Herbal Medicine and Voice Quality: Uncovering the Impact Through Acoustic Analysis.

Objective: Rutarin, an herbal formulation combining powdered seeds of Cydonia oblonga (quince) and aerial parts of Origanum majorana (marjoram), is used to address respiratory issues and enhance voice quality. This study investigates the effects of Rutarin on voice parameters, including fundamental frequency (F0), jitter, shimmer, harmonics-to-noise ratio (HNR), cepstral peak prominence (CPP), and smoothed cepstral peak prominence (CPPS).

Methods: Voice samples of 79 individuals who produced a sustained vowel /a/ were examined before and after consuming either Rutarin or warm water.

Cepstral Analysis of Voice in Patients With Temporomandibular Disorders.

Objectives: This study aimed to assess the voice quality of patients with temporomandibular disorders (TMDs) compared with healthy subjects using cepstral analysis and investigate the relationship between the TMD severity and the values of cepstral analysis.

Methods: Subjects who met the inclusion criteria completed a general health questionnaire and the Fonseca Anamnestic Index. Patients who had TMDs with FAI were subjected to an examination based on the Diagnostic Criteria for Temporomandibular Disorders.

The feasibility of using acoustic measures for predicting the Total Opacity Scores of chest computed tomography scans in patients with COVID-19.

To study the possibility of using acoustic parameters, i.e., Acoustic Voice Quality Index (AVQI) and Maximum Phonation Time (MPT) for predicting the degree of lung involvement in COVID-19 patients.

WordPars: A tool for orthographic and phonological neighborhood and other psycholinguistic statistics in Persian.

This paper presents a Windows program providing statistics on word and non-word stimuli in Persian, including word frequency, orthographic and phonological length, orthographic and phonological neighbors, and transposed-letter neighbors. It also generates possible non-words that are orthographic neighbors of the target word. Persian is an under-represented Indo-European language that has historically been influenced by Arabic and adopted certain characteristics in its writing, e.

Do you have COVID-19? An artificial intelligence-based screening tool for COVID-19 using acoustic parameters.

This study aimed to develop an artificial intelligence (AI)-based tool for screening COVID-19 patients based on the acoustic parameters of their voices. Twenty-five acoustic parameters were extracted from voice samples of 203 COVID-19 patients and 171 healthy individuals who produced a sustained vowel, i.e.

Voice Quality Evaluation in Patients With COVID-19: An Acoustic Analysis.

Objectives: With the COVID-19 outbreak around the globe and its potential effect on infected patients' voice, this study set out to evaluate and compare the acoustic parameters of voice between healthy and infected people in an objective manner.

Methods: Voice samples of 64 COVID-19 patients and 70 healthy Persian speakers who produced a sustained vowel /a/ were evaluated. Between-group comparisons of the data were performed using the two-way ANOVA and Wilcoxon's rank-sum test.

A Case Study of Negative Affixes in Sadegh Hedayat's Letters: The Effect of Bipolar Mood Disorder.

This research studies the morphological features found in Sadegh Hedayat's letters, who, based on linguistic and psychological studies, may have had bipolar disorder. It aims to assess the impact of various types of moods on the frequency of negative affixes through qualitative analysis of the letters' text. The letters are written in Persian, and include six negative derivational affixes.
