dsh-kitt-voice: Voice Interaction Plugin for DeepSeek Harness

`dsh-kitt-voice` is a client-side voice interaction plugin designed specifically for DeepSeek Harness. It supports global hotkeys, multi-page routing, and offline speech synthesis, with features including real-time speech detection, barge-in responses, and multilingual neural voices. The plugin uses a Push-to-Talk mechanism to provide an immersive conversational experience, and supports independent device selection and speech rate adjustment. After installation, a full restart of Harness is required; currently, response text is sent to the cloud for processing.
