  Konkani is a highly nasalised language which makes it unique among Indo-Aryan
languages. This work investigates the acoustic-phonetic properties of Konkani
oral and nasal vowels. For this study, speech samples from six speakers (3 male
and 3 female) were collected. A total of 74 unique sentences were used as a
part of the recording script, 37 each for oral and nasal vowels, respectively.
The final data set consisted of 1135 vowel phonemes. A comparative F1-F2 plot
of Konkani oral and nasal vowels is presented with an experimental result and
formant analysis. The average F1, F2 and F3 values are also reported for the
first time through experimentation for all nasal and oral vowels. This study
can be helpful for the linguistic research on vowels and speech synthesis
systems specific to the Konkani language.
