Abstract:The detection of hearing recognition ability of hearing impaired children mainly adopts the Mandarin version of Lin's seven-tone manual detection method in China, which has problems such as low speed and time-consuming. In response to these problems, a method for machine recognition of the Mandarin version of Lin's seven-tones is proposed to detect hearing impaired children's auditory recognition ability in this paper. A Gaussian Mixture Model is presented, which was trained using the constructed Lin's seven-tone dataset. The comparison experiments with the Hidden Markov Model were provided. And three indicators, i.e., precision, recall and accuracy are used to evaluate these two models. The experimental results show that the Gaussian mixture algorithm outperforms the hidden Markov algorithm in three indicators, and can better realize the recognition of the Mandarin version of Lin's seven-tone test.
