This COMD 5070: Voice Measures study guide provides over 100 expertly answered questions that reflect the latest 2025/2026 curriculum in speech science and voice physiology. Focusing on the assessment, measurement, and interpretation of voice disorders, this guide equips students with essential knowledge for analyzing vocal fold behavior, laryngeal imaging, perturbation, and clinical evaluation techniques. Key topics covered in this exam-prep document include: Normal vs disordered voice physiology: understanding vocal fold activity and treatment rationale Laryngeal imaging techniques: laryngeal mirror exam, rigid and flexible endoscopy Stroboscopy: flash synchronization, vocal fold oscillation simulation, limitations in severe dysphonia High-speed imaging: filming rates, pros and cons, visualizing true slow-motion phonation Electroglottography (EGG): principles, waveform interpretation, contact area changes, voice quality monitoring Vocal perturbation: jitter (pitch variation), shimmer (amplitude variation), and their perceptual correlates (hoarseness, roughness) Voice acoustic measurements: fundamental frequency (F0), signal clarity, and spectral analysis Clinical application of voice measures: diagnosis, tracking progress, treatment outcomes Neurological and biomechanical causes of irregular phonation Limitations of acoustic fingerprints: importance of human perception in diagnosis This document is ideal for: COMD 5070 students at the University of Utah or similar speech science courses Graduate students in Speech-Language Pathology, Voice Science, and Communication Disorders Learners preparing for finals, practical exams, or clinical application modules Tutors and faculty designing review sessions or assessment tools in voice and instrumentation Structured in Q&A format for efficient learning and rapid recall, this guide blends theory and clinical utility—essential for both exam success and voice assessment competence. Keywords: COMD 5070 voice measures, laryngeal mirror exam, vocal fold vibration, stroboscopy limitations, jitter and shimmer, electroglottograph EGG, vocal perturbation, hoarse voice analysis, vocal fold imaging, phonation physiology, fundamental frequency F0, flexible scope, rigid scope, voice disorders assessment, speech acoustics

Solved



You cannot ..............unless you know how the normal system works - 🧠

ANSWER ✔✔understand a disorder


Voice problems come from......Therapy aims to..................Detailed

information about the activity of the larynx helped assessment and

treatment - 🧠 ANSWER ✔✔disordered vocal fold activity


improve vocal fold movements

Why must we know the physiology of a voice disorder to treat it? - 🧠

ANSWER ✔✔there can be several different causes of a voice disorder.

These disorders may share several perceptual features. (Hoarseness or

roughness). They may arise for a variety of reasons.

,One motivation for us to get more physiologic detail of what's going on at

the level of the larynx is that we can understand the etiology or the cause of

the voice disorder in greater detail. Then we can tailor make our therapy to

address the disordered physiology.

What is a laryngeal mirror exam? Who typically does this exam? What can

you typically see? - 🧠 ANSWER ✔✔mirror is placed toward the back of the

mouth. The clinician holds the tongue of the patient.

She shines a light at the mirror, which is reflected down to the larynx.

The image is reflected back up so that person can see the structures of the

larynx in a low level of detail.




Physician that doesn't specialize in voice




gross abnormalities in structures

Why do they pull on the tongue in a laryngeal mirror exam? - 🧠 ANSWER

✔✔This helps tug on the epiglottis, the cartilage at the front of the larynx. It

, helps to pull it out of the way so when you hold the mirror in place, you

have a less obstructed view of the vocal folds.

What kind of sounds can the pt do in a laryngeal mirror exam? - 🧠

ANSWER ✔✔sustained phonation /i/


What is a rigid scope exam? who typically performs these? - 🧠 ANSWER

✔✔a rigid endoscope, a metal rod that contains fiber optic cables, which

carry light from a bright light source. This light shines from the end of the

scope, downward toward the larynx. There's also a lens on the tip of the

scope that brings an image back up and through fiber optic cables to a

camera which can then display it on a screen.




only see vocal folds, no other structures




only phonate vowel
