A voice that knows how to say your product's name
Generic text-to-speech gives itself away on the nouns — your product name, your acronyms, the interface labels. DemoRiff's narration model is tuned specifically for software walkthroughs, and it learns your vocabulary from your own content.

Tuned for product narration
Trained on instructional speech, so it emphasises the verb, pauses before the click, and does not read a UI label like a sentence.
It learns your lexicon
Add product names, acronyms and pronunciations once. Every voice, in every language, respects them from then on.
Cloning with consent
A voice clone requires a spoken consent phrase from the person being cloned, and can be revoked by them at any time.
Two hundred and sixty voices, auditioned on your own script
Browse by language, accent, age, warmth and pace — then hear each candidate read your actual script, not a generic sample. That matters: a voice that sounds great on “the quick brown fox” can fall apart on “configure the SAML assertion mapping.” Shortlist three, put them side by side, and pick.
- Filter by language, accent, timbre, pace and register
- Audition on your real script, not a canned sample
- A/B two voices on the same line, instantly
- Save a house voice per brand kit so the team stays consistent
Your voice, from thirty seconds
Read a short consent passage and the model builds a clone that carries your accent, pace and cadence. It handles your product vocabulary because it was built against your transcripts. From then on you can fix a line by typing it — no re-recording, no matching your energy from three weeks ago, no audible seam where the correction starts.
- 30 seconds of reference audio, 4 minutes for the high-fidelity model
- Spoken consent phrase required and stored with the voice
- Revocable by the voice owner at any time, retroactively
- Clone speaks all 34 languages in your own timbre
Tell it how to read the line
Select any span of the script and direct it: slower here, emphasise this word, pause before the click, sound genuinely pleased rather than performatively pleased. Pronunciation overrides are per-word and per-workspace, so once someone teaches it how to say your company name, nobody has to teach it again.
- Per-span pace, emphasis, pitch and pause control
- Phonetic overrides with IPA or a spoken example
- Workspace pronunciation dictionary, shared across every project
- Automatic timing so narration still lands on the right frame

I am a non-technical founder who sounds, on camera, like a non-technical founder. DemoRiff made my product look like it came out of a company with a marketing department. We closed our seed on that demo.
About voices & cloning
No. Creating a clone requires reading a consent phrase that includes the date and the workspace name, and that recording is stored alongside the voice. Workspace admins can see every clone and who consented to it. The person cloned can revoke at any time, which disables the voice for future renders immediately.
Add it to the workspace pronunciation dictionary once — either with IPA or by recording yourself saying it. Every voice, in every language, uses it from then on, including voices added later.
Yes, and plenty of people do. Studio Sound cleans it up, levels it and removes fillers without replacing your delivery. You can also mix: keep your voice for the main narration and use a synthetic voice for the intro and outro so they stay consistent across a whole series.
