| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We present in this paper an end-to-end speech recognition system for a Japanese person with an articulation disorder resulting from athetoid cerebral palsy. The movements of such speakers are limited by their athetoid symptoms, and their utterances are often unstable or unclear, which makes it difficult for them to communicate. Therefore, the performance of automatic speech recognition (ASR) systems for people with an articulation disorder degrades significantly. Recently, deep learning approaches to speech recognition have seen much progress. These techniques require a large amount of training data, however, the amount of data from people with articulation disorder is limited due to their athetoid symptoms. This paper proposes a data augmentation method using not only the speech data of a Japanese person with an articulation disorder but also the speech data of a physically unimpaired Japanese person and a non-Japanese person with an articulation disorder. We employ an end-to-end ASR model based on the listen, attend and spell (LAS) model which has an acoustic module and a language module. In our proposed model, the acoustic module is shared between people with dysarthria, and a language module is assigned to each language regardless of dysarthria. The effectiveness of this approach was confirmed through word-recognition experiments where our proposed method outperformed a method based on the conventional LAS model. | |
