E-learning courses and training videos

The MP3 files work in Articulate Storyline and Rise, Adobe Captivate, iSpring, Moodle, LearnDash, Teachable and every video editor. Because the voice is generated from text, you can update a course by changing one sentence and converting it again – no new recording session, the voice always sounds the same.

Multilingual courses: the same course in 28 languages and accents with the regular voices, or 57 languages with the AI voices.
Accessibility: audio versions of written material help learners who prefer listening or have reading difficulties.

Tips for clear narration

Write short sentences and spell out abbreviations the way they should be spoken.
Add pauses between topics with <break time="1s"/>.
Slow down key definitions with <prosody rate="slow">…</prosody> (regular voices) or use the speed slider of the AI voices.
For a friendly instructor tone, try the AI voices with an instruction such as "calm, friendly teacher".
Listen to the voices on our voice samples page and keep the same voice for the whole course.
