Text to Voice - Choose Voice based on variable

Hi,

My course has learners choose a character. These characters are out of the box from storyline. When they choose, a variable gets set to their name. Example: Mihaela. Throughout the course, based on which character they choose at the beginning that character will show up. Is there a way for storyline to play text to speech, same for all the characters to play depending on which character they chose at the beginning of the course?

Thanks
