The purpose of this study was to explore the Spectral times of the Broca's Aphasic patients' stops caused by a stroke. A survey was conducted on 5 Broca's Aphasic patients and 7 people in control group. Spectral times were analized using Praat (version 4.4.22) and a microphone (shure PG48) was directly connected to a notebook PC for recording. The results were as follows: 1) The Broca's Aphasic patients' VOT, post-vowel length and utterance length of whole word were longer than those of the control group. 2) The VOT of the control group and the Broca's Aphasic patient group showed a significant difference in all of bilabial consonants, alveolar consonants, velar consonants and fortis consonants. The VOT lengths of the control group were all shorter than those of the Broca's Aphasic patient group.
