Longitudinal changes in polysyllable maturity of preschool children with phonologically-based speech sound disorders.

Children's polysyllables were investigated for changes in (1) consonant and vowel accuracy, (2) error frequency and (3) polysyllable maturity over time. Participants were 80 children (4;0-5;4) with phonologically-based speech sound disorders who participated in the Sound Start Study and completed the Polysyllable Preschool Test (Baker, 2013) three times. Polysyllable errors were categorised using the Word-level Analysis of Polysyllables (WAP, Masso, 2016a) and the Framework of Polysyllable Maturity (Framework, Masso, 2016b), which represents five maturity levels (Levels A-E). Participants demonstrated increased polysyllable accuracy over time as measured by consonant and vowel accuracy, and error frequency. Children in Level A, the lowest level of maturity, had frequent deletion errors, alterations of phonotactics and alterations of timing. Participants in Level B were 8.62 times more likely to improve than children in Level A at Time 1. Children who present with frequent deletion errors may be less likely to improve their polysyllable accuracy.

Speech production abilities of 4- to 5-year-old children with and without a history of late talking: The tricky tyrannosaurus.

Purpose: Research on the speech production abilities of children with a history of late talking (HLT) is limited. We compared 4- to 5-year-old children with and without a HLT on a routine speech assessment and a single-word polysyllable assessment.Method: The two speech assessments were administered to 13 children with a HLT (4;4-5;9 years) and 11 children with a history of typical development (HTD) (4;1-5;10 years). Data were analysed using descriptive and inferential statistics.Result: The HLT group had significantly poorer speech accuracy than the HTD group on both the routine speech and polysyllable assessments. The HLT group also showed a significantly higher percentage occurrence of consonant omissions on both speech assessments compared to the HTD group. Descriptive analysis of participants' polysyllable productions indicated that the HLT group showed a higher percentage occurrence of a range of error types compared to the HTD group.Conclusion: By 4-5 years of age, children who were late to talk had speech production abilities that were significantly poorer than their peers who were not late to talk, suggesting continued underlying differences.

Polysyllable productions in preschool children with speech sound disorders: Error categories and the Framework of Polysyllable Maturity.

PURPOSE: Children with speech sound disorders (SSD) find polysyllables difficult; however, routine sampling and measurement of speech accuracy are insufficient to describe polysyllable accuracy and maturity. This study had two aims: (1) compare two speech production tasks and (2) describe polysyllable errors within the Framework of Polysyllable Maturity. METHOD: Ninety-three preschool children with SSD from the Sound Start Study (4;0-5;5 years) completed the Polysyllable Preschool Test (POP) and the Diagnostic Evaluation of Articulation and Phonology (DEAP-Phonology). RESULT: Vowel accuracy was significantly different between the POP and the DEAP-Phonology. Polysyllables were analysed using the seven Word-level Analysis of Polysyllables (WAP) error categories: (1) substitution of consonants or vowels (97.8% of children demonstrated common use), (2) deletion of syllables, consonants or vowels (65.6%), (3) distortion of consonants or vowels (0.0%), (4) addition of consonants or vowels (0.0%), (5) alteration of phonotactics (77.4%), (6) alteration of timing (63.4%) and (7) assimilation or alteration of sequence (0.0%). The Framework of Polysyllable Maturity described five levels of maturity based on children's errors. CONCLUSIONS: Polysyllable productions of preschool children with SSD can be analysed and categorised using the WAP and interpreted using the Framework of Polysyllable Maturity.

A Text Mining Approach to the Text Difficulty of Latin American Peace Agreement / "Una aproximación por minería de texto a la dificultad textual de los acuerdos de paz en Latinoamérica"

Abstract A peace agreement was recently subjected to a plebiscite as a solution to finish the Colombian armed conflict. With 62.57% of abstention, 18.44% of the Colombian electorate rejected this agreement. This paper aims to propose a methodological approach that shows how to linguistically analyze peace agreements as political products that are acceptable or not according to their text difficulty. Given the socio-political similarities of the armed conflicts of Colombia, Guatemala, and El Salvador, we scrutinized with sufficient computational detail these peace agreements. The results revealed that the text difficulty of these accords was more appropriate for a person with at least 19 years of education, suggesting that these sort of texts are not written for broader and less-educated audiences.

Resumen El gobierno de Colombia sometió recientemente a plebiscito un acuerdo de paz para dar por finalizado su conflicto armado. Para este plebiscito la abstención electoral fue del 62.57% y solo el 18.44% de los votantes rechazó la implementación del acuerdo. El objetivo de este trabajo es proponer una aproximación metodológica que muestre cómo analizar los acuerdos de paz como productos políticos que pueden ser aceptables o no según su dificultad textual. Dadas las semejanzas socio-políticas de los conflictos armados en Colombia, Guatemala y El Salvador, en este trabajo se muestra con suficiente detalle computacional el análisis por minería de texto de los acuerdos de paz celebrados en estos países. Los resultados revelaron que la dificultad textual de estos acuerdos exige un nivel educativo de al menos 19 años de educación formal, lo que sugiere que ese tipo de documentos no suelen redactarse para audiencias más numerosas con menores niveles de educación formal.
