crossfade, AI ducking, and AI trigger commands
• Music Generation — AI-generated track support via Suno or fal.ai integrations
• AI Image Generation — HuggingFace-powered image generation with FLUX.1 and SD3.5 models, quality presets, and aspect ratio control
• Voice Cloning — clone and generate speech with custom voice embeddings via fal.ai Qwen3-TTS
• Soundboard — configurable sound effects with text-trigger detection
• Agent Profiles — switch personas/providers without restart via JSON config
• Agent Activity Chip — live action ticker showing what the agent is doing in real-time
• Live Instruction Editor — hot-reload system prompt from the admin panel
• Admin Dashboard — session control, playlist editor, face picker, theme editor
• Issue Reporter — in-app bug/feedback reporting modal with session context (development tool)
• Server-Side Settings — voice, face, and TTS preferences persist across devices via server (no localStorage)
• Document Upload Extraction — PDF and document text extraction from uploads
• Empty Response Auto-Recovery — auto-retry on empty LLM responses with Z.AI direct fallback and session auto-recovery

Open Framework Philosophy

OpenVoiceUI is built as an open voice UI shell — it doesn't lock you into any specific LLM, TTS engine, STT provider, or AI framework. Every layer is a pluggable slot. Drop in a gateway plugin, a TTS provider, or a custom adapter and it just works. The built-in providers are defaults, not requirements.

LLM / Gateway Providers

Connect to any LLM via a gateway plugin — OpenClaw is built-in, others are drop-in:

| Provider | Status | |----------|--------| | Any OpenClaw-compatible gateway | Built-in | | Z.AI (GLM models) | Built-in | | OpenAI-compatible APIs | Via adapter | | Ollama (local) | Via adapter | | Hume EVI | Built-in adapter | | LangChain, AutoGen, custom agent framework | Via gateway plugin | | Any LLM or framework you build a plugin for | Drop a folder in plugins/ |

TTS Providers

| Provider | Type | Cost | |----------|------|------| | Supertonic | Local ONNX | Free | | Groq Orpheus | Cloud, fast | ~$0.05/min | | Qwen3-TTS | Cloud, expressive | ~$0.003/min | | Hume EVI | Cloud, emotion-aware | ~$0.032/min | | Any TTS engine you implement | Local or cloud | Your choice |

STT Providers

| Provider | Type | Cost | Notes | |----------|------|------|-------| | Web Speech API | Browser-native | Free | No API key needed, Chrome/Edge only | | Deepgram Nova-2 | Cloud streaming | Pay-per-use | Reliable paid alternative, real-time WebSocket streaming | | Groq Whisper | Cloud batch | Free tier available | Fast batch transcription via Groq API | | Whisper | Local | Free | Self-hosted Whisper model | | Hume EVI | Cloud, full-duplex | ~$0.032/min | Emotion-aware, bidirectional | | Any STT provider | Via custom adapter | Your choice | Implement the STT adapter interface |

Features

Voice Modes

• Continuous — always listening, silence timeout triggers send
• Push-to-Talk — hold button or configurable hotkey (keyboard/mouse)
• Listen — passive monitoring mode
• Sleep — goodbye detection pauses the agent, wake word reactivates
• Agent-to-Agent — A2A communication panel

Canvas System

• AI can open and display any HTML page in a fullscreen overlay
• Manifest-based page discovery with search, categories, and starred pages
• Triggered via [CANVAS:page-id] tags in AI responses
• Real-time SSE updates from server
• Interactive links — canvas pages communicate with the app via postMessage bridge (navigate, speak, open URLs)
• Page versioning — automatic .versions/ backup on every change with restore API
• External URL display — load any URL in the canvas iframe via [CANVAS_URL:https://...]
• Default pages — desktop OS and file explorer pages auto-seeded on startup
• Admin lock/URL columns — admin panel shows lock state and copyable URLs for each page
• Padded mode — configurable edge padding on canvas pages
• Error auto-injection — canvas pages get an error bridge for debugging in the ActionConsole
• Content Security Policy — restrictive CSP on canvas pages to prevent XSS

STT Improvements

• Hallucination filter — rejects ghost transcripts from silence
• Noise rejection — sustained speech detection prevents spurious triggers
• VAD tuning — configurable voice activity detection thresholds

Music Player

• Background playlist with crossfade (1.5s smooth transitions)
• Auto-ducking during TTS (volume drops, restores after)
• AI voice commands: play, stop, skip, volume up/down
• Generated tracks (AI-composed) + custom playlists
• Track history (back button, 20-track buffer)

Profile System

Define agents in JSON — each profile configures:

• LLM provider, model, parameters
• TTS voice, speed, parallel sentence mode
• STT silence timeout, PTT mode, wake words
• UI theme, face mood, enabled features
• Session key strategy

