+# Speech AI MCP Server
+
+An MCP server that provides pronunciation assessment, speech-to-text, and text-to-speech capabilities for AI agents. Built for language learning, accessibility, and voice applications.
+
+## Features
+
+- **Pronunciation Assessment**: Score English pronunciation at phoneme, word, and sentence level (0-100). 17MB model, <300ms latency. Exceeds human expert accuracy.
+- **Speech-to-Text (STT)**: Transcribe audio with word-level timestamps and confidence scores.
+- **Text-to-Speech (TTS)**: Generate natural speech with 12 English voices (US + UK accents). Ranked #1 on TTS Arena.
