Case Study – 9 Year Old Patient


The patient is a 9-year-old who began stuttering before the age of 4. In initial diagnosis, the patient demonstrated moderate to severe stuttering characterized by repetition and stress. At this stage, the patient’s speech efficiency (SES – Speech Efficiency Score) was measured at 77%, meaning that for 23% of speech time, the patient does not transmit new information due to stuttering.

Use of NiNiSpeech

The patient practiced with the NiNiSpeech app for 6 months. The therapist could also watch the results of the practice and listen to the exercises. On average, the patient practiced about 3 minutes each day. The speech-enhancing activities embedded in the NiNiSpeech app were adapted to the treatment stage according to the therapist’s instructions. The treatment began with self-practice, practice with the NiNiTeam, and, ultimately, practice with other users the patient’s age. Activities also included short reading assignments, subsequent questions and answers, spontaneous discourse, and time-pressured speech.

Treatment Results

After only 10 days of practice, there was already a noticeable improvement in speech. After six months of treatment and training with NiNiSpeech, the patient was able to raise his SES level to 93%, as shown in the figure.

In the feedback questionnaire, the patient noted that “Practicing with NiNiSpeech very much helped me improve my speech.”
