Trask (1996:381) defines voice quality as the distinctive aural coloring of an individual's voice, generated from a range of laryngeal and supralaryngeal qualities and continuing constantly throughout the individual's speech.
The human voice is composed of sound waves that travel through the air to the ear. The way in which these waves are formed and how they are transmitted to the brain are determined by the shape of the vocal tract. The vocal tract can be divided into three main sections: the oral cavity, the pharynx, and the nasal cavity. The oral cavity includes the lips, the teeth, and the tongue. The pharynx is the passage between the mouth and the esophagus, while the nasal cavity is the space inside the nose where birds' nostrils are located.
Sound waves are produced when air is pressed against the vocal cords of the larynx. These cords are made up of two layers of tissue with tiny holes between them. The outer layer forms a membrane that can vibrate back and forth like a guitar string. This is what produces the sound waves. The inner layer acts as a wall to prevent the cord from being pulled too tight or too loose, thus controlling the pitch of the voice.
The quality of the voice is mainly determined by the shape of the vocal tract.
Abstract Voice quality has been characterized as an individual's distinctive aural coloring of their voice, generated from a range of laryngeal and supralaryngeal qualities and continuing constantly throughout their speech. The term "voice" also includes the acoustic signal that results from vocal fold vibration during the production of speech.
Voice quality can be described in many ways, but it is generally agreed that good voice quality involves the use of characteristics such as warmth, clarity, strength, flexibility, and ease of modulation. A warm voice is one that is rich in harmonics and exhibits moderate-to-strong intensity fluctuations. A cold voice is one that lacks strength and smoothness in its timbre and tends to sound monotonous over time. A harsh voice is one that contains high frequencies that are not present in the speaker's natural voice and causes pain to listen to. A nasal voice is one that contains more air than liquid in its structure. This makes it dry sounding with little bass response. A hoarse voice is one that has lost most of its tone; it may even sound like it is coming from someone else's throat. A weak voice is one that has poor volume or cannot be heard over other noise levels.
There are several factors that can affect the quality of your voice including age, health, stress, language, and style.
The basic sound of the voice is referred to as quality, and it is heavily impacted by how sound flows through the vocal folds. When more air is permitted through the vocal folds, a character's voice may have a breathy quality, whereas when less air is let through, the voice may have a creaky quality. Other factors that influence voice quality include body language, tone of voice, and type of speech.
There are two types of voices: male and female. A man's voice tends to be higher in pitch than a woman's voice. This is because men use their larynx (voice box) to produce sound, while women use their trachea (windpipe). The term "male voice" can be confusing though, since not all men's voices are high-pitched and not all high-pitched voices are male. Women's voices can range from low to high, just like men's.
A person's voice can also be described as rough or smooth. The voice quality is called its "tone." People with raspy or gravelly voices often suffer from smoking or drinking too much tea or coffee. Those with soft voices are usually young children or women. The quality of a person's voice can also change depending on what they are saying. If they speak quietly, then others will hear a quiet voice. If they talk loudly, others will hear a louder voice.
Voice clarity When pitch and loudness are removed, voice quality is the component of speech that distinguishes a specific speaker's voice the most. It has both phonatory and resonant properties. Harshness, breathiness, and nasality are all characteristics of voice quality.
The term "vocal quality" applies to two different but related aspects of human voice production. The first is sound quality, which refers to the way in about our ears. The second is vocal fry, or monofrication, which is the term used to describe the type of phonation where the voice produces only one sound at a time. Vocal fry can be either open or closed. Open vocal fry involves lowering your voice without using the folds of your larynx (epiglottis and arytenoids), while closed vocal fry uses these structures to produce a lower-pitched sound.
People with harsh voices have problems with voice boxes (larynges) on one side of their throat or both. This may be because of disease or injury to these organs. People with rough voices often strain when speaking, probably because they lack the muscle control needed to avoid such straining.
Nasal voices are usually caused by colds, allergies, or injuries to the nose. A nasal voice may also result from certain medications or disorders such as sinusitis or asthma.
