“…Some believed that the clue to overcome stuttering is by understanding the role of auditory information in organizing articulation . Reporting the use of DAF in a 49-year-old man who started to stutter after traumatic brain injury, the results of Van Borsel et al, (2010) Kaspar & Rübeling (2011) supports the hypothesis. According to Kaspar & Rübeling, rhythm seems to be a significant criterion of speech monitoring, and hence a mismatch between spoken words and auditory feedback realized by DAF induces obvious speech problems on rhythmic level regardless of phonemic discrepancy at the same time.…”

“…Mainly, these are: factors inherent to the client such as gender, age, stuttering severity, disfluency pattern, origin of stuttering, and biological subtype; factors outside the client including delay time, intensity, manner of delivery, speech mode, and speech situation; possible side-effects like a reduction in speech rate, an increase of speaking fundamental frequency and vocal intensity, lengthening of vowels, and a possible effect on speech naturalness. Other factors are in a way or another related to cosmetics, finances, and the long-term effect (Van Borsel et al, 2007).…”

Background: With the tremendous improvements in technology in producing new techniques to overcome stuttering, many assumptions were stated from different aspects. Aims:To in/validate some of the stuttering assumptions, the present study attempts to investigate the role played by Delayed Auditory Feedback (DAF) device in overcoming stuttering and improving stutterers' fluency. Methods:A client study of MO, a 23-year old bilingual student who exhibits stuttering and language delay due to psychological factors. An intensive therapeutic treatment which continued for 20 months has been given to the client at hand. The client had to practice (in English) ten(10) alphabetical characters, twenty (20) words (10 nouns and 10 verbs), and ten (10)sentences for four continuous hours every day. Results:The analyses of the client's utterances throughout five entire sessions show that his rate of speech became slower if not almost normal across increases in DAF. The findings reveal that simultaneous application of both treatments on speaking through DAF was successful in reducing the rate of stuttering in the speech of the client under investigation. It all depends on age, determination, the level of severity, and the way he/she uses DAF. These findings account for the results that support many theories of stuttering including Phonemic Content Theory, Covert Repair Hypothesis (CRH) and Johnson's theory. Taken together, these results weigh strongly against the hypothesis stated that stutterers have generally high levels of emotional reactivity (e.g., Brutten/Shoemaker, 1967).

“…Frequent exercises help in such situation to accrue a long-lasting effect of improving the flow of speech. The DAF is still used in speech disfluency therapy, often in combination with other methods such as filtered feedback (FAF) [7][8][9][10][11][12][13].…”

Abstract:The paper describes an application that allows to use a humanoid robot as a stutterer's assistant and therapist. Auditory and visual feedback has been used in the therapy with a humanoid robot. For this purpose, the common method of "echo" was modified. The modification is that the speaker hears delayed speech sounds uttered by the robot. The sounds of speech coming from an external microphone are captured and delayed by a computer and then, using User Datagram Protocol (UDP), sent to the robot's system and played in its speakers. This system allows the elimination of negative feedback and external sound field's noise. The effect of this therapy is enhanced by the fact that, in addition to the effect, relating to the action of the delayed feedback, the speaker has company during the difficult process of speaking. Visual feedback has been realized as changes in the robot's hand movements according to the shape of the speech signal envelope and possibility of controlling speech with a metronome effect.
