Study Notes
Speech Signal Features
- Speech signal features can be instrumental or visual.
- Instrumental features include breathing, resonance, articulation, and voice.
- Visual features include kinematic and aerodynamic characteristics.
Perceptual Speech Assessment
- Perceptual speech assessment is based on distinctive speech characteristics.
- Mayo clinic classification of dysarthria (DAB) is based on perceptual speech assessment.
- The Mayo Clinic classification of dysarthria considers 38 speech characteristics.
- The Mayo Clinic classification of dysarthria considers 38 speech characteristics that fall into different categories.
Speech Assessment Tasks
- Vowel prolongation is assessing how long a person can say "ah" steadily and clearly.
- Parameters measured in vowel prolongation include pitch, loudness, voice quality, and breath support.
- Alternating motion rates (DDK) assesses speed and regularity of articulator movements.
- The DDK task assesses articulatory precision.
- Sequential motion rates (SMRs) assesses rapid sequential movement from one articulatory position to another.
- Speech production at word and sentence level assesses articulation.
- Picture description assesses articulation, it may reveal imprecise bilabial sounds if the person has lip weakness.
- Connected speech assessments assess articulation and resonance.
- Resonance assessments include: asking the person to say “u” with a mirror under the nose and asking the person to differentiate between phonemes "nay/bay" and "may/pay".
- Prosody assessments focus on: dysprosody, monotonous speech, uneven and equal stress patterns in speech, and intonation.
Instrumental Speech Evaluation
- Instrumental speech evaluation visually displays and quantifies frequency, intensity and temporal components of speech.
- Computerised Speech Lab (https://www.youtube.com/watch?v=2yO3JZB-yvU) is an example of instrumental speech evaluation.
Formal Dysarthria Assessment
- Frenchy Dysarthria Assessment (FDA) assesses cough reflex, swallow reflex, drool at rest, breathing at rest and during speech, lip function in various movements, jaw function, palate function, laryngeal function, tongue function in various movements, and intelligibility.
- Assessment of Intelligibility of Dysarthric Speech (AIDS) quantifys single-word intelligibility, sentence intelligibility, and speaking rate.
- Sentence Intelligibility Test (SIT) assesses the intelligibility of sentences, the test can be administered by a clinician or through a computer.
- Word Intelligibility Test (WIT) assesses the intelligibility of individual words, the test can be administered by a clinician or through a computer.
- Robertson Dysarthria Profile assesses a wide variety of speech and oral motor functions.
Assessment of Intelligibility, Comprehensibility, and Efficiency (ICE)
- Intelligibility is the accuracy with which an acoustic signal is conveyed by the speaker and recovered by the listener.
- Comprehensibility is the extent to which a message can be understood by the listener within a communication context.
- Efficiency is the overall effectiveness of communication.
Intelligibility Measurement
- Index of severity assesses the severity of a speech impairment.
- Index of functional limitation assesses the impact of a speech impairment on a person’s ability to communicate.
Comprehensibility
- Comprehensibility includes: semantic, syntactic, and physical contexts.
- It is influenced by a wide range of factors beyond the speech signal itself.
Communication Effectiveness Survey (CES)
- The CES measures a person’s perception of their own speech difficulties.
Severity Rating of Functional Speech
- ASHA NOMS Motor Speech Workshop: rates the severity of a person's speech problems and identifies areas for therapy intervention.
- Therapy Outcome Measure (TOM) Activity Scale: Dysphasia/Aphasia measures the functional impact of dysarthria on a person’s ability to communicate.
