Powering voices for teams at
Cloning is the easy part. Resona gives you the controls a director actually needs: emotion, pacing, pronunciation, and consistency across thousands of lines.
Upload 30 seconds of clean audio and get a production-ready clone that preserves accent, timbre, and breathing patterns. Add up to 30 minutes of samples for a high-fidelity professional clone that holds up across long-form narration.
Tag any sentence with whispered, furious, deadpan, joyful, or 40+ other deliveries. Blend emotions with intensity sliders and keyframe shifts mid-sentence, the way a director would coach a real actor.
Your cloned voice speaks Spanish, Japanese, Hindi, and 38 more languages while staying unmistakably you. Lip-sync timing export included.
Lock brand names, character names, and jargon to exact phonetics once. Every future generation respects it, project-wide.
Stream speech at under 180ms latency for agents, IVR, and game NPCs. SDKs for Python, Node, Unity, and Unreal.
Generate four distinct takes per line and pick the read you like, exactly like a recording session. Mark favorites and Resona learns your taste for the rest of the script.
Every file carries an inaudible cryptographic watermark plus C2PA content credentials, so your audience and your legal team can verify what is synthetic and who authorized it.
No audio engineering background needed. If you can write a script, you can direct a session.
Read our 30-second consent script into any mic, or upload existing recordings. Resona cleans noise, levels volume, and verifies the speaker's consent signature automatically.
Our v3 model maps the voice's fingerprint: pitch contour, vowel color, rhythm, even the way it trails off at sentence ends. You get a preview line to approve before anything is saved.
Paste your script, tag emotions, tweak pacing per line, and export WAV, MP3, or timed SRT-aligned stems straight into your DAW, game engine, or video editor.
Teams use Resona anywhere a human voice used to be the bottleneck.
Voice 10,000 NPC lines without booking 10,000 studio hours. Iterate on scripts up to ship day.
Narrate a full-length novel in your author's own voice over a weekend, with chapter-level emotion arcs.
Localize features and trailers into 41 languages while keeping the original actor's performance.
Update course narration in minutes when content changes, instead of re-recording entire modules.
Test 20 voiceover variants per creative, then scale the winner across regions in the same brand voice.
Give your support bot a consistent, branded voice with sub-200ms streaming responses.
Fix flubbed lines by typing the correction. Your edit is indistinguishable from the original take.
Preserve the voices of people facing speech loss, so they can keep speaking as themselves.
Voice cloning without consent is impersonation, full stop. Resona is built so the right voices get cloned and the wrong ones cannot be.
Trust by the numbers
"We voiced 14,000 lines of side-quest dialogue across six character clones. Our audio director now spends her time directing performances instead of chasing studio bookings."
"I cloned my own voice for my back catalog of 11 audiobooks. Listeners genuinely cannot tell the chapters apart, and I finished in nine days instead of nine months."
"The realtime API replaced our robotic IVR voice with our actual brand spokesperson, with her enthusiastic sign-off. CSAT on phone support jumped eight points in a quarter."
Every plan includes consent verification, watermarking, and commercial usage rights.
For trying real projects, not just demos.
For podcasters, authors, and indie game teams.
For studios shipping at broadcast scale.
Need millions of characters or on-prem deployment? Enterprise plans include custom model hosting and contractual voice exclusivity.
Instant clones need just 30 seconds of clean speech. For long-form work like audiobooks, professional clones trained on 10 to 30 minutes of audio capture finer details: breath placement, sibilance, and how the voice changes across emotional registers.
Only with their verified consent. The speaker must record our consent phrase, and our verification model confirms it matches the training sample. Voices on our no-clone registry, including public figures, are blocked at the model level regardless of what audio you upload.
Yes. All paid plans include full commercial rights to your generated audio, including broadcast, streaming, and paid advertising. The free plan requires attribution. Your voiceprint itself always remains your property and is deletable at any time.
In blind tests, listeners identified Resona v3 professional clones as synthetic only 52% of the time, statistically a coin flip. Quality depends heavily on your sample: a quiet room and a decent mic matter more than expensive gear.
Your voiceprints and samples are permanently deleted 30 days after cancellation, or immediately if you request it. We never use customer voiceprints to train shared models, and we have never sold voice data. That is contractual, not just a policy page.
Yes. The streaming endpoint delivers first audio in under 180ms and supports word-level interruption, which makes it suitable for voice agents, live IVR, and in-game NPCs. SDKs are available for Python, Node.js, Unity, and Unreal Engine, with WebSocket access for everything else.
