dsh-hold-to-talk: Local Hold-to-Talk Voice Input for the DeepSeek Harness Web Input Field

dsh-hold-to-talk is a local, offline voice input plugin for the DeepSeek Harness Web composer. It replicates WeChat’s “hold-to-talk” interaction by invoking the SenseVoice model in the browser, requiring no API key and keeping all audio processing local. The plugin supports long-press recording, real-time preview, swipe-up cancellation, and automatic completion; when recording ends, the transcribed text is automatically inserted into the draft. The initial use requires downloading a model of approximately 230 MB. It requires a Chromium-based browser and a Node.js runtime, making it suitable for privacy- and data-security-focused local deployment scenarios.
