Voice can lend credibility to a speaker and weight to a statement. We do not have only one voice, but we can learn to use different vocal qualities to our advantage.
Does your accent or the way you speak sometimes seem to get in the way? A clear message needs clear pronunciation. Dialects are part of who we are.

Delivering speeches with the same degree of professionalism as in your first language is quite another. Therefore, a good preparation for any public event is crucial. It must cater for both linguistic and rhetorical needs.
