Text to speech

Text to speech MP3. Make it, keep it, download it.

With Clonylab you can turn text into an MP3 in a few clicks. Pick a voice, paste your script and press Generate speech. The MP3 is made in your browser and saved in your History, where you can play it and download it as MP3 or WAV. You can start free with no card.

Free to start, no card needed. English only. An account is required.

From text to MP3 in three steps

  1. Write or paste the script

    Open the Studio and paste your text. Add pause and style tags if you want to direct the reading.

    A script in the Studio with a pause tag, a slow tag and a voice tag, and the Pause, Slow, Fast, Soft and Loud buttons
    Tags go right inside your script. The buttons insert them for you.
  2. Choose a voice and generate

    Pick one of the 38 voices or one of your clones, then press Generate speech. A task starts, and you can keep working.

    Filter the voices, press play to hear one, and pick it.
  3. Play it and download

    The finished voice-over appears in your History. Press play to listen. Use the download button to get the MP3.

Each voice-over is its own task, so you can start the next one while the first is still finishing. That is handy when you have a list of scripts to turn into files.

Your MP3 files live in your History

You do not have to download a voice-over straight away. Everything you generate is kept in your History, in your browser, until you delete it. That is where you play, find and download your files.

MP3 or WAV: which should you download?

Clonylab makes an MP3 first. When you choose WAV, the app converts that MP3 into a WAV file. So both files carry the same sound. The difference is the container.

Getting an MP3 that sounds good

  • Choose the voice first. Press play on a sample, then pick it.
  • Write for the ear. Short sentences read better aloud than long ones.
  • Add pauses. Put [pause 1s] where a speaker would breathe.
  • Slow the important words. Wrap them in [slow] and [/slow].
  • Listen before you share. Play the whole voice-over once at normal speed.

There is a full list of tags on the AI voiceover generator page.

Sharing your MP3

On the free plan, credit “Made with Clonylab” when you share a voice-over. Pro and Team do not have that line. The standard voices are licensed for commercial use. Read text to speech for commercial use for the details, and the Voice licences page for each licence.

Ten scripts in one afternoon

MP3s usually come in batches. A set of video intros, a series of lessons, a list of product lines. Here is a workflow that suits Clonylab’s task queue.

A batch workflow for making many MP3 files
StepWhat to doWhy
1Write all ten scripts in a text file firstYou can edit in a real editor
2Choose one voice and one set of slidersThe set sounds like one series
3Paste the first script, press Generate speechThe first one downloads the voice files
4Paste the next and press Generate again straight awayEach is its own task, so they run one after another
5Listen to each in the HistoryFix problems by editing the script and generating again
6Press Download AllYou get the whole batch

Batches need Pro or Team in practice, because the free plan has only 300 characters in total. See unlimited text to speech for what that covers.

Keeping your MP3 files organised

Once you make more than a handful of files, names and folders matter. The downloaded file name comes from your voice-over, so a little discipline before you generate saves time later.

A simple way to organise MP3 voice-overs
WhatA good habit
ScriptsNumber them in your text file: 01 intro, 02 steps, 03 outro
VoicesUse one voice per series, and note which one
DownloadsPut each batch in a dated folder
BackupsCopy finished files somewhere safe, because History lives in your browser
VersionsChange the script, generate again and keep the old file until you are sure

What decides how your MP3 sounds

Three things shape the sound, in this order.

  • The voice. Different voices have different tone and pace, so choose first.
  • The script. Short, clear sentences with natural pauses make the biggest difference.
  • The settings. The sliders and tags fine-tune speed, pitch, pauses and volume.

Then listen once before you download. If a name is read oddly, respell it the way it sounds and generate again. You can read more about directing a reading on the AI voiceover generator page.

A quality checklist before you publish

  • Listen all the way through. Play the whole voice-over once, at normal volume.
  • Check names and numbers. Respell anything that sounds wrong and generate again.
  • Check the ends. The first and last words should not be cut or rushed.
  • Match the volume. Use the Volume slider so the audio sits well with your music or video.
  • Keep a copy. Download the file, and keep your script next to it.

These five checks take about a minute and catch almost every problem.
