Vocal clarity
Vocal clarity is how clearly and understandably you speak — a blend of articulation, steady pace, and few disfluencies. Clear speech is perceived as more confident and competent, regardless of content.
Pace matters: roughly 120–160 words per minute is a comfortable band for most listeners; much faster reads as nervous, much slower as hesitant.
SURGO scores clarity from your transcription and disfluency rate so you get a concrete number to improve.
