Is this Spanish text-to-speech really free?

Yes. The page is public, no signup is required, and there are no credit limits. The voice model runs entirely in your browser. For studio-grade voices and longer narration, see the paid Subformer Voice Synthesis service.

How does the Spanish TTS work in the browser?

It uses Piper, an open-source neural TTS engine, compiled to WebAssembly and run via ONNX Runtime Web. The voice model (~73 MB) is downloaded on first use and cached in your browser's Origin Private File System. Subsequent visits skip the download entirely.

Is my text uploaded to a server?

No. Synthesis runs locally in your browser. The only network calls are to download the Piper voice model and the ONNX runtime - both are static assets. Your text and the generated audio never leave your device.

Does it work offline?

Once the voice model is cached, yes. The first visit needs network access to download the model; after that the page can synthesize speech offline.

What's the difference between this free Spanish TTS and the paid Voice Synthesis service?

The free in-browser TTS uses a medium-quality open-source voice - fine for narration drafts, accessibility, and quick previews, but it sounds noticeably synthetic. The paid Subformer Voice Synthesis service uses studio-grade neural models, supports voice cloning, and produces broadcast-quality audio. Visit /dashboard/voice-synthesis to try it.

Which browsers are supported?

Any modern browser with WebAssembly: Chrome, Firefox, Safari 15+, Edge, and Chromium-based mobile browsers. The page runs ORT in single-threaded mode so it works in every common browser without requiring cross-origin isolation.

Can I download the audio?

Yes. After synthesis you can play the audio inline or click Download to save it as a 22 kHz mono WAV file. Use any audio editor to convert to MP3 or other formats.

Gratis Spanish teks-na-spraak

Español

Tik of plak Spanish teks en hoor dit gespreek - alles in jou blaaier, sonder registrasie. Die stemmodel word een keer afgelaai (~73 MB) en plaaslik gekas, so volgende draaie is onmiddellik en werk offline.

Hoe dit werk

1. Tik jou teks
Plak of tik enige Spanish teks - leestekens en reëlbreuke word gerespekteer.
2. Genereer
Die eerste klik laai die ~73 MB stemmodel na jou blaaier af. Daarna is die sintese onmiddellik.
3. Laai af of speel
Speel die klank inline af of stoor dit as 'n WAV-lêer. Die klank verlaat nooit jou toestel nie.

Jou teks bly op jou toestel

Sintese loop heeltemal in jou blaaier met behulp van WebAssembly. Die enigste netwerkaanvraë is om die Piper-stemmodel en die ONNX-runtime te haal - albei is openbare, statiese hulpbronne. Ons sien nie jou teks nie en ons sien nie die gegenereerde klank nie.
