Purpose of study
Purpose of Study

Principles/universals principled descriptions

of normally of disordered sound

developing sound systems

systems

  • to see how they overlap

  • are they part of the same system? (delayed)

  • are they separate? (deviant)


3 parts of the study
3 parts of the study:

  • Phonetic inventory

    • 5 characteristic inventory types

    • implicational laws

  • phonotactic constraints

  • compared to normals


Importance of article
Importance of Article

  • Provided a framework for disordered systems using independent analyses

    • described commonalities of disordered sound systems

    • disordered sound systems are principled (non-random)

    • disordered systems similar to normal systems

  • can identify “delayed” versus “deviant”

  • provided information on tx options


Importance of article1
Importance of Article

  • When you use principles that are formulated in terms of distinctions, rather than in sounds, able to capture commonalities across individuals

  • There is no specification of the range and limits of variation of the basic properties of a sound system

    • therefore, we can’t compare to normal systems to see if disordered systems correspond to normal systems


On the lawfulness of change in phonetic inventories

Therefore, the purpose of the study was to examine the phonetic inventories in order to establish the range and limits of variation of disordered sound systems


Implicational laws phonetic inventory
Implicational Laws phonetic inventories in order to establish the range and limits of variation of disordered sound systems(phonetic inventory)

  • If you have [lateral] or [strident] distinction --> liquid

    ([nasal] distinc)

    LEVEL E LEVEL D

  • If you have liquid ([nasal] distinction) -->frics OR affr

    LEVEL D LEVEL C

  • If you have frics OR affr --> voiced and voiceless obs

    LEVEL C LEVEL B


Implicational laws phonetic inventory1
Implicational Laws phonetic inventories in order to establish the range and limits of variation of disordered sound systems(phonetic inventory)

  • If you have [voice] distinction ->(a) coronal [coronal] distinc

    among anterior obstruents

    (b) nasal and glides

    [sonorant] [consonantal]

    LEVEL B LEVEL A


How do disordered sound systems fit with normally developing systems
How do Disordered Sound Systems “Fit” with Normally Developing Systems?

  • Stops, nasals, glides (Level A) acquired before fricatives, affricates, liquids (Level C - E)

  • anterior sounds (Level A) acquired before nonanterior sounds (Level B)

  • voice distinction acquired relatively early (Level B)


On the lawfulness of change in phonetic inventories

Implications for intervention Developing Systems?:If you treat sounds that are phonetically complex (i.e., higher levels), you may not need to treat intermediate levels since they are implied through linguistic principles- they will be acquired on own without direct treatment
