This study looks at affective meanings of two features of New Zealand English associated with opposing pitch extremes: Uptalk with high pitch and creaky voice with low. In a matched-guise experiment, listeners of different ages were asked to rate short speech samples from young women containing uptalk and creaky voice on a series of affective meaning scales. Results showed that while uptalk was rated more negatively overall, ratings largely aligned with predicted iconic associations of pitch for each scale. However, there were differences by listener age, especially for creak. We argue these results show that the availability of iconic associations of pitch depends on social factors such as the listeners' beliefs and experience, such as group differences related to age, which affect the seeming naturalness of a given iconic link.</p>","PeriodicalId":51255,"journal":{"name":"Language and Speech","volume":" ","pages":"238309251314863"},"PeriodicalIF":1.1,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143494532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a systematic production study investigating whether Persian speakers distinguish between three focus structures on target words that bear a pitch accent, that is, broad, narrow, and corrective focus. In a multidimensional phonetic analysis, we investigated the parameters of intensity, duration, and F0. Taking a local perspective, results show that the duration of the target word is a robust cue for focus marking in both syllables of the word, exhibiting a three-step pattern (corrective > narrow > broad). In the first syllable, intensity is a reliable cue to distinguish broad focus from the other two focus types, with higher intensities in broad focus. In the accented syllable, a different two-step pattern is observed, with narrow and corrective focus showing larger F0 spans than broad focus. Taking a global perspective that considers the parts of the utterance before and after the target word, we find a lowering of F0 and decreased intensity for narrow and corrective focus in the pre-target region. In the post-target region, we find strong evidence for differences in mean F0 and intensity with lower F0 in corrective focus than in broad and narrow focus, while the intensity is lower in narrow and corrective focus than in broad focus.

Building upon previous research on phonological templates, we explored how systematicity based on such templates, whether they encode meanings or not, influenced word learning in preschool-age Hebrew-speaking children. We examined form-meaning systematicity, where words share phonological templates and carry similar categorical meanings of manner-of-motion (e.g., <i>finupál</i> and <i>bizudáx</i> carry the meaning of skipping), and form-only systematicity, where words are phonologically similar but do not share a meaning (e.g., <i>finupál</i> and <i>bizudáx</i> belong to different categories of manner-of-motion). We aimed to discern how these systematicity types impact the learning of the meaning of the word as a whole, that is, the encoding of visual form combined with manner-of-motion. Using novel Semitic-like stimuli, our experiments demonstrated that different types of systematicity involve different effects on word learning. Experiment 1 showed that form-meaning systematicity hindered the learning of the manner-of-motion. In contrast, Experiment 2 revealed that form systematicity facilitated learning these features. The findings suggest a complex interplay of top-down and bottom-up processes in word learning, expanding our understanding of systematicity in word learning.</p>","PeriodicalId":51255,"journal":{"name":"Language and Speech","volume":" ","pages":"238309241312983"},"PeriodicalIF":1.1,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143061395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research on Hebrew language development suggests early sensitivity to frequently occurring templates. For the Arabic dialects, little is known about whether implicit sensitivity to non-concatenative morphology develops at a young age through exposure to speech, and how templatic the spoken language is in comparison to MSA. We focus on Lebanese Arabic. We hypothesized that prolonged contact with French and English may have \"diluted\" the salience of roots and patterns in the input. We used three different corpora of adult-directed-speech (ADS), child-directed-speech (CDS), and child speech. We analyzed the root and pattern structures in the 50 most frequent Lebanese Arabic word types in each corpus. We found fewer words with templatic patterns than expected among the most frequent words in ADS (35/50), even fewer in CDS (23/50) and still fewer in the children's target words (15/50). In addition, only a minority contains three root consonants in their surface forms: 22 in ADS, 15 in CDS, and only 7 in words targeted by the children. We conclude that Semitic structure is less evident in either input to children or words targeted by children aged 1-3 than has been assumed.

Cross-linguistically, SCs consist of similar as well as distinct variants. However, in the study of SC learning, the effect of the similarity between the corresponding variants remains understudied. The salience hypothesis proposes that distinct dialect variants are more salient and learnable, while the learning bias hypothesis in phonological learning predicts that SC patterns with similar variants are preferred by learners. We conducted an artificial language learning experiment to test how sound similarity affects SC learning. Specifically, the degrees of similarity between variants were evaluated from multidimensional metrics, including phonetic and phonological measures, which are cross-validated with typological evidence. While there was no effect of variant similarity in learning simple one-to-one SCs, a preference for the most distinct dialect variant was found in the learning of SCs exhibiting more complex mapping structures (i.e., two-to-one and one-to-two). Our results confirm a preference for distinct variants in SC learning, although this effect relies on two conditions. First, the preference for distinction emerges only in the presence of complex mapping structures. Second, this preference requires an activation threshold, in that the distance of the SC must be sufficiently large to trigger the effect.</p>","PeriodicalId":51255,"journal":{"name":"Language and Speech","volume":" ","pages":"238309241308171"},"PeriodicalIF":1.1,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142985381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"文学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We compared production patterns in an auditory word-repetition task (without orthographic input) with those in a word-reading task. We analyzed the formant values (F1, F2, F3) of the schwa realizations of two groups of Austrian high-school students who had been learning French for 1 and 6 years. The results show that production patterns are more likely to be affected by L1 grapheme-to-phoneme correspondences when orthographic input is present.
