Area of Science:

Speech-Language Pathology
Acoustic Analysis
Biofeedback Technology

Background:

Speech sound difficulties affect many individuals, necessitating effective therapeutic interventions.
Residual /ɹ/ distortions present a common challenge in speech therapy.
Visual-acoustic biofeedback (VAB) offers a novel approach to address these challenges.

Purpose of the Study:

To summarize current practices in visual-acoustic biofeedback (VAB) for speech sound disorder treatment.
To focus on clinical strategies for improving residual /ɹ/ distortions.
To provide guidelines for clinicians utilizing VAB.

Main Methods:

Review of evidence on VAB characteristics and beneficial populations.
Guidelines for using VAB to match acoustic representations.
Emphasis on the clinical application of linear predictive coding (LPC) spectrum.

Main Results:

Successful VAB implementation depends on clinician/client understanding of acoustic representations.
Appropriate selection of acoustic targets, templates, and articulatory strategies is crucial.
Effective feedback models and practice schedules scaffold new speech sound acquisition.

Conclusions:

Integrating VAB into clinical practice expands intervention options for speech sound disorders.
VAB facilitates improved speech sound acquisition and generalization.
This approach offers a valuable tool for speech-language pathologists.
