However, these models based on a hybrid method require a forced aligned Hidden Markov Model(HMM) state sequence obtained from the GMM-based acoustic model. Therefore, it requires a long computation time for training both the GMM-based acoustic model and a deep learning-based acoustic model. In order to solve this problem, an acoustic model using CTC algorithm is proposed. CTC algorithm does not require the GMM-based acoustic model because it does not use the forced aligned HMM state sequence. However, previous works on a LSTM RNN-based acoustic model using CTC used a small-scale training corpus. In this paper, the LSTM RNN-based acoustic model using CTC is trained on a large-scale training corpus and its performance is evaluated. The implemented acoustic model has a performance of 6.18% and 15.01% in terms of Word Error Rate(WER) for clean speech and noisy speech, respectively. This is similar to a performance of the acoustic model based on the hybrid method.展开更多

We analyzed the data of the Childhood Autism Rating Scale (CARS) of 44 students at the high school course of a special needs education school who participated in agricultural vocational training. The data were divided into two groups according to the scores of “General Impressions”, one of 15 question items of the CARS: one was the group whose score was 1 (usual), and the other was the group whose scores were 1.5 to 4 (unusual). The results of the Mann-Whitney U test showed significant differences between two groups in eight items including “Relating to People” (p Relating to People” with six other items. As a result, “Relating to People” was considered to be the most effective item to know the participant’s autistic characteristics at a very early stage of training. Eventually, adding two items, “Body Use” and “Imitation” which are necessary to master agricultural tasks, to “Relating to People”, we proposed three indicators.展开更多
