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. ## Key Features - On-device AI inference — no internet required after model download - Two model variants: Base (TTS + voice cloning) and CustomVoice (instruction-based style control) - Real-time performance metrics: RTF, synthesis time, memory usage, token count, and thermal state - Adjustable quality presets: Fast, Balanced, and High - Generation history with built-in audio playback - Record reference audio directly or import from files - Save and manage reference audio library for quick reuse - Dark and Light theme with elegant, minimal interface - Share generated audio files ## How It Works 1. Download a model (~1.9 GB each, one-time) 2. Type your text and tap Generate 3. Listen, share, or save the result ## Requirements - iPhone with Apple Silicon (A17 Pro or later recommended for best performance) - ~2 GB free storage per model Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://www.notion.so/Echovo-App-Page-2fef5511043f80e19a78e09f2d7c9ce3
