How to pick a voice that fits

Thirty-eight voices is a lot. The quickest way to choose is to ignore the names and use your ears. Here is a method that works.

  1. Narrow it down by type

    Use the All, Female and Male filters in the Studio, or the accent filters on the standard voices page. Decide US or UK first, because that choice changes the feel the most.

    Filter the voices, press play to hear one, and pick it.
  2. Listen to three

    Play the sample of three voices in a row. Do not decide yet. Notice which one you can listen to for two minutes without getting tired of it.

  3. Test it on your own words

    Samples are one sentence. Your script is not. Generate the first lines of your real script before you commit.

Eight voices, eight jobs

On the Clonylab home page, eight voices are shown doing a job each. These are examples, not rules. Any voice can read any script.

Eight voices shown on the home page and the job each one is demonstrated for
VoiceTypeShown doing
HeartUS femaleA YouTube intro
MichaelUS maleAn advert
EmmaUK femaleAn audiobook
SarahUS femaleAn online course
OnyxUS maleA podcast intro
SkyUS femaleA product explainer
GeorgeUK maleA documentary
AdamUS maleA training video

Names like Alloy, Echo, Fable, Onyx and Nova, and Aoede, Kore, Puck and Fenrir, also appear in other products. The Clonylab voices with those names are different voices, so do not expect them to sound the same.

What makes the voices different under the hood

The 38 voices come from two open voice engines, and you will see the difference in how they are labeled.

The two voice engines in Clonylab
EngineVoicesHow they are labeled
Kokoro28 named voices: 11 US female, 9 US male, 4 UK female and 4 UK maleBy first name, with the accent and a download size
Piper10 neutral voices: 8 US and 2 UK (Cori)By name, with a quality level of medium or high

You do not need to care about the engine to use the voices. It is useful to know that “neutral” voices come from Piper, and that the Studio shows each voice’s download size, which differs by voice.

And a voice that is yours

Standard voices are shared by everyone. A cloned voice is yours. Record about 10 seconds, confirm it is your voice, and the Studio adds it under Cloned, next to the standard voices. You can mix them in one script by using a voice tag, such as [Adam], to switch the speaker from that point on.

Read the whole flow on the voice clone online page. On the free plan you can clone up to 3 voices.

What people make with an AI voice generator

Things to make with the AI voice generator
UseWhat you writeA good place to start
Video voice-overA narration or a how-toA clear US or UK voice and a steady speed
Podcast introsA 20-second welcomeA voice with a character, plus a short [pause 1s]
Training and coursesLesson scriptsA voice you can listen to for long stretches

Audiobook draftsA chapterA voice you like, with slower pace tags

Add pauses and style tags to direct the reading. The AI voiceover generator page shows how.

Three auditions to run before you choose

Samples tell you how a voice sounds in a single sentence. These three auditions tell you how it behaves in your work.

Three auditions for choosing an AI voice
AuditionWhat to pasteWhy it helps
The opening lineThe first sentence of your real scriptFirst impressions decide whether people keep listening
The hard lineA sentence with numbers, a name or a long clauseShows how a voice handles difficult text
The long readA full paragraph, if your plan allows itShows whether you can listen to it for minutes

On the free plan, use your 300 characters for the first two. Pro lets you run all three as often as you like.

Mixing voices in one script

You are not tied to one voice per file. Write a voice name in square brackets, and that voice speaks from there until you name another. That is how you make a short dialogue.

[Adam] Did you hear the new update? [pause 500ms] [Emma] I did. It’s faster than before.

Both voices need to be available to you. The standard voices always are, and your cloned voices work too. The AI voiceover generator page explains more of the tags.

Five common mistakes when choosing a voice

  • Picking by name. The names mean nothing. Pick by ear.
  • Deciding on one sentence. Test your own text.
  • Mixing accents without meaning to. US and UK voices side by side can feel like a mistake.
  • Ignoring the download. The Studio shows each voice’s size, and the first use downloads it.
  • Forgetting your own voice. If your content should sound like you, a clone beats every premade voice.

And if you need the licence picture for business use, text to speech for commercial use covers it.

Where you pick and use voices

Voices show up in three places, and each one answers a different question.

What “female”, “male” and “neutral” mean here

Clonylab labels each voice as female, male or neutral. Female and male voices come from the Kokoro engine. Neutral voices come from the Piper engine, which does not tag a voice as female or male.

If you want a voice that does not lean either way, start with the neutral list. If you are not sure, press play on a few from each group.

Questions about the AI voice generator

What is an AI voice generator?

A tool that turns text into spoken audio in a synthetic voice. Clonylab’s generator makes English voice-overs in 38 premade voices or in your own cloned voice.

How many voices does Clonylab have?

38 standard English voices: 28 US and 10 UK, in female, male and neutral. You can add voices you clone yourself.

Can I hear the voices before signing up?

Yes. The standard voices page has a sample of every voice.

Is the AI voice generator free?

You can start free with a one-time allowance of 300 characters. Pro and Team have no limits.

Can I use my own voice?

Yes. Record about 10 seconds, confirm it is your voice, and clone it. It then appears in the Studio under Cloned.

Do the voices work in other languages?

No. All voices are English.

Where is the audio made?

In your own browser, in your browser. Your text is not uploaded.

How do I choose between so many voices?

Narrow by type and accent, listen to three samples, then generate the first lines of your real script in your top two. Pick the one you can listen to for two minutes.

Can two voices speak in one script?

Yes. Write a voice name in square brackets, such as [Adam], and that voice speaks from there until you name another.

What is the difference between standard and cloned voices?

Standard voices are the 38 premade English voices everyone can use. A cloned voice is made from your own recording and is stored only in your browser.

Which voice should I use first?

Start with a voice from the type you picked, and test your own first line. Names do not tell you how a voice sounds.
