Both trained and untrained listeners would consider the voice extremely abnormal. The voice characteristic is highly distracting. The ability to effectively communicate is consistently affected. The dysphonia causes phonation to be mainly absent or extremely effortful.
- They present minimum discomfort to the patient.
- They are noninvasive techniques.
- In most cases, they require minimal amounts of time to complete the procedure.
- They provide relatively immediate test results.
- They require minimum expense
- Background Info
- Evaluation of muscle tone tension
1. Evolution of the SLP’s environment(s).
2. Reimbursement issues.
3. Information re: the coordination of speech subsystems.
4. Instrumental measures may help form a more solid foundation for clinical judgments.
5. Instrumental measures allow for the comparison of vocal performance to appropriate normative data.
ALSO, objective measures often aid the clinician in identifying mild disorders and may direct the clinician towards a reexamination of perceptual judgments

May be associated with voice disorders as:
- An underlying cause
- A result of coping with an incapacitating voice disorder
Often made on a subjective basis. Client may report the sensation of tension, even pain, during speaking. It also may be the judgement of a clinician based upon auditory and visual observations.
standard deviation & pitch sigma
- May be computed for the 2nd sentence of the Rainbow Passage, but more error may be expected (approx. 10% errors possible in relation to the entire passage)
Elicited via open-ended questioning techniques or picture description tasks
- Collect a continuous speech sample of at least 14 seconds in duration (this duration provides an accuracy of +/- 3 Hz
- Range provides information in terms of vocal performance and capability used in more realistic vocal conditions.
- Assessment stresses the vocal system by using vocal constraints
- Avoids the possibility of vocal abuse
While voice change often occurs during puberty without any residual voice problem, disturbed mutation can occur. Thee male subject retains a child-like, higher pitched voice post-puberty, resulting in a voice vs. age mismatch and pitch abnormality
This condition may also affect females. The female may also maintain a child-like voice post-puberty.
- Pitch abnormality may be less noticeable as compared to the male condition, since the female voice does not undergo as drastic a shift in pitch level
Excessive muscular activity in those muscles which increase the lengthening and tensing aspects of vocal folds function, the result may be an increase in pitch level.
- May have experienced this at times of emotional stress.
Cases of psychosis, schizophrenia, and clinical depression may be characterized in part by changes to the pitch of the voice.
- Habitual pitch may be lowered due to the increased mass of the vocal folds.
- Habitual pitch may be increased due to increased stiffness of the fold(s) and compensatory increased laryngeal tension.
- Habitual pitch may not be affected at all.
- Pitch variability may occur (ex. diplophonia, pitch breaks) due to altered vibratory characteristics.
- Monopitch and decreased pitch ranges may be observed due to restricted range of lengthening/tensing motion within the vocal folds
This is significantly lower in smokers vs. nonsmokers
- May be due to a thickening of the vocal folds and the connective tissue as a result of smoking.
