The extent and degree of utterance-final word lengthening in spontaneous speech from 10 languages.

Words in utterance-final positions are often pronounced more slowly than utterance-medial words, as previous studies on individual languages have shown. This paper provides a systematic cross-linguistic comparison of relative durations of final and penultimate words in utterances in terms of the degree to which such words are lengthened. The study uses time-aligned corpora from 10 genealogically, areally, and culturally diverse languages, including eight small, under-resourced, and mostly endangered languages, as well as English and Dutch. Clear effects of lengthening words at the end of utterances are found in all 10 languages, but the degrees of lengthening vary. Languages also differ in the relative durations of words that precede utterance-final words. In languages with on average short words in terms of number of segments, these penultimate words are also lengthened. This suggests that lengthening extends backwards beyond the final word in these languages, but not in languages with on average longer words. Such typological patterns highlight the importance of examining prosodic phenomena in diverse language samples beyond the small set of majority languages most commonly investigated so far.

Repetition Reduction Revisited: The Prosody of Repeated Words in Papuan Malay.

It has frequently been shown that speakers prosodically reduce repeated words in discourse. This phenomenon has been claimed to facilitate speech recognition and to be language universal. In particular, the relationship between the information value of a word in a discourse context and its prosodic prominence have been shown to correlate. However, a literature review provided in this paper reveals that most evidence comes from English, where prosodic marking of information status often coincides with repetition reduction. The current study investigates to what extent repetition reduction occurs in Papuan Malay, spoken in the western part of the island of New Guinea (Indonesia). The work on Papuan Malay prosody available to date suggests fundamental differences compared to English and other Germanic languages. An acoustic analysis is carried out on repeated words in short stories produced by native Papuan Malay speakers. The results show that upon repetition, words were shortened and produced with higher F0. In a subsequent word identification task, it was found that first and second mentions were equally intelligible. Conclusions partially confirm previous work and challenge theories on how the prosody and information value of a word are related.
