example

[0070] External stutter and normal speech signals were generated and compared for effectiveness. The incongruent speech signal was used in order to compare the intrinsic incongruent properties of externally stuttering speech with the characteristics of incongruent fluent speech (in which the second speech signal contained different phonological material than was read by the participant), to It is determined whether a reduction in fluency is achieved, and which components of the inconsistent second speech signal may have contributed to the reduction in stuttering (or the improvement in fluency). Thus, natural classification schemes for vowels and consonants were examined with dynamic and relatively static vocal tract positions. Experiment I involved meaningful speech: normal continuous speech, normal staccato speech, stuttering continuous speech, and stuttering staccato speech. Experiment II involves vowels and consonants: / a / , / a-i-u / , / s / , / s-sh-f / .

Abstract

Methods and devices (10) generate an exogenous natural speech signal (10s) as an auditory stimulus to a user to enhance the fluency of persons who stutter. The natural speech signal (10s) is independent of the contemporaneous speech production of the stutterer and is provided by a voice gesture and can be a prolonged or sustained voice gesture sound such as a simple vowel, or consonant, or vowel trains and the like. The second speech signal (10s) can be transmitted in advance of a speaking event or speech production of the stutterer and / or concurrently with a speaking event, either intermittently or continuous during the speaking event. The devices (10) of the instant invention are configured to provide the voice based speech signal (10s) such that it is audible to the user and does not require feedback of the user s own speech allowing the user to speak at a substantially normal pace with enhanced fluency. The device (10) and methods can relay the signal (10s) based on a manual activation or automatically based on a detection of speech or a stuttering event on the part of the user.

Description

field of invention [0001] The present invention relates to devices and methods for improving fluency in people who stutter. Background of the invention [0002] Traditionally, stuttering has been treated with several different treatment methods, including psychotherapy, drug therapy, and the use of altered auditory feedback produced by electrical signal processing devices delivered to the stutterer. These techniques can generally be described as internal changes in the output of the speech signal, such as prolonged or slowed speech, rhythmic speech, signs, and labial sounds, or as external dynamic changes in the speech signal itself, both of which can be successfully used in stutterers Produces smoother speech. See e.g. "A Guide to Stuttering" by O. Bloodstein (5 th ed. Singular, San Diego, CA, 1995). [0003] We believe that external auditory perception of speech such as reading in unison, masking speech, delayed auditory feedback, and frequency-changed feedback is more...
