COMD 5070 Final Exam Prep 2025/2026 | 120+ Solved Questions on Speech Acoustics, Digital Signals, Vocal Tract Physiology, Spectrograms & Motor Control

This COMD 5070 Final Exam study guide offers 120+ fully answered multiple-choice questions, carefully designed to reflect the 2025/2026 course objectives for students in Speech Science, Communication Disorders, and Audiology. Covering both technical foundations and applied acoustic analysis, the guide prepares learners for final assessments with high-yield content on speech acoustics, signal processing, speech production, and motor control. Key topics include: Acoustic physics: pressure, intensity, amplitude, frequency, inverse square law Digital vs analog signal theory: quantization, sampling, aliasing, A-to-D and D-to-A conversion Spectrograms and spectra: reading time-frequency data, wide-band vs narrow-band resolution Vocal physiology: vocal fold vibration, jitter, shimmer, phonation efficiency, VRP (voice range profile) Speech sound analysis: vowels, diphthongs, fricatives, affricates, voiced vs voiceless stops Filters and resonance: low-pass, band-pass, formants, filter theory, vocal tract tuning Motor control in speech: coordinative structures, EMMA, electropalatography, perturbation studies Coarticulation and timing: VOT (voice onset time), F1 transitions, articulatory overlap Speech perception: clear speech cues, phonation markers, prosody, s/z ratio Neural and biomechanical models: frame theory, spatiotemporal index, feedback mechanisms This document is ideal for: Students enrolled in COMD 5070 at the University of Utah or equivalent graduate-level courses in speech acoustics and instrumentation Speech-Language Pathology and Audiology students preparing for final exams, oral comps, or Praxis Learners and tutors seeking a comprehensive review tool with high exam fidelity and concise explanations Educators designing mock exams or classroom review sessions focused on acoustic theory and clinical relevance With a balance of conceptual clarity and applied science, this final exam prep resource ensures students are fully equipped to succeed in COMD 5070 assessments and related clinical foundations.
