Is this Norwegian 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 Norwegian 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 (~60 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 Norwegian 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.

Percuma Norwegian Teks ke Ucapan

Norsk

Taip atau tampal teks Norwegian dan dengar ia dibaca - semuanya dalam pelayar anda, tanpa pendaftaran. Model suara dimuat turun sekali (~60 MB) dan disimpan dalam cache secara tempatan, jadi penggunaan seterusnya adalah serta-merta dan berfungsi secara luar talian.

Bagaimana ia berfungsi

1. Taip teks anda
Tampal atau taip sebarang teks Norwegian - tanda baca dan pemecahan baris dikekalkan.
2. Jana
Klik pertama memuat turun model suara ~60 MB ke pelayar anda. Selepas itu, sintesis adalah serta-merta.
3. Muat turun atau mainkan
Mainkan audio secara langsung atau simpan sebagai fail WAV. Audio tidak pernah meninggalkan peranti anda.

Teks anda kekal di peranti anda

Sintesis dijalankan sepenuhnya dalam pelayar anda menggunakan WebAssembly. Satu-satunya permintaan rangkaian adalah untuk mengambil model suara Piper dan runtime ONNX - kedua-duanya adalah aset awam, statik. Kami tidak melihat teks anda dan kami tidak melihat audio yang dihasilkan.

Perlukan suara berkualiti siaran?
