Free Text to Speech — Frequently Asked Questions

How does OfflineTTS work?
OfflineTTS runs the Kokoro TTS model (82M parameters) directly in your browser using WebGPU or WebAssembly. Your text never leaves your device — no data is sent to any server.
Is it really free?
Yes, 100% free. The AI model runs on your device, so there are no server costs. The core Kokoro TTS model is Apache 2.0 licensed. No subscriptions, no per-character charges, no hidden fees.
Does it work offline?
After the initial model download (~90MB for Small model, cached in your browser), you can generate speech completely offline — on planes, trains, anywhere. No internet connection required after the first load.
What voices are available?
54 voices across 9 languages including American English, British English, Japanese, Mandarin Chinese, Spanish, French, Hindi, Italian, and Brazilian Portuguese. Top-rated voices include Heart (A quality), Bella (A-), and Emma (B-).
What browsers are supported?
Chrome 113+, Edge 113+, and Safari 17.4+ support WebGPU for fastest performance. All modern browsers support the WASM fallback.
Is OfflineTTS better than ElevenLabs?
OfflineTTS is completely free with no usage limits, works offline, and keeps your data private. ElevenLabs offers more voices and higher quality but charges per character and requires an internet connection. For most use cases — YouTube voiceovers, e-learning, audiobooks — OfflineTTS delivers comparable quality at zero cost.
Can I use generated speech commercially?
Yes. The Kokoro TTS model is Apache 2.0 licensed, which permits commercial use. You can use the generated audio for videos, podcasts, audiobooks, and any commercial project without restrictions.
What audio formats can I export?
You can export audio as WAV (lossless, studio-quality) or MP3 (compressed, smaller file size). WAV is recommended for further audio editing; MP3 is great for direct use in videos and podcasts.
How much text can I convert at once?
Up to 50,000 characters per session. Longer texts are automatically split into chunks and processed sequentially with natural pauses between segments.
Is my text data safe?
Absolutely. All text processing happens locally on your device using WebGPU or WebAssembly. No text is ever sent to any server. Your data stays on your machine — perfect for confidential documents, legal texts, or proprietary content.

Tips for Better Text to Speech Quality

✍️ Punctuate Properly

Commas add short pauses, periods add full stops. Question marks raise pitch at the end. Proper punctuation is the #1 way to improve naturalness.

🎯 Use the Large Model for Best Quality

The Large model (~600MB) produces the most natural-sounding speech. Use Small (~90MB) for quick tests, then switch to Large for production audio.

🔊 Choose the Right Voice

Heart and Bella are rated A/A- for English — warm and expressive. For professional narration, try Emma (British English). Pick voices that match your content style.

⚡ Use WebGPU for Speed

WebGPU generates speech 3–5x faster than the WASM fallback. Chrome 113+ and Edge 113+ support WebGPU. Safari users can use the WASM fallback.
