Enhancing Language Learners’ Comprehensibility through Automated Analysis of Pause Positions and Syllable Prominence

Résumé

This research paper addresses the challenge of providing effective feedback on spontaneous speech produced by second language (L2) English learners. As the position of pauses and lexical stress is often considered a determinative factor for easy comprehension by listeners, an automated pipeline is introduced to analyze the position of pauses in speech, the lexical stress patterns of polysyllabic content words, and the degree of prosodic contrast between stressed and unstressed syllables, on the basis of F0, intensity, and duration measures. The pipeline is applied to 11 h of spontaneous speech from 176 French students with B1 and B2 proficiency levels. It appeared that B1 students make more pauses within phrases and less pauses between clauses than B2 speakers, with a large diversity among speakers at both proficiency levels. Overall, lexical stress is correctly placed in only 35.4% of instances, with B2 students achieving a significantly higher score (36%) than B1 students (29.6%). However, great variation among speakers is also observed, ranging from 0% to 68% in stress position accuracy. Stress typically falls on the last syllable regardless of the prosodic expectations, with the strong influence of syllable duration. Only proficient speakers show substantial F0 and intensity contrasts.
