Public speaking can be difficult for most of us. Speaking in front of strangers requires good verbal and nonverbal communication. I attended a lecture were the speaker spoke very quickly and mumbled, constantly looked down, and had a thick accent. Needless to say, he was difficult to understand which was too bad because he had interesting things to say. When speaking in public volume, tone, breath support and non-verbal language can distract from the verbal message being imparted.
