[Creating materials for in-house training] This is voice synthesis software for e-learning materials that can be used for free!

There are more opportunities to create slides and seminar videos using PowerPoint for in-house training.
Among them, the number of scenes where "I want to add narration to slides and videos" is increasing. Recently, I often add narration to my presentations.


  • It's embarrassing to do it with your own voice
  • I was refused by other people
  • Not enough to hire a voice actor
  • I can't hire a voice actor on a budget

There is no end to my worries about adding narration.

Therefore, we recommend text-to-speech services and voice synthesis software.

Sentence reading software is software that converts documents such as text and characters into voice and reads them aloud.
