What do you suggest if she doesn't like the sound of her voice?

Answer

Interestingly enough, many SM children say this very same thing... that they do not like the sound of their voice. A suggestion would be to try speech therapy. With SM children that truly do not like their voice, speech therapy has helped them reach a certain comfort level and to realize their voice is not so bad. Along with the speech therapy, doing typical anxiety lowering techniques such as practicing verbalization in the school with you before and after school, having frequent playdates with children from the class, bringing those kids into class before and after school etc.
