Summary
The Spectrographic Vocal Assessment Protocol demonstrates strong reliability and validity for analyzing vocal fold disturbances. This tool offers dependable insights for speech-language pathology assessments.
Area of Science:
- Speech-language pathology
- Acoustic analysis
- Voice disorders
Background:
- Vocal fold disturbances impact voice quality and communication.
- Objective assessment tools are crucial for accurate diagnosis.
- The Spectrographic Vocal Assessment Protocol aims to provide such a tool.
Purpose of the Study:
- To evaluate the reliability and validity of the Spectrographic Vocal Assessment Protocol.
- To determine the protocol's effectiveness in distinguishing between normal and disordered voices.
Main Methods:
- 50 female participants (25-62 years) were analyzed, including those with normal larynx/posterior glottal gap and vocal fold disturbances.
- The vowel /a:/ was recorded and analyzed using Real Time Spectrogram software.
- Two speech therapists assessed spectrographs using the protocol; reliability (inter- and intrajudge) and criterion validity were statistically analyzed.
Main Results:
- Protocol reliability showed moderate to almost perfect agreement for both broadband and narrowband items (interjudge: 0.462-0.922; intrajudge: 0.865-1.000).
- Most items demonstrated statistically significant agreement, indicating good reliability.
- Criterion validity was supported, as the protocol significantly differentiated between participants with normal and altered vocal fold diagnoses for most items.
Conclusions:
- The Spectrographic Vocal Assessment Protocol exhibits adequate reliability and validity.
- This protocol is a promising tool for the objective assessment of voice disorders.

13.6K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:

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.
