Monitoring metrical stress in polysyllabic words

This study investigated the monitoring of metrical stress information in internally generated speech. In Experiment 1, Dutch participants were asked to judge whether bisyllabic picture names had initial or final stress. Results showed significantly faster decision times for initially stressed targets (e.g., KAno ‘‘canoe’’) than for targets with final stress (e.g., kaNON ‘‘cannon’’; capital letters indicate stressed syllables). It was demonstrated that monitoring latencies are not a function of the picture naming or object recognition latencies to the same pictures. Experiments 2 and 3 replicated the outcome of the first experiment with trisyllabic picture names. These results are similar to the findings of Wheeldon and Levelt (1995) in a segment monitoring task. The outcome might be interpreted to demonstrate that phonological encoding in speech production is a rightward incremental process. Alternatively, the data might reflect the sequential nature of a

Rhymes will be argued later to replace the syllable as the prosodic unit that is the domain in certain phonological processes, and moras do not dominate strings of segments but rather single segments. However, see van Heuven (1994) on the possibility of single segments acting as prosodic domains in general. * Using this kind of structure meant that he could refer to the syllable as a unit, while in the same effort resolving the, at that time still troublesome, ambisyllabicity problem. This problem involves segments that phonologically belong to the two syllables between which they are CHAPTER 1 6 4 The bars over some of the vowels in (4) indicate length. phonotactic co-occurrence restrictions between them that do not hold between the other subsyllabic parts. A notorious example of such a restriction is the impossibility of the sequence "long vowel-velar nasal". Combinations like [o ], [i ] and [a ] are ill-formed in a large number of languages. Another argument for the constituency of nucleus and coda is of a more phonetic nature. A long history of experiments shows that there is a temporal relation between a vowel and a following consonant in a large number of languages (cf. Peterson & Lehiste 1960; Chen 1970). The experiments reveal some sort of "trade-off " relation between the nucleus and the coda, but not between the nucleus and the onset. For instance, long vowels are often followed by short consonants and short vowels by long consonants, and voiced consonants are preceded by longer vowels than voiceless consonants (cf. English bed vs. bet). These observations show that the durations of the nucleus and coda are interrelated. Following Lehiste's (1971) assumption that such temporal relationships between two segments reflect programming as a unit at some higher level, we insert a node called the rhyme under the syllable node (cf. Fudge 1969; Selkirk 1978). This new node dominates the nucleus and the coda, which results in the syllabic structure presented in (3).

An example of such a rule is provided by Lass (1984). He states that, in Old English noun declensions, the onset-rhyme division is needed to account for the presence of a suffix. Let us look at some of Lass' data. 4 (4) a.

He identifies 'loudness' as the acoustic correlate of stress. There is a, perhaps not so obvious, discrepancy between Sweet's definition of stress and his acoustic correlate. The effort with which breath is expelled is definitely speaker oriented, while loudness is a perceptually (read 'for the listener') defined property of speech that is correlated with the intensity of the speech signal. 5 This is probably what Jones (1950) had in mind when he introduced the distinction between stress (speaker activity) and prominence (effect perceived by the listener). 1 The experiments reported on in this chapter have been published in Goedemans & van Heuven (1993).

This paper investigates the interplay between the metrical structure and phonotactic complexity in English, a language with lexical stress and an elaborate inventory of consonant clusters. The analysis of a dictionary-and corpus-based list of polysyllabic words leads to two major observations. First, there is a tendency for onsetful syllables to attract stress, and for onsetless syllables to repel it. Second, the stressed syllable embraces a greater array of consonant clusters than unstressed syllables. Moreover, the farther form the main stress, the less likely the unstressed syllable is to contain a complex onset. This finding indicates that the ability of a position to license complex onsets is related to its distance from the prosodic head.

This study investigated the encoding of metrical information during speech production in Dutch. In Experiment 1, participants were asked to judge whether bisyllabic picture names had initial or final stress. Results showed significantly faster decision times for initially stressed targets (e.g., LEpel 'spoon') than for targets with final stress (e.g., liBEL 'dragon fly'; capital letters indicate stressed syllables) and revealed that the monitoring latencies are not a function of the picture naming or object recognition latencies to the same pictures. Experiments 2 and 3 replicated the outcome of the first experiment with biand trisyllabic picture names. These results demonstrate that metrical information of words is encoded rightward incrementally during phonological encoding in speech production. The results of these experiments are in line with Levelt's model of phonological encoding.

Two visual world experiments tested the hypothesis that expectations based on preceding prosody influence the perception of suprasegmental cues to lexical stress. Experiment 1 showed that phonemically overlapping words with different initial stress patterns compete for recognition. Experiment 2 further demonstrated that fundamental frequency and syllable timing patterns across material preceding the target word can influence the relative activation of competing alternatives with different initial stress patterns. The activation of alternatives with initial stress was higher when preceding stressed syllables had suprasegmental acoustic characteristics similar to the initial syllable of the target word. These findings suggest that expectations about the acoustic realization of an utterance include information about metrical organization and lexical stress, and that these expectations constrain the initial interpretation of suprasegmental stress cues. These results are interpreted as s...

Five experiments investigated the role of sublexical units in English single word production. L. Ferrand, J. Segui, and G. W. Humphreys (1997) reported a priming effect that was most effective when primes and targets shared the first syllable. Experiments 1A and 1B failed to replicate this effect but Experiment 1B showed that subsyllabic units play a role in speech production. This role was further explored using a picture naming task in Experiment 2. Naming latencies were shortest when the segmental overlap between prime and target (the picture name) was largest, regardless of the syllable structure of the target. Experiments 3 and 4 replicated this segmental overlap effect with different sets of words as targets. Experiment 5 showed that the magnitude of the overlap effect increased with longer prime exposure duration. The implications of these results for theories of phonological encoding in speech production are discussed.

Three experiments investigated the role of word stress and vowel harmony in speech segmentation. Finnish has fixed word stress on the initial syllable, and vowels from a front or back harmony set cannot co-occur within a word. In Experiment 1, we replicated the results of Suomi, McQueen, and Cutler (1997) showing that Finns use a mismatch in vowel harmony as a word boundary cue when the target-initial syllable is unstressed. Listeners found it easier to detect words such as HYmy in PUhymy (harmony mismatch) than in PYhymy (no harmony mismatch). In Experiment 2, words had stressed target-initial syllables (HYmy as in pyHYmy or puHYmy). Reaction times were now faster and the vowel harmony effect was greatly reduced. In Experiment 3, Finnish, Dutch, and French listeners learned to segment an artificial language. Performance was best when the phonological properties of the artificial language matched those of the native one. Finns profited, as in the previous experiments, from vowel harmony and word-initial stress; Dutch profited from word-initial stress, and French did not profit either from vowel-harmony or from word-initial stress. Vowel disharmony and word-initial stress are thus language-specific cues to word boundaries. ᭧ 1998 Academic Press One of the major issues in spoken word problem is to understand how listeners segment the continuous speech signal into dis-recognition concerns the detection of word boundaries in continuous speech.
