Improving Speech Recognition for the Elderly: A New Corpus of Elderly Japanese Speech and Investigation of Acoustic Modeling for Speech Recognition (2020.lrec-1)
Copied to clipboard
| Challenge: | In an aging society, a highly accurate speech recognition system is needed for use in electronic devices for the elderly but this cannot be achieved using conventional speech recognition systems due to the unique features of the speech of elderly people. |
| Approach: | They construct a new corpus of elderly Japanese speech from existing Japanese speech corpora and train them using existing data. |
| Outcome: | The proposed models achieve word error rates (WER) as low as 13.38%, exceeding the results of the previous study. |
Elderly Conversational Speech Corpus with Cognitive Impairment Test and Pilot Dementia Detection Experiment Using Acoustic Characteristics of Speech in Japanese Dialects (2022.lrec-1)
Copied to clipboard
| Challenge: | Several studies have explored using only the acoustic and linguistic information of conversational speech as diagnostic material, with some success. |
| Approach: | They propose to use acoustic features of conversational speech to detect dementia even when dialects are present. |
| Outcome: | The proposed method detects dementia using acoustic features even when dialects are present even when spoken from two regions. |
