Valsalva Stuttering Therapy is a comprehensive new approach to stuttering therapy, which seeks to improve fluency by controlling the physiological mechanism – the Valsalva mechanism – that may be involved in stuttering blocks.  Rather than teaching "fluency shaping" or focusing on controlling one's speech, Valsalva Stuttering Therapy is aimed at addressing the physiological, neurological, and psychological factors that interfere with the natural speaking ability that you already have Its goal is not artificial fluency, but freeing your natural speaking ability and making your speech easier, less effortful, and more enjoyable. 

The Standard Valsalva Stuttering Therapy Program includes 15 hours of therapy over a period of approximately 4 monthsThe therapy can be done  using Skype (depending on your location and subject to applicable law).  In addition to therapy sessions, participants must also do at least 30 minutes of practice every morning, plus other assignments.  Additional therapy is available, as needed.

Free video conferences are available for persons interested in therapy, depending on your location and applicable law. During the conference, other therapy arrangements may also be discussed.

Valsalva Stuttering Therapy addresses the physiological, neurological, and psychological aspects of stuttering, teaching effective new ways to:

  • Reduce the occurrence of stuttering blocks, and

  • Dissolve stuttering blocks when they occur, using  revolutionary new procedures.

Rather than focusing on "controlling" one's speech, Valsalva Stuttering Therapy promotes easy, natural speech by:

  • Relaxing the Valsalva mechanism,

  • Reducing the urge to exert effort,

  • Diverting effort impulses to a part of the Valsalva mechanism that does not interfere with speech,

  • Treating words as a continuous flow of movement and phonation, rather than as physical objects, and

  • Promoting the voicing of vowel sounds and self-expression through the music of your voice, so as to free your own natural speaking ability. 

Valsalva Stuttering Therapy intentionally does not emphasize "fluency" per se, because efforts to “stop stuttering” are usually self-defeating.  Natural fluency cannot be forced. Instead, the goal is to free you to express yourself in an easy, effortless, and natural way, thereby allowing natural fluency to follow on its own.

Valsalva Stuttering Therapy, in its current form, has been developed through actual clinical  experience, experimentation, and practice-based evidence, involving the participation of more than 200 persons who stutter from all over the world. Individualized counseling also helps you transfer Valsalva-relaxed speech to everyday speaking situations.

Valsalva Stuttering Therapy has been very effective in promoting easier, less effortful, natural-sounding speech in everyday speaking situations.

In order to allow the therapy sessions to focus more efficiently on your own specific needs, the therapy program is supplemented by the following Materials Package, which can be downloaded:

  • Extensive written exercise modules, totaling more than 200 pages.

  • An electronic version of William Parry's book, Understanding & Controlling Stuttering (4th Edition).

The time required to obtain optimal results will vary depending on each individual. However, the insights and skills learned from Valsalva Stuttering Therapy may enable you to achieve further progress on your own, while reducing the possibility of relapse. 


Free video conferences may be arranged for persons interested in therapy (depending on your location and applicable law.
