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.
