Frequently Asked Questions

Everything you need to know about our AI text-to-speech.

Yes, we use the state-of-the-art Kokoro AI models which are specifically designed to provide high-fidelity, human-like speech with natural intonation and emotion.

No. The AI model runs entirely in your browser using WebAssembly. Your text never leaves your device, providing 100% privacy for your content.

You can generate up to 5000 characters at a time. For longer texts, we recommend splitting them into segments for the best performance and audio quality.

AI Text-to-Speech is a technology that converts written text into spoken audio using artificial intelligence. Unlike older robotic voices, modern AI TTS (like our Kokoro models) uses deep learning to understand context and produce natural-sounding speech with correct emphasis and human-like emotional range.

Our tool runs high-performance neural networks directly in your browser using WebAssembly (WASM). When you click generate, your device’s CPU performs the complex calculations required to synthesize audio samples from your text. Because the "brain" of the AI lives in your browser, your text is never uploaded to an external server, ensuring maximum privacy.

Submind provides a professional-grade TTS experience that is completely free and private. It’s perfect for creators who need high-quality voiceovers for videos, accessibility for reading long articles, or simply hearing how their writing sounds. With a curated library of studio voices and on-device processing, it’s the most secure way to generate AI speech.
