Summary
Speaking voice professionals experience more voice complaints and acoustic changes than nonspeaking professionals, indicating voice professionals are not a uniform group. This study highlights the distinct impacts of daily voice use on different professional subgroups.
Area of Science:
- Otolaryngology
- Speech-Language Pathology
- Acoustic Analysis
Background:
- Voice professionals are broadly categorized into speaking and nonspeaking subgroups (e.g., singers).
- Both groups face high vocal demands, but the comparative effects of daily voice use on their vocal health remain unexamined.
- Previous research has not directly compared these distinct professional subgroups.
Purpose of the Study:
- To compare the speaking voice characteristics of speaking and nonspeaking voice professionals.
- To assess vocal health in individuals without current vocal fold pathology or voice complaints.
- To investigate potential differences in voice changes due to daily vocal demands.
Main Methods:
- A cohort of 50 speaking and 50 nonspeaking voice professionals was recruited.
- Participants underwent voice-related history assessment.
- Comprehensive voice analysis and videostroboscopy were performed for each participant.
Main Results:
- Speaking voice professionals reported a significantly higher incidence of voice-related complaints compared to nonspeaking professionals.
- Acoustic analysis revealed significantly higher fundamental frequency, jitter percent, and harmonic-to-noise ratio in speaking voice professionals.
- Videostroboscopy showed no significant differences in vocal fold appearance between the two groups.
Conclusions:
- This study is the first to analyze the effects of daily voice use on distinct subgroups of voice professionals without current vocal pathology.
- Voice professionals should not be treated as a monolithic group due to differing vocal impacts.
- Excessive voice use appears to have more detrimental effects on speaking voice professionals than on nonspeaking voice professionals.

Non-verbal communication extends beyond gestures and facial expressions to include vocal elements known as paralanguage. Paralanguage consists of non-verbal vocal cues such as pitch, loudness, speech rate, pauses, and non-verbal vocalizations like laughter, sighs, and moans. These elements not only accompany speech but also provide critical emotional and contextual information.The Role of Paralanguage in CommunicationParalanguage adds depth to spoken language by conveying emotions and...

The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Auscultation is a crucial component of the physical assessment of the respiratory tract. It offers valuable insights into airflow through the bronchial tree and potential lung obstructions. This process involves careful listening to breath, voice, and adventitious sounds, which can reveal a wealth of information about a patient's respiratory health.
Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.

Language, whether spoken, signed, or written, consists of specific components: lexicon and grammar. The lexicon is the vocabulary of a language, comprising its words. Grammar is the set of rules used to convey meaning through the lexicon. For example, English grammar adds “-ed” to most verbs to indicate past tense. Words are formed by combining phonemes, which are the basic sound units of a language. Different languages have different sets of phonemes (e.g., “ah” vs.
