⚙️ How It Works
The tool downloads a lightweight Kokoro AI model into your browser. After selecting a voice, it converts text into natural speech locally using CPU or GPU acceleration.
❓ Frequently Asked Questions
Does this text to speech tool work offline?
Yes. After the model is loaded, all speech generation runs locally in your browser without any internet connection.
Is my text sent to a server?
No. Your input stays entirely on your device. This tool performs speech synthesis locally for full privacy.
How realistic are the voices?
The Kokoro model produces high-quality neural voices with natural tone, pacing, and pronunciation.
What is WebGPU and should I use it?
WebGPU enables GPU acceleration in supported browsers, significantly improving performance compared to CPU (WASM).
Why does the model need to download first?
The AI model must be loaded into your browser before generation. This is a one-time download after which it will be cached for future use.
Can I generate long audio files?
Yes, but very long inputs may take more time depending on your device performance.
What voice options are available?
Multiple voices with different accents and quality grades are available. Higher grades typically sound more natural.
What does precision (q8, etc.) mean?
Precision controls model size and performance. Lower precision is faster but slightly less accurate, while higher precision improves quality.
Can I download the generated audio?
Yes. Once generated, you can play and save the audio file directly from your browser.
Is this better than traditional TTS APIs?
This tool prioritizes privacy and offline use, unlike cloud TTS APIs that require network requests and API keys.
Does the Text to Speech (Kokoro) work offline?
Yes, the Text to Speech (Kokoro) is fully functional offline. Because this tool runs entirely in your browser, no data is ever uploaded to external servers. Once the page is loaded, you can seamlessly continue using it without an active internet connection. You can also install Knicknaks as a Progressive Web App (PWA) for native-like offline access.
