This paper presents findings from a phonetic study of voiced and voiceless stops. To distinguish voiced and voiceless stops, we have to measure three parameters, namely the vowel length, duration of CVC syllables and voice onset time (VOT) of the word-initial consonants. For measuring the vowel length and gap duration, we considered 10 voiced (/b, d, d., g, d3/) and voiceless (/p, t, t., k, t /) stop consonants and two abutted vowels /a/ and /i/. For measuring voice onset time, we considered 3 voiced (/b, d., g/) and voiceless (/p, t., k/) stop consonants. These sounds were recorded with the help of GOLDWAVE software in the sound proof lab at C-DAC (Centre for Development of Advanced Computing), NOIDA. The utterances were acoustically analyzed via PRAAT. The values of target stops were obtained from the waveform and verified with the spectrogram. The wide band spectrograms and text grids were plotted by using "PRAAT" software.
