Embodiment Construction

[0013] The definition of pronunciation onset time (VOT) refers to the time distance between the voice of the subsequent vowel after the release of the stop sound and the vibration of the voice of the subsequent vowel. In domestic Chinese studies, this indicator is mostly used to analyze the difference between stop sounds and voiced stops. In foreign countries, VOT is also an important indicator for studying the intelligibility of a speaker's pronunciation. This patent proposes a new acoustic reference standard to evaluate the degree of impairment of the pronunciation of deaf-mute patients, that is, articulatory organ onset time (AOT), which is defined as the articulatory organ (such as the tongue) is ready to speak from the rest to the beginning of the voice. The time interval between vibrations. Compared with the original VOT, the acoustic parameter AOT is generally applicable to all pronunciations. There is no significant difference in the VOT value of the same pronunciation...

Abstract

The invention relates to the fields of medical treatment and education for disabled people, in particular to a method for judging the degree of hearing impairment of deaf-mute patients. A method for judging the degree of hearing impairment of deaf-mute patients, using a three-dimensional electromagnetic pronunciation instrument to obtain the pronunciation start time of the pronunciation organs and the start time of the pronunciation organs of multiple normal people when they read the test corpus, and the deaf-mute patients to be judged read through the three-dimensional The electromagnetic pronunciation instrument obtains the pronunciation start time of the corresponding pronunciation organ and the pronunciation start time of the pronunciation organ when the deaf-mute patient to be judged reads the test corpus, and compares the two to judge the degree of hearing impairment of the deaf-mute patient.

Description

technical field [0001] The invention relates to the fields of medical treatment and education for disabled people, in particular to a method for judging the degree of hearing impairment of deaf-mute patients. Background technique [0002] Medical care and education for the disabled has always been an area that our country attaches great importance to. In recent years, scientific research has gradually shifted to helping groups in need. For deaf-mute patients, the reference standard for measuring the degree of articulation impairment is usually the acoustic parameter voice onset time (VOT), which is used to reflect the speaker's coordination skills in the study of Mandarin pronunciation, but not Works with all pronunciations. [0003] In the literature "Voice onset time of alveolar stop / t / and realization of unaspirated affricates associated with Mandarin-speaking children with repaired cleft palate", Chenghui Jiang et al. The relationship between phonetic features and pro...
