+# EchoPlex: Your Agent's Voice
+
+**Track:** MCP Tool / Server
+
+### Unleashing the Voice of AI Agents
+
+Language models are powerful, but they are trapped in a world of text. `EchoPlex` shatters this limitation. It is a state-of-the-art, MCP-enabled voice synthesis tool that allows any AI agent to speak.
+
+By leveraging the power of Coqui's XTTS-v2 model, `EchoPlex` provides high-quality, multi-lingual voice cloning. An AI agent can now do more than just write; it can narrate stories, provide vocal feedback, read audiobooks, or adopt a specific persona with a unique voice.
+
+### How it Works as an MCP Tool
+
+`EchoPlex` is designed as a seamless MCP server. An agent can call this tool with a block of text, a reference voice audio, and desired emotional tone parameters. `EchoPlex` handles the complex synthesis process and returns a high-fidelity audio output.
+
+**Example Agent Instruction:** *"Read the following summary of the article 'The Future of AI' in a professional and engaging British voice."*
+
+The agent would simply pass the text and a reference audio URL to `EchoPlex` to get the job done.
+
+### Key Features:
+
+*   **MCP-Native:** Built from the ground up to serve as a tool for the next generation of AI agents.
+*   **High-Fidelity Voice Cloning:** Utilizes the advanced XTTS-v2 model for realistic and natural-sounding voices.
+*   **Advanced Text Pre-processing:** A sophisticated text analysis and cleaning pipeline ensures high-quality pronunciation, handling numbers, special characters, and language-specific nuances.
+*   **Fine-Grained Control:** Tweak temperature, speed, and other parameters to control the speech's tone and style.
+*   **Multi-Lingual Support:** Ready to give a voice to agents speaking multiple languages.
