For Dutch, F0 variation, intensity and duration are the main cues for accentuation in normal speech. As esophageal (E) and tracheo-esophageal (T-E) speakers have reduced control over these parameters, accentuating words may be problematic. Normal and (T-)E speakers read paired sentences, differing only with regard to the accentuation of content words. In a listening experiment, it was found that the percentage correctly identified accent was above chance for each speaker group, although lower for E speakers than for normal and T-E speakers. Acoustic analyses showed that most (T-)E speakers used the same parameters as normal speakers to indicate accent, although the individual acoustic profiles of alaryngeal speakers varied considerably. In alaryngeal speakers, estimated F0 and perceived pitch frequently mismatched, suggesting that some of them produced pitch through an alternative system, which may serve as a permanent substitute for F0, or as a back-up if and when control over F0 falters.
