Comparison Between Custom Smartphone Acoustic Processing Algorithms and Praat in Healthy and Disordered Voices.

Objective: The aim of this study was to understand the relationship between temporal and spectral-based acoustic measures derived using Praat and custom smartphone algorithms across patients with a wide range of vocal pathologies.

Methods: Voice samples were collected from 56 adults (11 vocally healthy, 45 dysphonic, aged 18-80 years) performing three speech tasks: (a) sustained vowel, (b) maximum phonation, and (c) the second and third sentences of the Rainbow passage. Data were analyzed to extract mean fundamental frequency (f), maximum phonation time (MPT), and cepstral peak prominence (CPP) using Praat and our custom smartphone algorithms.

Impact of naturalistic smartphone positioning on acoustic measures of voicea).

Smartphone technology has been used for at-home health monitoring, but there are few available applications (apps) for tracking acoustic measures of voice for those with chronic voice problems. Current apps limit the user by restricting the range of smartphone positions to those that are unnatural and non-interactive. Therefore, we aimed to understand how more natural smartphone positions impacted the accuracy of acoustic measures in comparison to clinically acquired and derived measures.

Factors Related to Treatment Attendance for Patients Seeking Gender-Affirming Voice Therapy.

Objective: The purpose of this study was to investigate factors related to treatment attendance for patients seeking gender-affirming voice therapy (GAVT).

Method: We completed retrospective chart reviews of 50 patients (43 transgender women, three transgender men, four nonbinary patients; aged 18-67 years, = 34.92 years, = 12.
