The purpose of this probe is to differentiate labial assimilation from fronting. Read
the following conditions and check which of the statements accurately describe the
response pattern that occurred in Checklist A and B.

Labial Assimilation is active when the following two conditions are met:

___ 40% or more of the targets in Checklist A are produced as labials, and one of the
following is met in Checklist B:

___ 70% or more of the targets are correct.

___ 70% or more of the targets are replaced by non-labial sounds.

___ 70% or more are a combination of correct targets or non-labial error productions.

Fronting is more likely to occur when 40% or more of the targets in Checklists A and B are produced
as labials.

The purpose of this probe is to differentiate velar assimilation from backing. Read the
following conditions and check which of the statements accurately describe the response
pattern that occurred in Checklist A and B.

Velar Assimilation is active when the following two conditions are met:

___ 40% or more of the targets in Checklist A are produced as velars, and one of the following
is met in Checklist B:
___ 70% or more of the targets are correct.
___ 70% or more of the targets are replaced by non-velar sounds.
___ 70% or more are a combination of correct targets or non-velar error productions.

Backing is more likely to occur when 40% or more of the targets in Checklists A and B are produced as
velars.
