Soniox voice cloning

Create a high-fidelity digital replica of your voice, capturing the details that make every speaker unique: tone, emotion, rhythm, accent, pacing, pronunciation, delivery, and vocal personality.

Voice cloning in 60+ languages

Soniox supports voice cloning across all 60+ languages, not just English or a small set of selected languages. Our models capture the rhythm, pronunciation, accent, tone, and vocal character of each speaker in each language.

Voice cloning for every domain

Generate natural cloned speech for any domain, from voice agents and media production to healthcare, finance, legal, support, and enterprise workflows, including IDs, numbers, addresses, names, acronyms, product terms, and specialized vocabulary.

Built for production scale

Soniox voice cloning is built for real-world production, from low-latency voice agents to high-volume content generation. Generate natural cloned speech reliably at scale, with pricing designed for large deployments.

Technology

Soniox voice cloning is built on advanced speech AI trained to understand the full complexity of human voice, not just words, but tone, rhythm, accent, pacing, pronunciation, emotion, and vocal personality.

Our models capture the fine details that make each speaker unique and reproduce them with high fidelity across languages, domains, and speaking styles. The result is natural, expressive cloned speech that sounds realistic, consistent, and production-ready.

How Soniox voice cloning works

Create a natural AI voice from a short audio sample and generate speech from text in the cloned voice.

1

Upload or record a voice sample

Provide a clear sample of the voice you want to clone. Soniox uses it to learn the speaker's vocal identity.

2

Soniox captures the voice

Our speech AI analyzes the speaker's tone, rhythm, accent, pacing, pronunciation, emotion, and delivery.

3

Generate cloned speech

Enter text and generate natural speech in the cloned voice for voice agents, voiceovers, podcasts, audiobooks, ads, games, and more.

Use cases

Voice agents

Give AI agents a natural, consistent voice that sounds human and responds with low latency. Build voice experiences that feel personal, expressive, and on-brand.

Audiobooks and narration

Create high-quality long-form narration with a consistent voice, tone, and delivery. Ideal for audiobooks, education, training, and spoken media.

Podcasts

Produce and edit spoken content faster. Generate new segments, correct mistakes, localize episodes, or create full narration while keeping the original voice.

Video voiceovers

Generate voiceovers for product videos, YouTube, social media, courses, tutorials, and marketing campaigns with a consistent speaker identity.

Games and interactive characters

Create lifelike character voices at scale for NPCs, protagonists, virtual companions, and interactive experiences.

Advertising and localization

Produce campaigns across markets while preserving the same recognizable brand voice. Generate natural speech in different languages without re-recording every version.

Frequently asked questions

How much audio does Soniox need to clone a voice?
Soniox clones a voice from a short reference clip, from a few seconds up to 20 seconds. Use a clean recording of a single speaker with little background noise, up to 10 MB, and keep the tone and audio quality consistent throughout, since the model reproduces whatever it hears. The better the input sample, the better the cloned voice, so a clean and consistent clip produces the most faithful result. Processing is quick, and the voice is usually ready to use within seconds.
Which languages does voice cloning support?
A cloned voice works across all 60+ supported languages, the same as a built-in Soniox voice, and keeps a consistent identity even when the text switches languages mid-sentence. The model reproduces the speaker's rhythm, pronunciation, accent, and tone in each language.
What can I use a cloned voice for?
You can generate cloned speech for voice agents, voiceovers, ads, podcasts, audiobooks, and games, as well as production workflows in domains like healthcare, finance, legal, and support. A cloned voice can be used anywhere a built-in Soniox voice is accepted.
Does the cloned voice keep the speaker's accent and delivery?
Yes. Soniox captures tone, emotion, rhythm, accent, pacing, pronunciation, and delivery, so the voice keeps the character of the original speaker instead of sounding generic. The model mimics everything in the reference clip, down to inflection and breathing, so a clean and consistent clip gives the most faithful result.
How do I use a cloned voice in my application?
Once the voice is ready, reference it by its voice ID, in the same place you would pass a built-in voice name. It works with both the real-time WebSocket API and the REST API, across all 60+ languages. Create, manage, and recompute voices in the Soniox Console or with the voice API.
Who is responsible for the voices I clone?
Soniox voice cloning is built for production use with voices you own or have a license or explicit permission to use. You are responsible and liable for the voices you clone and the speech you generate, including holding the rights and consent required to use them. Cloning a person without permission, or using a cloned voice to impersonate or deceive, is a violation of the Soniox terms.
Is voice cloning ready for production scale?
Yes. Soniox voice cloning is built for real-world production, from low-latency voice agents to high-volume content generation. It runs through the same real-time and REST APIs as built-in voices, with pricing designed for large deployments.
How do I get started?
Create a voice in the Soniox Console under Voices, or with the voice API, by uploading a short reference clip. Once it is ready, generate speech from text using the voice ID. See the documentation to start building.
