610. OpenClaw Voice Skill

Basic Information

Product Description

The OpenClaw Voice Skill adds voice interaction capabilities to AI agents, including TTS (Text-to-Speech), STT (Speech-to-Text), and Talk Mode (Voice Conversation Mode). By integrating voice AI platforms such as ElevenLabs, Cartesia, and Minimax, OpenClaw agents can not only read out responses but also understand voice input, engage in real-time voice conversations, and even clone specific voices. This elevates OpenClaw from a text-based chat assistant to a fully multimodal voice assistant.
