Voice Test 1.3.2

This software provides a unique opportunity for users to evaluate their vocal health by testing various voice parameters, specifically frequency, jitter, and shimmer. The measured values are compared against established thresholds, and the application issues warnings at two different levels based on these comparisons.

The human voice is a multifaceted phenomenon, produced through a complex interplay of several organs, including the lungs and vocal folds, as well as articulators such as the tongue, palate, cheeks, and lips. Sound is generated by the rhythmic vibration of the vocal folds, which can be vulnerable to a range of health risks.

Phoniatrics experts can often assess the condition of an individual's vocal tract by simply listening to their voice. In some cases, they utilize advanced equipment to measure voice parameters more precisely, evaluate the health of the vocal folds and glottis, and determine if medical intervention is necessary. Notably, smokers and individuals who rely heavily on their voices for professional purposes are classified as being at higher risk for vocal fold disorders.

In this application, fundamental frequency, jitter, and shimmer values are calculated and compared with predefined thresholds. The results are presented in both graphical and numerical formats. It is important to note that this tool is tailored for adult male and female voices and is not designed for children.

The primary aim of this program is to enhance users' awareness regarding the health of their vocal folds. However, it should be emphasized that the test results provided by the application are only indicative and cannot replace professional medical examinations.

Users are encouraged to produce the long letter 'a' naturally, ideally as part of a word such as "five." To ensure accurate recording, it is advisable to maintain the power indicator within the goal zone for a duration of three seconds.

If the results do not fall within the green zone, users should repeat the recording process multiple times. Persistent warnings may indicate that voice parameters deviate from standard values, thereby necessitating a consultation with a healthcare professional.
