  • Type: Open-source component (voice interaction feature)
  • Founded: Concurrent with OpenClaw

Product Description

OpenClaw Voice (also known as Talk Mode) is the voice interaction feature of OpenClaw, offering a full-duplex voice interaction experience that integrates three core capabilities: speech-to-text (STT), agent processing, and text-to-speech (TTS). It enables users to engage in hands-free conversations with AI assistants, supporting automatic speech recognition, interruption detection, and expressive speech synthesis.

Technically, TTS utilizes ElevenLabs' streaming API, reducing latency through incremental playback. macOS/iOS defaults to the pcm_44100 format, while Android uses the pcm_24000 format. The architecture adopts a decoupled design: the gateway runs in environments requiring stability (e.g., servers), while the microphone component operates on paired devices (macOS, iOS, Android). This design avoids the issue of forcibly integrating audio hardware into headless servers.

Platform support includes: macOS/iOS supports voice wake word (Voice Wake) + Talk Mode; Android supports continuous voice mode, using ElevenLabs with system TTS as a fallback. The community project VoxClaw extends OpenClaw's voice capabilities, allowing it to speak through any Mac on the network. Some users have implemented fully free AI voice agents by combining models like Minimax.

Core Features/Characteristics

  • Full-duplex voice interaction (Talk Mode)
  • Speech-to-text (STT) integration
  • Text-to-speech (TTS) - ElevenLabs streaming API
  • Voice wake word (Voice Wake)
  • Interruption detection (interrupt-on-speech)
  • Low-latency incremental playback design
  • Multi-platform support (macOS/iOS/Android)
  • Decoupled gateway and microphone architecture
  • VoxClaw network voice extension

Business Model

OpenClaw Voice is free and open-source. ElevenLabs API requires a paid subscription (with a free tier). System TTS serves as a free fallback option.

Target Users

  • Users requiring hands-free operation
  • Users with visual or mobility impairments
  • Users needing AI assistance while driving or exercising
  • Users preferring voice interaction
  • Smart home and IoT scenarios

Competitive Advantages

  • Full-duplex conversation experience (interruptible at any time)
  • Native multi-platform support
  • Flexible architecture (decoupled gateway and microphone)
  • High-quality ElevenLabs speech synthesis
  • Voice wake word support

Market Performance

The Voice feature has received positive feedback from the community. LumaDock published detailed tutorials on TTS/STT/Talk Mode. The community project VoxClaw extended voice capabilities. On LinkedIn, users showcased free voice agent solutions combining Minimax.

Relationship with the OpenClaw Ecosystem

Voice is a crucial component of OpenClaw's multimodal interaction capabilities, expanding OpenClaw from text-only interaction to voice interaction. Together with message channels, Canvas visualization, and other features, it forms OpenClaw's complete interaction layer, covering text, voice, and visual interaction modes.
