vocing 1

Where is voicing produced

In the larynx

What are the two main cartilages in the larynx

Thyroid and cricoid cartilage

Where is thyroid cartilage

On top of cricoid cartilage

What are the two cartilages connected by

A joint

What is inside two cartilages

Vocal folds or cords which is two thick flaps of ligament and muscle to produce speech

Where do vocal folds come together

At the front of the larynx and attach to inside of thyroid cartilage

Vocal cords are also attached to what

A small pyramid shaped cartilage called aryetenoid cartilages

What are arytenoid cartilages

they move vocal folds into a variety of positions to produce speech

What are opening and closing vocal folds called

Abduction and adduction

What is abduction

Going appart

What is adducuction

Going together

What is phonation

The generation of sound in the larynx by vibration of vocal folds

many what are produced with vibrating vibrating vocal folds

Constants

What does it mean when vocal folds are in an adducted position

Phonation can take place

What is aerodynamic myoelastic

It explains the vocal fold vibration

What does aerodynamic mean

It’s the movement of air

What’s myoelastic

Muscles are springy

When does vibration happen

When there is a rapid repeated opening and closing of glottis

The stages of what happens when they move apart

1. Vocal forms are adducted due to movement of arytenoid cartilages which closes glottis and blocks off flow of air from lungs

2. Vocal cords move apart

3. More pressure so vocal cords are even further apart

4. Vocal cords are pushed apart and compressed where air bursts through glottis and eventually come out of vocal tract

What happens when vocal folds move back to enter

It’s due to myoelastic tension

Due to the Bernoulli effect when air travels through narrow passage meaning pressure and speed increases and pressure across passage and decreases so passage gets sucked back other

Sounds produced with vibrating vocal cords

All nasals

All approximates

All vowels

All voiced fricatives

Which sounds are without vibration

Glottal stop

Voiceless glottal fricatives

Other voiceless fricatives
