Echovo - Best TTS & Voice Cloning

Echovo brings state-of-the-art text-to-speech right to your iPhone, powered by Qwen3-TTS running entirely on-device with Apple silicon acceleration.
Your text never leaves your phone.

## Two Powerful Modes

- **Text-to-Speech**: Type or paste any text and generate natural, expressive speech. Choose from multiple speakers, adjust quality settings, and control the speaking style with custom instructions.
- **Voice Clone**: Record a short audio clip or upload a reference file, and Echovo will generate speech that matches the voice characteristics. Clone any voice in seconds.

## 11 Languages Supported

Generate speech in English, Chinese, Japanese, Korean, German, French, Spanish, Russian, Portuguese, Italian — or let auto-detection handle it for you.

## Completely Private

All processing happens on your device using Apple's MLX framework. No audio data, no text, and no voice samples are ever sent to external servers. Your conversations stay yours.
