Deng Plus
Highest fidelity
The full-fidelity engine for published work: narration, audiobooks, and anything a listener plays more than once.
- Rendered 24 kHz WAV exports
- Full-length scripts, chapter by chapter
- Provenance sealed on every file
Rega Voice
Text in. A voice out — in the language you think in.
Rega Voice turns a script into speech in Sorani, Iraqi Arabic, Arabic, Turkish, English, Spanish, French, or Chinese — streamed as it renders, sealed with provenance, yours to publish.
Two engines
One tool. Two engines.
Same library, same provenance, same credits — pick the engine that fits the job.
Deng Flash
Streams live
The streaming engine: first audio arrives while the rest of the line is still rendering. Built for previews and live calls.
- Streaming on every plan
- Instant in-App previews
- The same pipeline the agent speaks through
Use it for
One voice tool, five jobs.
Podcasts
Intros, sponsor reads, and full episodes with a cast that stays consistent across a series.
Voiceover
Explainers and ads in eight languages — regenerate one line, not the session.
Audiobooks
Long scripts rendered chapter by chapter, provenance intact across the whole book.
Agents
The same voices answer live calls through Rega Agent, streamed through Deng Flash.
Accessibility
Turn written Kurdish and Arabic into speech for audiences that listen, not read.
Creator and developer
Make it in the App. Ship it over the API.

Rega Voice FAQ.
Which languages can I write in?
Sorani Kurdish, Iraqi Arabic, Arabic, Turkish, English, Spanish, French, and Chinese. Kurdish and Arabic are tuned first.
What is the difference between Deng Plus and Deng Flash?
Fidelity versus latency. Deng Plus renders full-fidelity takes for published work; Deng Flash streams first audio immediately and powers previews and live calls.
Do I need an account to try it?
The demos on this page and in the Labs voice galaxy play without an account. Rendering your own scripts starts with free App credits.
Can I clone my own voice?
Yes, after a verified verbal consent record signed in the App. One clone per account, and the consent stays attached to the voice.
Can I verify the audio afterwards?
Every export carries a C2PA manifest and a ledger claim — verifiable without an account, without trusting us.