Security

• Content Security Policy — restrictive CSP headers on canvas pages to prevent XSS
• SSRF protection — all external fetch endpoints validate and block internal network requests
• Path traversal protection — file access endpoints sanitize paths
• WebSocket authentication — gateway WebSocket connections require valid auth tokens

Prerequisites

• OpenClaw gateway 2026.3.13 — openclaw.ai · version requirements
• Groq API key for TTS — console.groq.com (free tier available)
• Optional: Suno API key (music generation), Clerk (auth for multi-user deployments)

OpenVoiceUI is tested with [email protected]. The Docker setup installs this version automatically. If you're using an existing OpenClaw install, see OpenClaw Requirements — other versions may have breaking changes that prevent voice conversations from working.

Installation

Option 1: Pinokio One-Click Install

The easiest way to get started. Pinokio is a free app manager that handles installation, startup, and updates automatically.

1. Install Pinokio if you don't have it
2. Search for "OpenVoiceUI" in the Pinokio app store, or add this repo URL directly
3. Click Install — Pinokio will clone the repo, build Docker images, and run onboarding
4. Click Start to launch all services
5. Open the URL shown in Pinokio to access the UI

Pinokio handles Docker Compose orchestration, environment configuration, and service lifecycle. Use the Stop button to shut down, and Update to pull the latest changes.

Option 2: Deployment (Recommended: VPS)

The recommended way to run OpenVoiceUI is on a dedicated VPS — microphone access, SSL, and always-on uptime all work significantly better hosted than on a local machine.

A setup script handles nginx, Let's Encrypt SSL, and systemd automatically:

git clone https://github.com/MCERQUA/OpenVoiceUI
cd OpenVoiceUI
cp .env.example .env
# Edit .env — set CLAWDBOT_AUTH_TOKEN and GROQ_API_KEY at minimum
# Edit deploy/setup-sudo.sh — set DOMAIN, PORT, EMAIL, INSTALL_DIR at the top
sudo bash deploy/setup-sudo.sh

The script is idempotent — safe to re-run. Skips SSL if cert already exists.

sudo systemctl status openvoiceui
sudo journalctl -u openvoiceui -f

Option 3: Local Install (Docker)

Docker is the easiest path for local development — it runs OpenClaw, Supertonic TTS, and OpenVoiceUI together. Note that browser microphone access requires HTTPS — on localhost Chrome/Edge will still allow it, but other devices on your network won't work without a cert.

git clone https://github.com/MCERQUA/OpenVoiceUI
cd OpenVoiceUI
cp .env.example .env

Step 1: Onboard OpenClaw (one-time)

Run the interactive onboarding wizard to configure your LLM provider and generate an auth token:

docker compose build openclaw
docker compose run --rm openclaw openclaw onboard

This will prompt you to choose an LLM provider (Anthropic, OpenAI, etc.), enter your API key, and generate a gateway auth token.

Step 2: Configure .env

Set the auth token from onboarding:

PORT=5001
CLAWDBOT_AUTH_TOKEN=<token-from-onboarding>

CLAWDBOT_GATEWAY_URL does not need to be set — Docker Compose automatically routes to the OpenClaw container via loopback networking. TTS works out of the box with Supertonic (local, free). Optionally add GROQ_API_KEY for Groq Orpheus TTS.

Step 3: Start

docker compose up --build

Open http://localhost:5001 in your browser.

How it works

The docker-compose.yml runs three services:

| Service | Description | |---------|-------------| | openclaw | OpenClaw gateway (Node.js) — handles LLM routing, tool use, and agent sessions on port 18791 | | supertonic | Local TTS engine (ONNX) — provides free text-to-speech without external API keys | | openvoiceui | OpenVoiceUI server (Python/Flask) — serves the frontend and connects to OpenClaw and Supertonic |

OpenClaw config is persisted in a Docker volume (openclaw-data), so onboarding only needs to run once.

Option 4: VS Code Dev Container

For contributors and developers, OpenVoiceUI includes a VS Code dev container configuration that sets up the full development environment automatically.

1. Install the Dev Containers extension in VS Code
2. Open the repo folder in VS Code
3. When prompted, click Reopen in Container (or run the "Dev Containers: Reopen in Container" command)
4. VS Code will build and start all services using .devcontainer/docker-compose.devcontainer.yml
5. The development server starts automatically with hot-reload

The dev container includes all dependencies pre-installed and is configured for the full Docker Compose stack.

TTS setup

Supertonic (local, free) is included and works out of the box — select "supertonic" as the TTS provider in the Settings panel.

To use Groq Orpheus TTS instead, you must first accept the model terms at console.groq.com/playground?model=canopylabs%2Forpheus-v1-english, then set GROQ_API_KEY in .env.

