Voice Exam 2

What are the three emotional perspectives patients may have regarding their voice evaluation?

Anxiety, Anger, Ambivalence

What is the primary purpose of a diagnostic evaluation of voice?

To determine if the voice is normal and identify the etiology of any pathology.

What are the key components of the diagnostic evaluation process?

General/Medical History, Voice History, Auditory-Perceptual Evaluation, Physical Examination, Laryngo-videostroboscopic Examination, Phonatory Function/Acoustic Analysis, Aerodynamic Analysis, Other measures.

What is hoarseness in the context of voice disorders?

A change in the voice that varies in severity.

What does vocal fatigue refer to?

The effort required to speak becomes excessive.

What does breathiness in voice disorders indicate?

A quiet, light voice where air escapes between the vocal folds.

What is meant by reduced phonational range?

Inability to reach notes while singing, often resulting in a monotone voice.

What is aphonia?

The complete loss of voice, which is very rare and usually indicates extreme hoarseness.

What are some typical symptoms of voice problems?

Hoarseness, Vocal Fatigue, Breathiness, Reduced Phonational Range, Aphonia, Uncontrolled Pitch, Strain/Struggle, Tremor, Pain.

What aspects should be included in a patient's general/medical history during voice evaluation?

Length and description of symptoms, swallowing/weight history, cough/hemoptysis, medications, illnesses, and surgeries.

What factors should be assessed in a patient's voice history?

Onset, variation during the day/weekend, emotional triggers, vocal environment, and vocal use.

What are some questions to ask when evaluating a child aged 3-5 for voice disorders?

Questions about school, crying/tantrums, and play.

What is the responsibility of the interviewer during the voice evaluation process?

To complete a comprehensive case history while assessing the client's voice.

What is the Voice Handicap Index?

A measure used to assess the impact of voice disorders on an individual's life, available for both adults and pediatrics.

What does perceptual evaluation in voice assessment focus on?

Vocal quality and vocal characteristics.

What are the two types of reliability in perceptual ratings?

Intra-judge reliability (consistency within oneself) and Inter-judge reliability (consistency among different professionals).

What are categorical rating scales used for in voice evaluation?

To classify voice quality into categories such as mild, moderate, and severe.

What is the purpose of paired comparison in voice evaluation?

To compare two samples and determine which one has more of a specific quality, such as breathiness.

What is the Equal Appearing Interval (EAI)?

A perceptual rating sheet used for voice evaluation, often on a scale of 0-7 or 0-10.

What does CAPE-V stand for?

Consensus Auditory Perceptual Evaluation of Voice.

What equipment is essential for voice recording?

Microphone and recording device (e.g., digital recorders or apps).

What types of tasks are used in voice recording protocols?

Non-speech versus speech tasks, including vocal aerobics and functional tasks.

What is Maximum Phonation Time (MPT)?

A non-instrumental measure assessing how long a person can sustain a vowel sound.

What does the S/Z ratio measure?

It assesses respiration ability by comparing the duration of the 'S' sound to the 'Z' sound.

What is the average MPT for young adult females and males?

15-25 seconds.

What is the purpose of Fundamental Frequency in voice analysis?

To measure the pitch of the voice, defined by the number of cycles per second (Hertz).

What is the average fundamental frequency for males?

100-125 Hz.

What is the average fundamental frequency for females?

200-225 Hz.

What does 'Optimal Pitch' refer to?

The best quality and maximum intensity of voice with minimal effort, biologically determined for an individual.

What is the purpose of perturbation measures in voice analysis?

To assess the stability of voice through jitter (frequency variation) and shimmer (amplitude variation).

What is the significance of stroboscopy in voice assessment?

It uses pulsing light to simulate vocal fold movement, allowing for detailed observation of vocal fold function.

What are laryngoscopic observations used to assess?

Vocal fold movement, approximation, tissue changes, and laryngeal dimensions.

What does high-speed laryngeal imaging allow for?

Recording at rates of 2-4 kHz to visualize even very irregular vocal fold cycles.

What is aerodynamic measurement in voice assessment?

It involves measuring intraoral air pressure, airflow, and laryngeal resistance during phonation.

What is the role of electromyography in voice analysis?

To assess muscle activity related to voice production, including innervation and recruitment patterns.

What is the purpose of the Speed Quotient in vocal fold kinematics?

To measure the ratio of the opening phase to the closing phase of vocal fold movement.

What does the Open Quotient measure?

The ratio of open time to total time during vocal fold vibration.
