About our project

The problem we solve: Stuttering is a speech fluency disorder. Symptoms include repetition, prolongation or interruption of sounds. Today, stuttering effects more than 85 million people worldwide – regardless of language, geography, or ethnicity. In the US, more than 3.9 million are deeply affected by this huge impediment to conversation, to jobs, to love and connection to people that matter in their lives. 85% of stutterers in the US do not receive therapy at all due to frustrated and expensive experiences. You think you do not know a stutterer? Nicole Kidman, Emily Blunt, Rowan Atkinson (Mr. Bean), Samuel L. Jackson, Joe Biden, Bruce Willis are some of the famous stutterers. But there are even more!

About our solution: speechagain delivers Germany’s leading stuttering therapy method, invented by our Chief Medical Officer Dr. Alexander Wolff von Gudenberg, to tablets, smartphones and desktops. The speechagain digital therapy includes: - bio-feedback speech exercises powered by artificial intelligence - speech reconstruction training - non-avoidance therapy to integrate speechagain training to real life situations - outcome-based interactive video dialogues - analytics dashboard for user and parents progress tracking - self-motivating up-level gamification - extensive curriculum and exercise library.

Progress to date:

We have more than 100 users with phenomenal feedback. We won the HIMSS EUROPE Price in July 2017 with our solution.

How We Help Patients

We can make people stutter-free in weeks. They will stay stutter-free by using our web-based program constantly. - Better and cheaper, 24/7 available on any digital device!

Stuttering is in >50% of the cases combined (as a consequence, not the root cause) with psychosocial disorders. Many stutterers avoid communication.

speechagain provides the most effective evidence-based stuttering therapy by using artificial intelligence adopted to sound / speech technology. The users learn the speech techniques for soft onsets which give them the tools to overcome blockages.

How We Help Physicians

Physicians are mostly no experts in speech therapy. speechagain helps them to offer state of the art therapy. Patients are treated better and faster.

How We Help Hospitals

speechagain offers better and faster treatment for stutterers. Even so they are not treated in a hospital setting, hospitals can offer this service since stuttering is often a "comorbidity".

How We Help Partners

Partners can be schools, companies, public facilities, speech therapy organizations, stuttering supporting groups, healthcare provider or health insurance companies.

Our vision was and is to build the Doctor Algorithm - which means "the computer" become a specific therapist himself.

As a medical doctor with background in IT and business I wrote a book about big data in healthcare in 2014 (BIG DATA. Diagnosis, Therapy and Side Effects)

I met Alexander Wolff von Gudenberg, who is a MD as well and head of Europe´s largest stuttering therapy institute. We jointly share our goal to transfer their >20 years of experience and treating >3000 stutterers into the digital world!

We have an expert and PhD in algorithm bases sound recognition in our team as well as an enthusiastic speech therapist and healthcare manager. Our UX experts have worked in many projects in consumer industries - so we know how to make this happen!

Every person has a right to speak their mind and be heard. With your support we can change lives and make everyone be heard – clearly and effortlessly.
