Are the postvocalic /r/ and /l/ in bar /bar/ and ball /bal/ part of a complex vowel, like the glide in buy /bay/, or part of the syllable coda, like the stop in bought /bat/? Are syllabic /r/ and /l/ vowels or consonants? A corpus of 6200+ speech errors was examined. Vowel + glide acts as a unit in errors, while vowel + consonant rarely does so. Vowel + /r/ and vowel + /l/ were intermediate, often acting as units, often not. Unlike consonants, /r/ and /l/ are a part of the syllable nucleus, but, unlike glides, are not a part of the vowel. Syllabic /r/ and /l/ show the error patterns of both vowels and consonants. They are syllabic consonants rather than vowels, but show vowel error patterns by virtue of their syllabicness and sharing many features with vowels.

The test contains 101 words of different length, including 71 words with sibilants and affricates. Systemic processes are the most frequent phonological processes, among them alveolo-palatalization.

Yet, phonological intervention aims to accelerate the acquisition of both speech-sounds and word structure, such as word length, stress or shapes in CV sequences. Until normative studies and meta-analyses provide in-depth information on this topic, smaller investigations can provide initial benchmarks for clinical purposes. To provide preliminary reference data for word structure development in a variety of Spanish with highly restricted coda use: Granada Spanish (similar to many Hispano-American varieties). To be clinically applicable, such data would need to show differences by age, developmental typicality and word structure complexity. Thus, older typically developing (TD) children were expected to show higher accuracy than younger children and those with protracted phonological development (PPD). Complex or phonologically marked forms (e.g. multisyllabic words, clusters) were expected to be late developing. Participants were 59 children aged 3-5 years in Granada, Spain: 30 TD children, and 29 with PPD and no additional language impairments. Single words were digitally recorded by a native Spanish speaker using a 103-word list and transcribed by native Spanish speakers, with confirmation by a second transcriber team and acoustic analysis. The program Phon 1.5 provided quantitative data. In accordance with expectations, the TD and older age groups had better-established word structures than the younger children and those with PPD. Complexity was also relevant: more structural mismatches occurred in multisyllabic words, initial unstressed syllables and clusters. Heterosyllabic consonant sequences were more accurate than syllable-initial sequences. The most common structural mismatch pattern overall was consonant deletion, with syllable deletion most common in 3-year-olds and children with PPD. The current study provides preliminary reference data for word structure development in a Spanish variety with restricted coda use, both by age and types of word structures. Between ages 3 and 5 years, global measures (whole word match, word shape match) distinguished children with typical versus protracted phonological development. By age 4, children with typical development showed near-mastery of word structures, whereas 4- and 5-year-olds with PPD continued to show syllable deletion and cluster reduction, especially in multisyllabic words. The results underline the relevance of multisyllabic words and words with clusters in Spanish phonological assessment and the utility of word structure data for identification of protracted phonological development.

The current article reports pilot Spanish data for this study from two 4-year-old boys with protracted phonological development. The purposes of the pilot study were to: (1) develop and evaluate a word list for elicitation that could be used across Spanish dialects and that sufficiently sampled Spanish word lengths, stress patterns, word shapes and phonemes; and (2) to derive hypotheses for the larger study, based on patterns found in these children's speech, and a review of the literature. The two speakers showed some developmental patterns reported for other languages (e.g. constraints on production of liquids and word-initial consonants in unstressed syllables) but also patterns that may reflect Spanish phonological inventories, allophony and frequencies. These data helped consolidate the Spanish word list for elicitation and led to questions for the ongoing study concerning word structure, multisyllabic words, liquids, fricatives and vowel sequences.

Children's pronunciations of words are often quite different from those of adults. The child pronunciations may diverge notably from the target adult phonology, but in ways that make sense from a cross-linguistic perspective on the phonological systems of adult languages.

Inhibitory effects of large neighbourhoods have been argued to underlie apparent anti-frequency effects, whereby high-frequency default features are more prone to mispronunciation errors than low-frequency nondefault features. Data from the original SLIPs experiments that found apparent anti-frequency effects are analysed for neighbourhood effects. Effects are facilitatory: errors are significantly less likely for words with large numbers of neighbours that share the characteristic that is being primed for error ("friends"). Words in the neighbourhood that do not share the target characteristic ("enemies") have little effect on error rates. Neighbourhood effects do not underlie the apparent anti-frequency effects. Implications for models of speech production are discussed.

While there is evidence for the storage of larger stretches of speech, a separate issue is how much such stored forms contribute to processing, as compared to morphologically simpler forms. We examine the acquisition of one aspect of the phonology of Valley Zapotec: complementarity of segmental length based on subsegmental features: vowels before fortis consonants are short (VCː), and vowels before lenis consonants are long (VːC). This complementarity is found for fortis consonants in morphologically simple forms with final stress (simple nouns, verbs with full subject noun), but not in morphologically complex forms with a final unstressed syllable (diminutive nouns, verbs with pronominal subject clitic). During one period of development, Zapotec-learning children overgeneralize the complementarity from morphologically si...
