Great resource for Training & Communication initiatives

We're using Synthesia to create explainer videos. It's just easier, faster, and more cost-effective to use Synthesia than to record an actual person doing the explanation.

Frequently Asked Questions

Frequently Asked Questions

How do I add voice to videos in Synthesia?

You don't need to create an audio recording, edit the recording and upload the audio file, the way you would with a standard voiceover video maker.

All you need to do is type or paste text into the video editor and our software will convert that text into speech. That's it!

Can I adjust pronunciation?

Yes! There is an easy way (or two) to adjust your text-to-speech voiceover and improve sound pronunciation.

The first is simple - insert hyphens and phonetic spelling to improve pronunciation in the audio file. That includes spelling numbers as words and spelling acronyms as they sound.

Another way is to use punctuation marks to add emphasis and pauses to the audio file.

Lastly, use SSML (Speech Synthesis Markup Language) to add timed breaks to the audio.

In how many languages can I create videos?

You can make a voice over video in more than 60+ languages and accents using our text-to-speech engine.

You can switch between languages in different video segments (slides), but not in the same slide.
