Build complete voice apps with Cline

This MCP Server provides the tools to generate speech and modify voices using `tts_bytes` and `voice_changer_bytes`. Cline can fetch these audio streams, write the frontend code to play them, and build a working voice application in your workspace. You don't have to copy-paste API keys or write boilerplate code. Cline handles the entire task, testing the generated audio files and verifying they load correctly.

Clone and localize voices with Cline

The server lets you clone voices and adapt them to new languages using `clone_voice` and `localize_voice`. Cline grabs local audio samples, runs the cloning tools, and saves the resulting voice assets directly into your project. It can also clean up old voice assets using `delete_voice` when you want to refresh your voice library. The agent manages the entire life cycle of your audio assets.

Transcribe and analyze audio files

This toolset processes audio files and extracts text transcripts using `stt_batch` and `list_agent_calls`. Cline can read your local audio recordings, run the batch transcription, and output structured text files. It uses these transcripts to generate summaries or build search indexes. You get fast, accurate transcriptions without leaving your code editor.
