Biofeedback system for correction of nasality

917 阅读 2020-02-11 16:04:57 上传

A method is described for correcting and improving the functioning of certain devices for the diagnosis and treatment of speech that dynamically measure the functioning of the velum in the control of nasality during speech. The correction method uses an estimate of the vowel frequency spectrum to greatly reduce the variation of nasalance with the vowel being spoken, So as to result in a corrected value of nasalance that reflects with greater accuracy the degree of velar opening.
