Background– speech and voice production Clients with motor speech and voice disorders have
impaired regulation of speech and voice production (programming and execution of speech motor movements).
Clinical examples Parkinson’s disease – reduced pitch variability Cerebral palsy – excessive pitch variability. Hyperfunctional dysphonia – excessive laryngeal
muscle tension.
Treatments target at training clients to (re) learn motor skills for effective speech and voice production.

An analogy is ……
e.g., the analogy between the heart and a pump
![Page 8: Application of implicit motor learning principles to ... · IHP Tara Whitehill SHS Estella Ma SHS Andus Wong Post-doctoral fellow Andy Tse Ph.D. candidate. 3 Background –speech](https://reader035.vdocuments.net/reader035/viewer/2022071216/60485e7921eb8e6df606cbd4/html5/thumbnails/8.jpg)
Advantages of analogy learning Easy to learn quickly. Performance is robust under stress. Learners are able to multi-task after training.

Practical (clinical application) Inform clinicians an intervention program that
can optimize clients’ learning of speech and voice production.
Theoretical Evaluate the universality of motor learning
theories.

Aim of study
To examine pitch variation in participants who received either analogy instructions or explicit instructions (modulating their intonation during speech production).
![Page 13: Application of implicit motor learning principles to ... · IHP Tara Whitehill SHS Estella Ma SHS Andus Wong Post-doctoral fellow Andy Tse Ph.D. candidate. 3 Background –speech](https://reader035.vdocuments.net/reader035/viewer/2022071216/60485e7921eb8e6df606cbd4/html5/thumbnails/13.jpg)

MethodologyStep I – Focus group for culturally appropriate analogies
of monotone, normal and excessive intonation.
Step II – 40 participants completed a speech task following either analogy or explicit instructions.

Moderate Pitch Variation
Monotone (Minimal) Pitch Variation
Explicit Instruction
Read aloud with moderate pitchvariation. That is, speak with neither excessive nor minimal changes in the highness or lowness of your voice.
Explicit Instruction
Read aloud with no pitchvariation. That is, speak without changes in the highness or lowness of your voice.

Demonstrated its benefits in speech learning.
Well-established advantages of analogy learning in sport learning.
