PURPOSE: this paper submits a study on the duration of the different phases of stops produced by two children, one of them with phonological disturbance (speaker 2). METHODS: the corpus includes 54 real words, with stop consonants in initial, medial and final position. In this study two of European Portuguese (EP) native speakers, aged between seven and eight years, took part. RESULTS: the results for the EP speaker 1 showed that the total duration of voiceless stop consonants was greater than voiced stop consonants. The VOT was, in general, larger for voiceless stops than in voiced stop consonant. Speaker 2 (with phonological disorder) devoiced the stop [g], and the stop consonant [d] was devoiced in initial position and voiced in medial and final position. The stop consonant [b] was normally voiced. CONCLUSION: most of the analyzed durations show similar values for both speakers.
