Design method and application of a closed speech audiometry vocabulary

Abstract

The invention discloses a design method and application of a close type speech audiometry vocabulary. The design method of the close type speech audiometry vocabulary comprises the steps of of 1, that the close type speech audiometry vocabulary comprises K vocabularies is set, wherein each vocabulary comprises H testing groups, the testing groups comprise testing items and confusing items, the length of the vocabulary is H, and H is any positive integral; 2, according to principles of shortness, phonemic balance, common use, coverage and equivalence, the K vocabularies are compiled in the step 1; 3, the close type speech audiometry vocabulary is calculated; 4, a testee conducts speech audiometry in a relatively quiet environment; 5, the audiometry is finished; 6, audiometry result calculation is conducted through a speech audiometry system according to the following steps.

Description

technical field [0001] The invention relates to the technical field of speech audiometry, in particular to a design method and application of a closed speech audiometry vocabulary. Background technique [0002] The Chinese Speech Hearing Assessment is based on the subject's ability to hear and distinguish sounds, syllables, vocabulary or sentences, and evaluates the subject's hearing level. In daily life, syllables are the most basic unit of speech communication and comprehension, so speech hearing assessment based on syllables is the most commonly used audiometry method. [0003] Syllable-based speech hearing assessment includes audiometric materials composed of syllables and corresponding audiometric systems and methods, and is divided into open and closed. At present, most of the Chinese speech audiometry adopts the open-ended audiometry method, and seldom uses the closed-ended audiometry method. In the open speech audiometry, the subject cannot complete the audiometry ...

AI Technical Summary

Problems solved by technology

This design method compiles confusion items from the phoneme level, but does not consider the perceptual characteristics of each phonetic unit at the syllable level

Moreover, the audiometric vocabulary used in Chinese speech audiometry is currently mostly compiled manually. The production cycle of high-quality audiometric vocabulary is long, and it is difficult to achieve global optimization.