Authentication

Auth is opt-in. By default, OpenVoiceUI runs with no authentication — all endpoints are accessible. This is the right setting for self-hosted single-user deployments.

To enable Clerk JWT auth (for multi-user or public-facing deployments):

1. Create a Clerk app at clerk.com
2. Add CLERK_PUBLISHABLE_KEY=pk_live_... to .env
3. Set CANVAS_REQUIRE_AUTH=true in .env
4. Set ALLOWED_USER_IDS=user_yourclerkid — find your user ID in server logs after first login

OpenClaw Integration

OpenVoiceUI connects to an OpenClaw gateway via persistent WebSocket. OpenClaw handles LLM routing, tool use, and agent sessions.

OpenClaw >= 2026.2.24: Requires Ed25519 device identity signing. OpenVoiceUI handles this automatically — a .device-identity.json file is generated on first run (never committed to git). The gateway auto-approves local loopback clients on first connect.

Without a configured gateway: The frontend will load but /api/conversation calls will fail. OpenClaw is the default — or drop in any gateway plugin as a replacement.

Version compatibility: OpenVoiceUI is tested against [email protected] and performs a compatibility check on startup. A protocol compatibility layer handles differences between versions automatically. See OpenClaw Requirements for details on supported versions and known breaking changes.

Personalizing Your Agent

Edit profiles/default.json to configure your agent:

{
  "name": "My Assistant",
  "system_prompt": "You are a helpful voice assistant...",
  "llm": { "provider": "gateway", "model": "glm-4.7" },
  "voice": { "tts_provider": "groq", "voice_id": "tara" },
  "features": { "canvas": true, "music": true, "tools": true }
}

Edit prompts/voice-system-prompt.md to change the system prompt — changes are hot-reloaded with no restart.

Building an Adapter

To connect a new LLM or voice framework, use src/adapters/_template.js as a starting point. Built-in adapters include ClawdBot (OpenClaw), Hume EVI, ElevenLabs Classic, and ElevenLabs Hybrid. Adapters implement a simple interface:

export class MyAdapter {
  async init(bridge, config) { ... }
  async start() { ... }
  async stop() { ... }
  async destroy() { ... }
}

Register it in src/shell/adapter-registry.js and reference it in your profile JSON.

Gateway Plugins

The backend uses a plugin system for LLM gateways. Drop a folder into plugins/, restart — it's live.

plugins/
  my-gateway/
    plugin.json   <- manifest (id, provides, requires_env)
    gateway.py    <- class Gateway(GatewayBase)

plugin.json:

{
  "id": "my-gateway",
  "provides": "gateway",
  "gateway_class": "Gateway",
  "requires_env": ["MY_API_KEY"]
}

gateway.py subclasses services.gateways.base.GatewayBase and implements stream_to_queue().

To route a profile to your gateway, add gateway_id to its adapter_config:

"adapter_config": { "gateway_id": "my-gateway", "sessionKey": "my-1" }

Gateways can also call each other for inter-agent delegation:

from services.gateway_manager import gateway_manager
result = gateway_manager.ask("openclaw", "Summarise this: " + text, session_key)

Full guide: plugins/README.md

Skill Runner Service

The deploy/skill-runner/ directory contains a shared skill execution service. This is a lightweight Python server that can execute agent skills in an isolated environment, providing a common runtime for skill definitions that need server-side execution (file I/O, API calls, data processing).

Build and run alongside the main stack:

docker compose build skill-runner
docker compose up -d skill-runner

Hosting Multiple Users (Hetzner VPS)

OpenVoiceUI is designed so you can host a single VPS and serve multiple clients, each with their own voice agent instance.

Recommended workflow:

1. Set up your base account — install OpenVoiceUI on a Hetzner VPS under a base Linux user. Configure all API keys in .env. Verify everything works.

2. For each new client, create a new Linux user on the same VPS:

   adduser clientname
   cp -r /home/base/OpenVoiceUI /home/clientname/OpenVoiceUI
   chown -R clientname:clientname /home/clientname/OpenVoiceUI

3. Edit their .env with their API keys and a unique port:

   PORT=15004          # different port per user
   CLAWDBOT_AUTH_TOKEN=their-openclaw-token
   GROQ_API_KEY=their-groq-key

4. Run setup-sudo.sh for their domain — creates systemd service, nginx vhost, and SSL cert automatically.

5. Each client gets their own domain, their own agent session, and their own canvas/music library.

Quick server requirements:

• Ubuntu 22.04+
• Nginx + Certbot (Let's Encrypt)
• Python 3.10+, venv per user

Development Notes

Issue Reporter (temporary): The in-app issue reporting button in the toolbar is a temporary development tool included during the active development phase to help capture bugs with session context. It will be removed or made optional before a stable release.
