Q

When do phonatory differences begin in the age cycle?

A

Puberty
Release of androgens (testosterone) causes more pronounced growth
Vocal folds increase by 63% in males and 34% in females.

24
Q

Explain the Cover-Body model of phonation

A

The vocal folds have two layers: the cover (superficial) and the body (deep), which vibrate independently to each other. When air pressure in the lungs is released through the closed vocal folds, it vibrates the cover of the vocal folds, which creates soundwaves. The body is the stiff foundation that controls the degree of tension and mass, and adjusts the pitch and intensity of sound by changing its length and shape.

25
Q

What is a mucosal wave?

A

The top-to bottom wave-like motion that occurs on the surface of the vocal folds and allows for complex vibration that creates different vocal qualities.

26
Q

Explain the process of the Myoelastic-Aerodynamic Theory of Phonation

A

Explains how vocal fold vibration is initiated and sustained during phonation. In preparation for phonation, the airflow (aerodynamic) force displaces the vocal folds from their adducted position, and the muscular forces of the vocal folds work to resist the airflow to restore them back to their original position (elasticity). The pressure below the vocal folds must be higher than the pressure above, so that the air will flow into the glottis.

27
Q

What is the cycle to cycle variation of a period of a sound wave?

A

Jitter

28
Q

What is the rate at which vocal folds vibrate?

A

Fundamental Frequency/First Harmonic

29
Q

Formant Frequency

A

The resonant frequencies of the vocal tract, determined by the articulators positions during speech production.
Help determine the timbre of sound.
Not dependent on fundamental frequency.

30
Q

What are the measures of phonation?

A
  1. Electroglottography
  2. Endoscopy
  3. High-speed digital imaging
  4. Videokymography
31
Q

4 qualities of the vocal tract

A
  1. It is a quarter-wave resonator
  2. It’s a series of air-filled containers that are connected to each other
  3. Broadly tuned resonator
  4. Variable resonator
32
Q

What causes hypernasality?

A

When too much air escapes into the nose when speaking.

33
Q

What causes hyponasality?

A

When there’s a nasal blockage.

34
Q

What is source filter theory?

A

The “source” is the acoustic energy generated by the vocal folds from the inhalation and exhalation of air into the articulation system. The articulatory system is the “filter” that shapes the soundwaves generated by the source. Frequencies whose amplitudes are reduced by the filter are “attenuated”, and others are not attenuated.

35
Q

How are vowels distinguished on a spectrogram?

A

By the first three formants

36
Q

How does tongue position affect formants?

A

They have an inverse relationship

37
Q

Which laryngeal cartilages are paired?

A

Corniculates, cuneiforms and arytenoids

38
Q

Which laryngeal cartilages are unpaired?

A

Thyroid, epiglottis, cricoid

39
Q

Describe the process of phonation

A
  1. Breath initiation: exhalation begins the phonation process
  2. Laryngeal Raising: prepares the vocal folds by elevating
  3. Vocal Fold Adduction: vocal folds come together and close the glottis
  4. Vocal Fold Vibration: airflow causes the vocal folds to rapidly open & close
40
Q

Free vibration

A

Vibration caused by a single application of an external force (e.g. plucking a guitar string)

41
Q

Forced vibration

A

Vibration caused by the repeated application of a force to a vibrating body

42
Q

Natural Resonance Frequency (Resonant Frequency)

A

The frequency at which a body will vibrate when set into free vibration

43
Q

Muscle Tension Dysphonia

A

Excessive tension in and around the voice box that causes changes in the sound or feel of your voice.

44
Q

What is stiffness?

A

The resistance of a body to being displaced

45
Q

What is compliance?

A

The ease with which a body can be displaced

46
Q

Factors that can impact Resonance

A
  1. Cavity Shape - the shape and size of the cavities affect the frequencies that are amplified
  2. Articulatory Position - precise positioning of the articulators can affect resonance
  3. Airflow - the direction and volume of airflow through the vocal tract influences the resonance characteristic
  4. Degree of coupling between oral and nasal cavities can impact nasality of speech
47
Q

Causes: tobacco use, alcohol consumption, HPV

48
Q

Benign tumors of the vocal folds (symptoms, causes and affect on phonation)

A

Symptoms: disrupt normal vibration of the vocal folds; hoarseness, lowered pitch, increased vocal effort, loss of vocal range
Cause: overuse, misuse, strain

49
Q

A

Excessive tension around/on the vocal folds.
Symptoms: Hoarseness, breathiness, voice may get cut off suddenly, pitch too high or too low, pain or tension in throat.
Cause: upper respiratory infection, smoking, acid reflux, overuse

50
Q

Gastroesophageal reflux/laryngopharyngeal reflux (GERD/LPR) (symptoms, causes and affect on phonation)

A

Backflow of gastric contents into laryngopharyngeal area.
Symptoms: chronic throat clearing, sore throat, dysphagia, hoarseness, coughing
Cause:

51
Q

What is a spirometer used for?

A

Measuring lung capacity

52
Q

Nasal sounds have both:

A

Antiformants and nasal formants

53
Q

What is coarticulation?

A

Describes how preceding and following sounds in a word affect the target sound

54
Q

Describe the process of producing voice

A

The lungs expand and contract due to increasing and decreasing pressure, which forces the air through the trachea, which vibrates the vocal folds and creates a soundwave. The soundwave then travels through the different cavities (oral and nasal) and articulators (lips, teeth, palates, tongue) of the articulatory system, which then resonates and gives sounds its specific characteristics and meanings.

55
Q

What is manner of articulation?

A

How the articulators relate to each other and how it affects the resulting sound

56
Q

What is place of articulation?

A

Where the sound is made in the vocal tract and what articulators are used to make it.
