Due to its interaction with the sound segments, prosody is one of the elements to be considered when investigating foreign accent. In this study, the speech patterns of a dialogue read by two Brazilians and two Americans are contrasted, and two prosodic elements are investigated: rhythm and intonation. Speech rhythm, which refers to a temporal patterning of elements in the flow of speech, plays a relevant role in discourse. Intonation, the melody of speech, organizes the flow of speech and expresses modalities, emotions and attitudes. In the case of L2 speakers, it is very likely that certain prosodic patterns of L1 will be transferred to L2. In this study, the rhythmic and intonational patterns of a read dialogue are contrasted through acoustic-phonetic analysis by means of the PRAAT software. The acoustic data comprises duration measuraments of V-V units, syllables, feet and adjacent full vowels, as well as pitch accent markings. The analysis of the rhythm of American English is mainly based on Bolinger&#8223;s Pitch Accent Theory. ToBI (Tones and break índices) is used for the tonal labelling, and ANOVA and the variability index for the statistical treatment of the data. Results point to significant differences (p<.05) in syllable and V-V unit duration means, and differences in the variability index of the syllabic feet. The rhythmic structure of the utterances produced by the Brazilian subjects was affected by L1 transfer of tonicity, juncture, vowel quality as well as processes of segmental reduction and elision. As regards intonation, it was observed, in the productions of the American subjects, a systematic occurrence of the phenomenon of downstep, and, in the productions of the Brazilian subjects, a productive occurrence of L*+H e L+H* tones, which affected the production of meaning. With this study, I wish to contribute to the research on the teaching of rhythm and intonation to Brazilian speakers of English
