↵aRats produced composite calls in which multiple modules were produced during the same expiration (preceded by inspiration “A”) but were separated by a pause of laryngeal muscle EMG activity. N indicates the number of incompletely assembled composite calls found. Inspirations “A” were longer (duration) and deeper (pressure) than before uninterrupted composite calls (inspiration “B”). Inspirations before 20 utterances were averaged (mean ± SD).
