Your best session. Every time.

Speech Motor Chaining™ sessions quickly adapt in difficulty based on client progress. Speech Motor Chaining™ serves as your partner for clinical decisions that take a learner from establishing a speech sound to generalization.

Speech Motor Chaining™ does this by adapting several principles of motor learning:

Linguistic complexity of the practice trial (from syllables to sentences)
Ordered or random grouping of trials
Prosodic variation of trials
Amount of clinician feedback
Specificity of the clinician's feedback
Amount of self-monitoring

The efficacy of Speech Motor Chaining™ as an evidence-based solution is backed by several research studies:

Notice: No Speech Motor Chaining™ components or materials, including word lists and treatment structure, can be modified and/or redistributed under the name(s) "Speech Motor Chaining", "Speech Chaining", "Chains", or "Chaining" without express written consent from SpeechLink Incorporated. We do this because the scientific evidence only applies to Speech Motor Chaining™ as it is presented in the free Excel datasheets and the web application. Remixing and redistributing the material may invalidate the claims of evidence-based practice. Clinicians can use Speech Motor Chaining™ out of the box for treatment and clinical research. We welcome consultation with researchers interested in testing experimental modifications of Speech Motor Chaining™.
