Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Aim 1: Determine how CPP and H1-H2 change as a function of using pressed voice production in individuals without laryngeal pathology.
Aim 2: Examine the sensitivity (minimally detectable change) and responsiveness (minimal clinically important difference) of CPP and H1-H2 to detect changes in different voice production conditions.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Control Group- Without Phonotrauma
Videoendoscopy and acoustic recordings using a head-mounted microphone with a voice-specialized SLP for participants without voice disorders, acoustic recordings will involve the five repetitions of three vowels (/ɑ, i, u/) and a standard reading passage (Rainbow Passage) in three voice conditions (breathy, typical, and pressed). For all participants, high-speed videoendoscopy and simultaneous acoustic recording will occur on one repetition of a sustained /i/ in each requested condition.
Acoustic voice analysis
Acoustic recordings will involve the five repetitions of three vowels (/ɑ, i, u/) and a standard reading passage (Rainbow Passage) in different voice conditions. Control participants will produce voice in breathy, typical, and pressed conditions. Patient participants will produce voice in typical production and in a resonant voice production. High-speed videoendoscopy and simultaneous acoustic recording will occur on one repetition of a sustained /i/ in each requested condition. Data will be collected using a head-mounted microphone.
Patients Diagnosed with Phonotrauma
Videoendoscopy and acoustic recordings using a head-mounted microphone with a voice-specialized SLP for Participants who have a diagnosis of phonotrauma will be instructed to produce five repetitions of the same three vowels but in only two conditions: typical voice and "resonant" voice following stimulability assessment and with cues. They will be instructed to maintain relatively consistent volume and pitch across conditions. For all participants, high-speed videoendoscopy and simultaneous acoustic recording will occur on one repetition of a sustained /i/ in each requested condition.
High-speed videoendoscopy
High-speed videoendoscopy will occur on one repetition of a sustained /i/ in each requested condition. Exams will be recorded using the Phantom V311 high-speed camera (Vision Research, Wayne, NJ) connected to a Storz 70° rigid laryngoscope using a 400 Watt Xenon light source (Titan 400E).

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. No history of or current voice disorder
3. Auditory perceptual presentation globally within functional limits (as determined by a voice specialized SLP).
1. Diagnosed with phonotrauma (i.e., vocal fold nodules, vocal fold polyp, vocal fold pseudocyst, mid-fold edema) by a laryngologist.
2. 18-65 years of age
Exclusion Criteria
2. History of voice disorder or laryngeal surgery.
Patient Group:
1. Diagnosis of voice disorder not related to phonotrauma (e.g., vocal fold immobility, laryngeal dystonia, primary muscle tension dysphonia, etc.)
2. Previous history of laryngeal surgery or voice therapy (to avoid confounding effects of previous treatment).
