Use this resource to help document articulatory errors in American Sign Language. The creation of this document was a collaborative effort by a deaf linguist, a hearing (signing) speech-language pathologist, and a hearing (signing) occupational therapist.

With this document, practitioners will be able to:

Identify which articulators are implicated

• Hands, arms, wrist, fingers, torso, and face/head

Determine which component of articulation is affected

• Handshape formation

• Place of articulation

• Path movement

Describe the articulation error in a standardized way

• Use language that can be understood across disciplines (Appendix E)

Note: Production errors can be linguistic-based (phonological) or motor-based (articulatory); this document focuses on motor-based articulation errors in ASL.
