HCRI Therapy Works Across Stuttering Types and Severities

You may wonder how the stuttering therapy program at Hollins Communications Research Institute (HCRI) can be effective with so many persons who stutter. After all, doesn’t each individual who stutters have a unique pattern of disfluencies?

HCRI’s 12-day therapy program is called the Hollins Fluency System III: High Definition Speech Reconstruction for Stuttering. It has proven effective in thousands of stuttering cases that range from mild to severe. What makes the stuttering therapy effective lies in understanding the common, central defining feature that is present among those with developmental stuttering. This feature involves muscle contractions that are not correct for the speech sounds being attempted.

These faulty contractions drive the speaker’s vocal tract into positions that are not correct for the speech sounds being attempted. There are many faulty vocal tract positions that can be seen across persons who stutter. After all, many different muscles can be involved in forcing the vocal tract into incorrect positions. Thus, observations of stuttering appear to indicate that different stutterers show idiosyncratic features in their disfluent speech. This would appear, at first, to represent a potential problem when it comes to treating stuttering.

However, the key to the success of the HCRI stuttering therapy program is that we all must share closely similar vocal tract positions in order to produce recognizable, fluent speech. The HCRI program, through precise, systematic training, brings each therapy participant’s muscle-force patterns and vocal tract shapes into conformance with those that are proven to generate fluent speech.

In effect, by understanding the essential defining features across those who stutter, it becomes possible for a single therapy to be highly effective with the many variations observed in stuttering.

How HCRI Therapy Works to Address the Central Defining Feature of Stuttering

As shared above, Hollins Fluency System III  helps clients with all forms of developmental stuttering learn how to replace faulty muscle contractions that cause stuttering with new muscle behaviors that generate fluent speech. By literally “reconstructing” muscle actions that drive movements of the tongue, lip, jaw, soft palette, and vocal folds, therapy participants can achieve and sustain the ability to speak fluently.

During HCRI’s 12-day stuttering therapy program, expertly trained clinicians work one-on-one with clients to instruct, evaluate and guide them through each tested step in the institute’s stuttering treatment system. In addition to personalized coaching, the use of proprietary computer software and a mobile app during therapy help make fluency acquisition easier and more precise. Post-therapy clinical support and a comprehensive package of practice tools help keep clients on track with fluency throughout their lives.

No other stuttering treatment replicates the sophistication of the Hollins Fluency System III therapy program – or the individualized approach from which clients benefit.

HCRI Stuttering Therapy Outcomes

Research studies demonstrated that 93% of therapy participants achieved fluency by the end of their 12-day program. These individuals represented a broad spectrum of stuttering types and severities. When evaluated two years after therapy, 75% of clients maintained their fluency using the skills acquired during HCRI therapy.

Jean DePiro Overcame Stuttering’s Debilitating Impact and Found Her Voice


Music served as a refuge for the young, gifted Jean DePiro who began stuttering before she entered grade school. To escape the relentless taunting from classmates and siblings, Jean would spend time alone playing piano and listening to music. She would also sing to herself, since the physical properties that drive stuttering are typically not present when someone sings.

While growing up, Jean’s stuttering inhibited her from participating in classroom discussions, making new friends, and engaging in social activities. Her speech condition eroded her confidence and made her reclusive.

“As a massive stutterer, I was miserable. I couldn’t pick up the phone and say hello. I couldn’t communicate with others. And, I simply shut down. Music was my only joy,” she said.

That all changed when Jean turned 17. Her parents learned about the pioneering work in stuttering therapy at Hollins Communications Research Institute (HCRI). HCRI’s research scientists had identified a new way to view and treat stuttering. The result was a transforming, immersion therapy that systematically teaches individuals how to use speech muscles in new ways to control stuttering and speak fluently.

Jean enrolled in the nonprofit center’s three-week program and began therapy with 10 other participants from across the country. She worked intensely each day under the guidance of the center’s clinicians. Her efforts paid off. By the end of treatment, Jean was able to speak fluently for the first time in her life. In addition, she was amazed by her ability to talk with ease when standing in front of other participants. Prior to HCRI, speaking before a group was a terrifying concept.

“I was in tears by what I had accomplished,” Jean explained. “When you struggle with stuttering for so many years and have it resolved in such a short time, it is an overwhelming experience.”

According to HCRI President Ronald L. Webster, Ph.D., “HCRI therapy is founded on science and tested with thousands of cases. Clients learn step-by-step exactly what they need to do with their speech muscles to achieve fluency. They are instructed by specially trained clinicians and use HCRI’s proprietary technology to make fluency acquisition easier, precise and long lasting.”

HCRI’s program, which is now 12 days in length, is effective across a wide range of stuttering types and severities. It yields proven, quantitative fluency outcomes. Research demonstrates that 93% of participants achieve fluent speech by the end of treatment and 75% sustain their fluency when evaluated two years later.

After Jean returned home from HCRI, she felt a new sense of freedom and potential. “My experience with HCRI therapy was life-changing,” she said. “For so long, I didn’t have a voice. Thanks to HCRI, now I do and I love to talk.”

More than three decades later, Jean continues to use the fluency skills she learned at HCRI. Her speech never holds her back from anything she wants to do. Music continues to play an important role in her life. She serves as the music director for a popular theatre house, as well as a church choir director and organist, while working in Revenue Cycle Training at the University of Virginia Hospital.

Moreover, she used her journey from stuttering to fluency to inspire a student she met at the University of Virginia. She shared her story and encouraged the student to seek HCRI stuttering treatment to help him realize his career dreams. He took her advice and is facing a future filled with opportunities through fluency.
