The present study proposes a methodology to carry out an exploratory analysis of the interlanguage (IL) prosody of English learners whose native language (L1) is Chilean Spanish or French. Our aim is to describe the regularities and differences in the way that students perform focus in oral speech. By doing this, we seek to determine if the prosody of the learners’ L1 has an impact on their intonation of English as a foreign language, and to understand the link that exists between their conception of focus in English and the use they make of it. We specifically worked with the duration and f0 values, which we modelled with the Momel algorithm. Results show intonational trends within groups of speakers of the same L1 associated to the shape and the range of their tonal movements.
