Hey Spark
Hey Spark is an always-listening voice assistant desktop application that runs local speech recognition and connects to AI brains.
Hey Spark is an always-listening voice assistant for your laptop that uses a local wake word and runs speech recognition on your CPU. Users can speak commands or questions and hear spoken answers generated by Claude, Hermes Agent, or any OpenAI-compatible model including local options through Ollama. It reaches external tools and systems like GitHub, Gmail, and Calendar through Model Context Protocol servers. Before performing any action that changes data, the assistant asks for a spoken confirmation to ensure safety. The desktop application runs on macOS and Windows, featuring configurable personalities, voices, shortcuts, and connectors.
