Recently, a stuttering correction device resembling a hat but functioning as a bone-conduction wearable was unveiled in China.
Stuttering, commonly known as stammering, refers to the repetition of sounds or interruptions in speech. It is a complex speech disorder involving genetics, neurological development, psychological stress, and linguistic behavior.
Currently, mainstream stuttering correction methods in China include articulation therapy, breathing techniques, hypnotherapy, and Morita therapy. These approaches typically require training in specialized language environments at professional institutions, causing significant inconvenience for stutterers. Moreover, correction effects often diminish or even reverse when individuals return to familiar settings.The Changboshi Stuttering Corrector encourages individuals to practice correction in their daily lives, ensuring that the effectiveness of the correction is not affected by changes in the linguistic environment.
Chang Doctor is China's new-generation stuttering corrector utilizing Delayed Auditory Feedback (DAF) technology. DAF is the mainstream stuttering correction technique in Western countries. Its remarkable feature is that wearers immediately feel the effect upon putting on the device—much like how vision becomes clear with the right glasses—resulting in instantly smoother speech.
Statistics show that stuttering symptoms can improve by over 80% after using DAF devices.
Long ago, people observed that when stutterers recite or speak the same passage simultaneously with another person, their stuttering miraculously disappears. This phenomenon is medically termed the "choral speech effect."Delayed Auditory Feedback (DAF) technology can be simply understood as a technical method that allows the stutterer to hear their own voice with a slight delay while speaking. This creates the scenario of "another person" speaking simultaneously with them, thereby enhancing the stutterer's speech fluency in a manner similar to the "choral speech effect"!
It is worth mentioning that the Changbo Doctor device appears as an ordinary hat, which holds revolutionary significance in the history of stuttering correction.Stutterers often possess strong self-esteem and are sensitive to the appearance of stuttering correction devices. The ordinary hat design achieves high concealment, allowing users to wear it without psychological pressure.
Dr. Chang employs bone conduction technology, eliminating the need for in-ear placement. With three frequency conversion modes, extended battery life, and lightweight, comfortable materials, it's suitable for all-day wear. This truly enables wear-and-use, use-and-wear functionality, allowing effortless stuttering correction anytime, anywhere.
