Speech Paralinguistic Approach for Detecting Dementia Using Gated Convolutional Neural Network
share
We propose a non-invasive and cost-effective method to automatically detect dementia by utilizing solely speech audio data without any linguistic features. We extract paralinguistic features for a short speech utterance segment and use Gated Convolutional Neural Networks (GCNN) to classify it into dementia or healthy. We evaluate our method by using the Pitt Corpus and our own dataset, the PROMPT Database. Our method yields the accuracy of 73.1 using an average of 114 seconds of speech data. In the PROMPT Database, our method yields the accuracy of 74.7 improves to 79.0 evaluate our method on a three-class classification problem in which we included the Mild Cognitive Impairment (MCI) class and achieved the accuracy of 60.6
