Oral Anatomy
I am the only movable bone of the skull
What is the mandible?
This speech subsystem includes the tongue, lips, jaw, and oral cavity.
What is the articulatory subsystem?
During oral sounds such as /p/ and /t/, I elevate to close the velopharyngeal port.
What is the velum?
The true vocal folds are primarily responsible for this.
What is voice production?
I am the primary muscle of inspiration during quiet breathing.
What is the diaphragm?
I am known as the only "floating bone" in the body.
What is the hyoid?
This tongue muscle is primarily responsible for protruding the tongue.
What is the genioglossus?
I am the primary muscle for velopharyngeal closure.
What is the levator veli palatini?
The false vocal folds primarily serve this function.
What is airway protection?
This variable most directly influences vocal pitch.
What is vocal fold vibration rate?
I am the primary elevator of the jaw.
What is the masseter?
This intrinsic tongue muscle narrows and elongates the tongue.
What is the transverse muscle?
Compared with low vowels, high vowels are produced with this type of tongue position.
What is a higher tongue position?
This vocal fold movement is required for breathing.
What is abduction?
F₀ is another name for this acoustic measurement.
What is fundamental frequency?
These muscles primarily constrict the pharynx.
What are the superior, middle, and inferior pharyngeal constrictors?
Unlike most articulators, I can change both my position AND my shape during speech.
What is the tongue?
These three vowel sounds—/aɪ/, /ɔɪ/, and /aʊ/—belong to this class of vowels.
What are diphthongs?
I am the only intrinsic laryngeal muscle that abducts the vocal folds.
What is the posterior cricoarytenoid?
Fundamental frequency is the rate at which the vocal folds vibrate and is measured in this unit.
What is Hertz (Hz)?
This muscle group elevates, shortens, and widens the pharynx rather than constricting it.
What are the longitudinal pharyngeal muscles?
This term describes overlapping articulatory movements between speech sounds.
What is coarticulation?
Of see, boot, bed, and boy, this word contains a diphthong.
What is boy?
I raise vocal pitch by lengthening the vocal folds.
What is the cricothyroid?
Weakness of these muscles would make it difficult to maintain adequate breath support for longer utterances.
What are the expiratory muscles?
