Speech Science Test 3 Week 15 1St Powerpoint

Front 1

Speech ____________ and speech _______________ are complex systems

Back 1

production, perception

Front 2

What are some subsystems of the speech production and speech perception systems?

Back 2

respiratory, phonatory, articulatory, auditory, nervous systems

Front 3

A statement about a particular phenomenon, incorporating underlying principles, facts, and assumptions

Back 3

theories

Front 4

Theories are subject to change as a result of the development of ___________________ theories

Back 4

new/modified

Front 5

Simplification of a system that can be manipulated in a controlled manner

for ex: May include physical, physiological or mechanical version of the system to be tested

Back 5

models

Front 6

What are the three major issues related to organization and regulation of speech motor control
that are addressed by models and theories of speech production?

Back 6

1. The serial order issue
2. Degrees of freedom
3. Context-sensitivity problem

Front 7

Describes problems in speech that arise due to the fact that speech is a sequence of elements.

ex: /k/, /t/, /ae/ used as cat, tack, act

Back 7

The serial order issue

Front 8

What is the serial order issue?

Back 8

Elements could be specific features of a sound (ex; voicing or nasality), phonemes, syllables, parts of syllables etc

Front 9

Describes the movement of one structure (muscles of respiratory, laryngeal and articulatory subsystems) of a subsystem in relation to another (ex: lower lip and jaw can/not be in phase).

Back 9

degrees of freedom

Front 10

What is a degree of freedom?

Back 10

The way that each different potential muscular contraction in a system.

Front 11

The _______________________________ system must regulate all the muscular contractions (rapid movement and correct sequences) of all the speech subsystems to generate the target sounds and words

Back 11

speech motor

Front 12

What is the context-sensitivity problem?

Back 12

One speech sound can be produced in several different ways- this variability is production is a central factor of speech motor regulation

Front 13

Provide an example of the context sensitivity issue.

Back 13

Coarticluation is an integral aspect of speech production that results in variability in production of a target sound.
