Isolated Bengali Vowel and Word Speech Sounds

This dataset includes two separate datasets---one for vowel and another for words. Seven isolated Bengali vowels (/অ/ [/ɔ/], /আ/ [/a/], /ই/ [/i/], /উ/ [/u/], /ঋ/ [/ri/], /এ/ [/e/], /ঐ/ [/oi/]) and seven isolated Bengali words (বোতল, বন, কপি, দোকোন, শেষ, সঠিক, উপরে) were collected at Khulna University of Engineering and Technology, Khulna 9203, Bangladesh. We collected these speech sounds from twenty male and female volunteers (age 20-26 years) having Bengali as their first language. We guided the speakers to pronounce each vowel and word in a different local accent along with a normal accent. Thus, we produced 40 data in each class of the two datasets, i.e., each of the vowel classes (অ, আ, etc.) contains 40 data and each of the word class (বোতল, বন, etc.) also contains 40 data.
