Voice quality refers to the characteristics and features of a person's voice that distinguish it from others, often influenced by physical, physiological, and acoustical factors. Understanding voice quality requires considering parameters like pitch, loudness, resonance, and timbre, which together affect the perceived uniqueness and aesthetic of vocal sound.

Parameters of voice quality

Pitch refers to the perceived frequency of a sound, determining how high or low it sounds to the human ear. It is a fundamental aspect of music and acoustics, influencing melody, harmony, and the tuning of musical instruments.

pitch

Loudness is a perceptual characteristic of sound that reflects its intensity as experienced by the human ear, which is influenced by both the sound pressure level and the frequency of the sound. It is subjective and can vary significantly between individuals, even if the physical attributes of the sound remain constant.

loudness

Resonance is a phenomenon in which a system oscillates with greater amplitude at specific frequencies, known as its natural frequencies, when subjected to an external force. This effect occurs when the frequency of the external force matches one of the system's natural frequencies, leading to a significant increase in energy transfer and amplitude of oscillation.

resonance

Timbre, often referred to as the 'color' or 'quality' of a sound, is what enables us to distinguish between different instruments or voices even if they are playing the same note at the same loudness. It is determined by the complex interplay of harmonics, attack, decay, and other acoustic properties that shape the overall sound wave produced by an instrument or voice.
