Not only are there internal factors that play a role in the voice changing there are also physical factors, depending on the height and weight of an individual that could affect the tone, pitch and frequency. The purpose of this assignment was to better understand these differences. As defined in our class manual, voice onset time (VOT) refers to the time difference between a voiced stop closure and a voiceless stop. It is determined by the articulatory blockage at the beginning of vocal fold vibration for the following vowel. Among the various factors of VOT variations include; phonetic context, place of articulation, speech tempo, and speakers’ gender. For voiceless stops, women display longer VOT than men. For voiced stops however, the results are rather mixed. Which makes sense if you look at the characteristics of mine and Marks h-d words, you will notice there are multiple differences within our tokens regarding formant frequencies. However we show similarities with our durations. So I wondered at first if this had anything to do with the tokens being the same word, or if it was the vowel production. Differences between the speech of men and women relates to the formant patterns associated with vowel production. Although men have low frequency vowel formants than women, the differences in
