Mastering R Therapy: Effective Strategies, Activities, and Techniques for Speech Therapy Success

The English /r/ phoneme presents unique challenges in speech-language therapy due to its complexity, requiring meticulous coordination of intricate tongue movements. Effective remediation depends heavily on clinicians' understanding of how this phoneme functions in various contexts. Specifically, clinicians must clearly distinguish between prevocalic and vocalic contexts to tailor their therapeutic approaches precisely. This guide offers clinicians structured insights into these contexts, effective strategies for remediation, and clearly highlights expert-led webinars available at Speech Therapy PD, providing actionable resources for successful /r/ intervention.

Tongue Control for Speech Production & How to Facilitate it

Close your eyes, focus intra-orally, and count from 1 to 10 out loud. Carefully notice the presence of your tongue up within the dental arch and except for the occasional lowering for a vowel or a “th” your tongue-sides remain faithfully in contact with the top, side teeth. As you may know, this is the tongue’s “bracing” or “lateral margin stabilization.” This must-have lingual-dental anchorage helps to provide stability for front-tongue vertical movement of “n, t, d, s, z, sh, zh, ch, j, and l

The field of speech and language pathology all began in the 18th century when James Ford first advertised his services to address “stammering and other impediments in speech.” With speaking ability and diction being markers of English class during this time, Ford made a name for himself and opened the door for other early teachers. In America, the focus on stuttering and its treatments continued with the publication of Doctor Samuel Potter’s thesis on “speech and its deficits,” which he eventua

Even when comparing the percentage from 2002 which showed males accounted for 4.7 percent of certified SLPs, there has been a slight decrease. Why the rarity?

More Tips for "Th": Contracting & Moving, and f/th Suggestions (3 of 4)

As mentioned in the prevous post, “th” requires whole-tongue tension. Internal tension provides internal stabilization. We’re not talking super-tight tension, but enough contraction to move the tongue anteriorly-posteriorly with control, then posture, and interact spatially with the top incisors as air flows through. Also, last week’s tasks focused on building the capability to control and discern tight from loose, i.e., big swing, super-tight to super loose. The tension needed for a controlle

Mastering R Therapy: Effective Articulation and Carryover Techniques

The /r/ sound is one of the most challenging phonemes for speech-language pathologists (SLPs) to teach and for clients to master. It occurs in multiple positions within words, varies significantly across dialects, and requires precise tongue positioning that can be difficult to describe and demonstrate. Pam Marshalla, a renowned SLP and pioneer in articulation and motor speech therapy, dedicated much of her career to refining techniques for successful /r/ therapy.This blog post will explore the key principles of effective /r/ therapy, drawing directly from Marshalla’s teachings. We will examine why the /r/ sound is particularly difficult, the primary tongue positions for producing /r/, and proven techniques to help clients achieve correct production and carryover into everyday speech. If you're an SLP seeking practical, research-backed strategies, this post will serve as a valuable resource.

Mastering Carryover in Speech Therapy: Strategies for Lasting Success

Carryover is a crucial yet often overlooked aspect of speech therapy. Many Speech-Language Pathologists (SLPs) focus on sound acquisition and structured practice but struggle with ensuring that these learned skills transfer to natural conversation. Without effective carryover, even the most well-executed therapy sessions may fail to result in lasting speech improvements.This blog post explores the challenges of carryover and provides practical strategies to help SLPs foster consistent, independent speech production outside of the therapy room. By understanding the factors that contribute to carryover difficulties and implementing structured interventions, SLPs can equip their clients for success in real-world communication.

The 12 Functions of Echolalia

For many years, echolalia—the repetition of words or phrases—was viewed as an obstacle to communication rather than a meaningful step in language development. Traditional speech therapy approaches often attempted to reduce or eliminate echolalia, assuming it was a barrier to independent speech. However, research and lived experiences have shown that echolalia plays a crucial role in language development, particularly for gestalt language processors.

Gestalt Cognitive Processing & Advocacy Through the Eyes of an Autistic SLP

Language development is often viewed through the lens of analytic language processing, where children acquire language by learning individual words first and gradually building phrases and sentences. However, for some individuals—particularly autistic children—language is acquired differently. Gestalt Language Processing (GLP) is an alternative language development pathway in which children learn language in chunks or scripts before breaking it down into smaller, flexible units.
