The article presents an analysis of duration of periods and glottal articulation changes between the release of the word closure and voice onset time in English as considered in phonetics. For quotation type of words the stop closure is distinct, creating a greater time interval which helps distinguish the two phonemes clearly. In normal course of speech, the stop closure is not complete, leading to a smaller interval time and even overlapping along the dimension of voice onset time. In case of a stressed syllable or the syllables in final sentence, stress tends to create a longer voicing lag. The role of contextual features responsible for apparent overlap of dimension along the voice onset time in running speech needs to be explored further.
