Once these steps have been completed, the avatar and voice can be added on demand.

Editing for text and manual cutting of sequences are possible.

Export mp4, wav or doc, url and iframe. Each element (voice, script, editing) can be downloaded separately.

Note that some words keep an English pronunciation or are spelled (e.g. “ses”, “ces” or numbers).
