Project 4: Ambulatory Biofeedback and Voice Therapy for Patients With Vocal Hyperfunction

AVM-B is software on the Voice Health Monitor that uses a neck-placed accelerometer to sense neck skin vibrations during voicing in daily life. The AVM-B consists of cues every time the patient exceeds a subject-specific threshold, \[100% frequency AVM-B\] and/or summary statistics every 2 minutes of voicing \[Summary AVM-B\].

CTT is a 4-week (1 45-minute session per week) evidence-based voice therapy for patients with VH, developed primarily to maximize the amount and speed of generalization outside the therapy session. It consists of 3 required targets: Decreased overall auditory-perceptual voice severity, improved discrimination between baseline and improved voicing, and adherence to CTT recommendations in daily life. The three optional targets are decreased overall auditory-perceptual severity across an increased pitch range, loudness range, and decreased rate of speech. All voice-related targets are modified through practicing voicing with increased forward resonance and mean airflow in spontaneous speech/conversation.
