Tone of voice is the way a person speaks and is composed of several elements, including TIMBRE, ACCENT, PITCH, RESONANCE, and EDGE. TIMBRE is the quality of a sound that distinguishes it from other sounds of the same PITCH and loudness. ACCENT is the way a person pronounces words, which can be influenced by their native language or region. PITCH is the highness or lowness of a sound, which can be affected by the speaker's vocal cords. RESONANCE is the quality of a sound that is produced when it is amplified in an enclosed space. EDGE is the sharpness or roughness of a sound, which can be affected by the speaker's emotions. Together, these elements create a person's tone of voice.
