With the support of good posture and breathing, vocal clarity and flexibility can be achieved through the effective use of:

• articulation: the precision used in the formation of sounds and speech.
• clarity: the accurate formation of sounds with the voice.
• emphasis: the use of particular stresses in the spoken delivery of a sentence to highlight important words or phrases to improve comprehension for a live audience.
• inflection: the variation of the pitch and tone within a sentence to clarify emotional quality and intended meaning within a sentence for a live audience.
• pace: the speed with which a sentence or passage is delivered.
• pause: a planned break in the delivery of a phrase, sentence or passage.
• pitch: refers to the intensity of the vibrations in the voice making it seem higher or lower.
• projection (loudness): the strength or power used when speaking.
• tone: the emotional qualities added to a vocal performance by adjusting the types of sounds produced by the voice. These in particular can help convey a sense of a character’s subtext.
