Changing the pitch while speaking can convey shades of meaning such as emphasis or surprise, or distinguish a statement from a question.

Articulation focuses on making individual sounds and pronunciation focuses on stress, rhythm, and intonation of the syllables in the word.

Speakers may use many different English dialects to change the pitch, rate, volume, and use of pauses to achieve vocal variety.
