AI Voice Generator
Describe a voice into existence
Write the voice you need in plain language and get back candidates that have never belonged to anyone, free of likeness questions.
Text to speech, cloning and dubbing
Text that sounds like someone meant it.
Most tools hand you a voice and a play button. Sonik gives you the sampling controls behind the model, so you direct the read instead of regenerating and hoping.

Script
Every product has a voice. Sonik makes sure yours sounds like it was recorded in a studio, not generated in a browser tab.

Six ways to make audio. One engine.
Speech is where Sonik starts, not where it stops. Generation, cloning, translation, music and transcription all run on the same research, so a voice you build in one place behaves the same everywhere else.
Text to Speech
Speech you can direct, line by line
Mark up a script with delivery cues, cast a voice from the library, and shape the read with the sampling controls until it lands the way you heard it in your head.
- Delivery cues inline
- Drop [warmly] or [whispers] into the script and the read follows, without splitting the take into fragments.
- A cast, not a dropdown
- Voices carry an accent, a register and a category, so choosing one feels like casting rather than picking option four.
- Reproducible takes
- The parameters that produced a read are stored with it. Reopen any generation and branch from exactly there.
Script
In the ancient land of Eldoria, skies shimmered and forests whispered secrets to the wind. [warmly] There lived a dragon named Zephyros. [whispers] Even the birds fell silent when he passed.

Voice Cloning
Your own voice, on tap
Record a few minutes of clean reference audio and Sonik builds a reusable voice your whole workspace can generate against — the same person, available long after the session ends.
- Minutes, not hours
- A single clean take is enough. No studio booking, no reading a phonetic script for an afternoon.
- Shared across the workspace
- Once a voice exists, everyone on the team generates against it, so the brand keeps one voice instead of six.
- Consent recorded with the voice
- Permission is captured when the voice is created and stays attached to it, so provenance is never a question later.
You need the speaker's permission to clone their voice. We ask you to confirm it every time.

Dubbing
Carry a performance across languages
Keep the timing, emphasis and character of the original take while the words change. The same performer, in every language you ship — so a dub stops sounding like a dub.
- The performance travels
- Pacing and emphasis carry over, instead of being flattened into a neutral read in the target language.
- One voice, many markets
- Queue every language you need from a single take and collect the finished audio as each one lands.
- Timed to the original
- Lines stay aligned to the source, so dubbed audio drops back onto the existing edit without a re-cut.

So the launch moved to the ninth?

It did. Marketing wanted the extra week.

Then let's cut the demo down to two minutes.
Speech to Text
Transcripts that know who spoke
Word-level timings and speaker labels, so a recording becomes something you can search, caption and cut against.
Direct the performance
Sampling controls exposed on every generation, not buried behind a preset.
Nothing is ever lost
Every take is stored with the text and parameters that produced it.
Built for teams, not seats
Workspaces scope voices, history and billing to the organisation.
The same engine over HTTP
Everything the dashboard does is available as an API you can ship on.
The controls
Direct the read, don't reroll it
These are the same four parameters the app exposes on every generation. Drag them to see how much of the performance is actually under your hand.
An illustration, not a live generation
0.7
How much the delivery is allowed to vary from the safest read.
0.9
Trims the long tail of unlikely acoustic choices.
50
Caps how many candidates the sampler considers per step.
1.2
Discourages the flat, looping cadence long scripts drift into.
The library
Meet the cast
Every voice carries an accent, a register and a category, so you search the library the way a casting director would. Pick one and it loads into the player above.
How it works
Script in, finished audio out
Three steps from a blank page to a file you can ship, whether that is a single ad read or a back catalogue of audiobooks.
01
Choose or clone a voice
Start from the curated library, or upload a reference take and make the voice your own.
02
Write and direct
Paste the script, then shape delivery with the generation controls until the read lands.
03
Ship the audio
Download the file, or call the same generation from your product over the API.
Responsibility
Safety, built in
Synthetic voice is only useful if people can trust what they are hearing. These are commitments we design against, not features bolted on afterwards.
Consent
A cloned voice needs the speaker's permission. We ask you to confirm it, and we keep the record attached to the voice.
Provenance
Generated audio should be identifiable as generated. Every file Sonik produces stays traceable back to the generation that made it.
Accountability
Workspaces are auditable. Voices, takes and the people who made them are attributable long after the session ends.

Questions
Before you sign up
The things people ask us most often, answered without the marketing gloss.
Most APIs give you a voice and a play button. Sonik exposes the sampling parameters behind the model, so you can direct the delivery the way you would direct a session musician, then keep the exact settings that worked.
Yes on the Producer plan and above. The free Studio plan is intended for evaluation and personal projects.
A few minutes of clean, single-speaker audio with no music or background noise. You need the rights or explicit consent to use the voice you upload.
Generations are written to object storage scoped to your workspace, and served through short-lived signed URLs. Deleting a generation removes the underlying file.
Yes. Generation, the voice library and history are all available over HTTP, and the dashboard is built on the same endpoints your integration would call.
A typical paragraph returns in a few seconds. Longer scripts stream progress, and Producer workspaces run on a priority queue.
Hear your own script in about ten seconds.
Sign up, paste a paragraph, pick a voice. The free tier is enough to know whether Sonik belongs in your pipeline.
