Here’s a list of 100 top questions with answers on voice science, covering topics related to vocal anatomy, phonation, resonance, acoustics, and voice training.

1. Anatomy & Physiology of the Voice

What is voice science?

• Voice science studies the anatomy, physiology, acoustics, and function of the human voice in speech and singing.

Which organs are involved in voice production?

• The lungs, diaphragm, larynx (vocal cords), pharynx, oral and nasal cavities, and articulators (tongue, lips, teeth).

What are vocal folds?

• The vocal folds (cords) are two bands of muscle tissue in the larynx that vibrate to produce sound.

How do the vocal folds produce sound?

• They vibrate when air from the lungs passes through them, generating sound waves.

What is the larynx?

• The larynx (voice box) houses the vocal folds and is responsible for sound production.

What is phonation?

• Phonation is the process of sound production by the vibration of the vocal folds.

What is the role of the diaphragm in voice production?

• The diaphragm helps regulate airflow and breath support, which affects voice control.

What is the difference between the true and false vocal folds?

• True vocal folds vibrate for speech, while false vocal folds (vestibular folds) help with protection but do not produce voice.

What muscles control vocal pitch?

• The cricothyroid muscle (stretches for higher pitch) and thyroarytenoid muscle (shortens for lower pitch).

What is the glottis?

• The space between the vocal folds that opens and closes during speech.

2. Voice Acoustics & Resonance

What is vocal resonance?

• The amplification and enrichment of sound by the throat, mouth, and nasal passages.

Why does my voice sound different when recorded?

• Recordings capture sound transmitted through air, while we hear our voice through both air and bone conduction.

• A relaxation method to reduce vocal tension and enhance resonance.

How can I eliminate a monotone voice?

• Varying pitch, inflection, and emphasis in speech helps create vocal dynamism.

What foods are best for vocal health?

• Hydrating foods like fruits, non-caffeinated teas, and honey.

How does emotion affect the voice?

• Emotion alters pitch, tone, and resonance, conveying different feelings.

How can I project my voice better?

• Using proper breath support, open throat resonance, and forward placement.

6. Voice Perception & Psychological Aspects
