Abstract

In Brain Computer Interfacing (BCI), speech imagery is still at nascent stage of development. There are few studies reported considering mostly vowels or monosyllabic words. However, language specific vowels or words made it harder to standardise the whole analysis of electroencephalography (EEG) while distinguishing between them. Through this study, we have explored significance of chaos parameters for different imagined vowels chosen from International Phonetic Alphabets (IPA). The vowels were categorised into two categories, namely, soft vowels and diphthongs. Chaos analysis at EEG subband levels were evaluated. We have also reported significant contrasts between spatiotemporal distributions with chaos analysis for activation of different brain regions in imagining vowels.
