COMD 5070 – 100+ Solved Questions 2025/2026 – Subglottal Pressure, Voice Registers, Source-Filter Theory, Formants, VOT, Stops & Fricatives

This comprehensive exam resource for COMD 5070 presents 100+ fully solved questions and answers from the 2025/2026 exam, targeting critical concepts in speech science, voice production, and acoustic phonetics. It is organized to enhance clinical understanding and theoretical precision in topics related to phonation, articulation, resonance, speech aerodynamics, and spectrographic analysis. Highlights include: Speech aerodynamics: average airflow, volume velocity, subglottal pressure (Psub), intraoral pressure, and phonation threshold pressure (PTP) Respiratory coordination: rib cage/abdominal movements during speech and singing, spirometry, vital capacity, and esophageal pressure methods Voice physiology: vocal fold oscillation, vocal registers (modal, pulse, loft), laryngeal resistance, vocal fatigue, and dehydration effects Acoustic phonetics: VOT (voice onset time), harmonic spectral slope, formant frequency patterns (F1, F2), vowel quadrilaterals, and formant transitions Articulatory phonetics: stops, fricatives, affricates, nasals, liquids, glides, diphthongs, place and manner cues Instrumental analysis: pneumotachograph, pressure transducers, manometers, spectrograms, and waveform interpretation Theoretical models: Ohm’s Law in phonation, Source-Filter Theory, vocal tract transfer function, periodicity vs. aperiodicity Ideal for mastering both exam-based recall and applied clinical knowledge, this guide bridges foundational theory and real-world assessment tools used in speech-language pathology. Recommended for students in: Graduate Communication Sciences and Disorders (CSD) programs Speech-Language Pathology and Audiology training Advanced phonetics, articulation, and acoustic measurement courses SLP licensure, board exam, and comprehensive oral exam preparation Each answer includes exam-grade definitions and concise examples. This resource is highly effective for memorization, review sessions, and oral defense support.
