Introduction: In this study, the correlations between traditional acoustic measures (TAMs) and cepstral analysis (CA) were explored in Persian.
Methods: This investigation was a cross-sectional study including 179 dysphonic (n = 141) and normophonic (n = 38) speakers. The TAMs (jitter, shimmer, and noise-to-harmonic ratio) and CA (cepstral peak prominence and cepstral peak prominence smoothed) values were obtained during vowel prolongation, reading a standard sentence, and a nonstandard running speech sample using Praat software.
Objectives: The aim of the present study was to investigate the knowledge and attitudes of first-time pregnant women regarding hearing loss in infants, and to identify the key factors that influence their perceptions.
Methods: After validating and ensuring the reliability of a well-structured questionnaire consisting of 15 items, it was distributed to a total of 400 pregnant women who were experiencing their first pregnancies. Utilizing a cluster sampling method, participants were selected from both public hospitals and private gynecologist offices across diverse geographic regions in Tehran, Iran.

Objectives/hypothesis: This study aimed to validate the acoustic voice quality index version 03.01 (AVQIv3) and the acoustic breathiness index (ABI) in the Persian language.
Methods: Six judges assessed the severity degree of the abnormal overall voice quality (hoarseness) and breathiness from continuous speech (cs) and sustained vowel (sv) in 136 voices samples of dysphonic and 45 vocally healthy participants.
Purpose: Although voice therapy (VT) has been known effective in muscle tension dysphonia (MTD), it is not obviously clear which VT approach is more effective. This study aimed to compare the effectiveness of Vocal Facilitating Techniques (VFTs), Manual Circumlaryngeal Therapy (MCT), and combined VT in teachers with MTD.
Methods: This study was a double-blind parallel randomized clinical trial.
