The purpose of the Iowa Articulation Norms Project and its Nebraska replication was to provide normative information about speech sound acquisition in these two states. An assessment instrument consisting of photographs and a checklist form for narrow phonetic transcription was administered by school-based speech-language pathologists to stratified samples of children in the age range 3–9 years. The resulting data were not influenced by the demographic variables of population density (rural/urban), SES (based on parental education), or state of residence (Iowa/Nebraska); however, sex of the child exerted a significant influence in some of the preschool age groups. The criteria used to determine acceptability of a production appeared to influence outcomes for some speech sounds. Acquisition curves were plotted for individual phoneme targets or groups of targets. These curves were used to develop recommended ages of acquisition for the tested speech sounds, with recommendations based generally on a 90% level of acquisition. Special considerations were required for the phonemes /n s z/.

Normal-speaking and speech-defective children were compared on a speech-sound identification task which included sounds the speech-defective subjects misarticulated and sounds they articulated correctly. The identification task included four tests: [r]-[w] contrasts, acoustically similar contrasts, acoustically dissimilar contrasts, and vowel contrasts. The speech sounds were presented on a continuum from undistorted signals to severely distorted speech signals under conditions which have caused confusion among adults. Subjects included 15 normal-speaking kindergarten children, 15 kindergarten children with defective [r]s, and 15 preschool-age children. The procedure employed was designed to test, in depth, each sound under study and to minimize extraneous variables. Speech-sound identification ability of speech-defective subjects was found to be specific rather than a general deficiency, indicating a positive relationship between production and identification ability.

This paper presents the Croatian version of the Multilingual Assessment tool for Narratives (MAIN), outlines its development and describes the research that has used it to assess narrative skills in monolingual and bilingual speakers. The Croatian version of MAIN has so far been used in three research projects and results have been presented in five peer-reviewed articles (published or in press) covering a total of 175 children in the age range from 5;0 to 9;0 (20 with developmental language disorder) and 60 adults, age range from 22 to 76. The accumulated results indicate that MAIN can differentiate narrative skills of speakers in distinct age groups and can distinguish children with language disorders form children with typical language development.

The competence in identifying and comprehending the meaning of idiomatic expressions developed at an early age. However, second language learners reach the comprehension skill differently within the age and at pace. There are many unresolved questions regarding the age which children start to comprehend L2 idioms. The objective of this study was to investigate the age at which children in Moi primary school in Nairobi were able to identify and comprehend the meaning of English idioms. The 60 participants were selected using purposive sampling. The children were divided into three age groups: 5-8 years old, 9-12 years old, and 13-16 years old. The participants were balanced in gender and level of formal education. They were asked to identify the correct non-literal meaning of the 20 idioms presented. It was reported that the group with an age range from 5-8 years old scored the lowest among the other.The findings showed that as early as five years of old (preschool age), children begin to understand some kinds of idiomatic expressions and that such ability slowly develops throughout childhood. At the age of 9, children mainly interpreted idioms literally. By the age of 12, they started to understand the non-literal meanings of idiomatic expressions correctly and continued to expand until the age of 16. It implied that age is a factor in the comprehension of idioms among children. Therefore, exposure to language input is vital in the process of early acquisition. The study provides pedagogical observation on early language acquisition. This study also assists the language teachers and language practitioners and material developers in decision making that lead to the development of a better curriculum.

Objective: Cortical auditory-evoked potentials (CAEPs), an objective measure of human speech encoding in individuals with normal or impaired auditory systems, can be used to assess the outcomes of hearing aids and cochlear implants in infants, or in young children who cannot co-operate for behavioural speech discrimination testing. The current study aimed to determine whether naturally produced speech stimuli /m/, /g/ and /t/ evoke distinct CAEP response patterns that can be reliably recorded and differentiated, based on their spectral information and whether the CAEP could be an electrophysiological measure to differentiate between these speech sounds.Method: CAEPs were recorded from 18 school-aged children with normal hearing, tested in two groups: younger (5 - 7 years) and older children (8 - 12 years). Cortical responses differed in their P1 and N2 latencies and amplitudes in response to /m/, /g/ and /t/ sounds (from low-, mid- and high-frequency regions, respectively). The largest amplitude of the P1 and N2 component was for /g/ and the smallest was for /t/. The P1 latency in both age groups did not show any significant difference between these speech sounds. The N2 latency showed a significant change in the younger group but not in the older group. The N2 latency of the speech sound /g/ was always noted earlier in both groups.Conclusion: This study demonstrates that spectrally different speech sounds are encoded differentially at the cortical level, and evoke distinct CAEP response patterns. CAEP latencies and amplitudes may provide an objective indication that spectrally different speech sounds are encoded differently at the cortical level.

Background. Soil-transmitted helminths (STH) are a public health problem in Kenya. The primary control strategy for these infections is preventive chemotherapy (PC) delivered through school based deworming (SBD) programs. The World Health Organization (WHO) recommends the inclusion of other at-risk groups in the PC. The untreated groups in endemic areas have been shown to act as reservoirs for STH transmission. Few field based studies have focused on the possible benefits of SBD to the untreated groups in the community. This study sought to determine the levels of STH among all age groups in a community where SBD has been going on for more than 10 years. Methods. This was a cross sectional study where 3,292 individuals, ranging from 2 to 98 years, were enrolled. Stool samples were analyzed using duplicate Kato Katz thick smear technique for presence of STH eggs. Statistical analysis was conducted using STATA software 14.0 (Stata corporation). Results. Out of the total 3,292 stool samples analyzed, only 13 were positive for any STH. Of these, 12 were infected with Trichuris trichiura and one case was of hookworm. There was no Ascaris lumbricoides infection detected. Of the 13 STH infections, seven of the infections were of school going age (6-18 years), 5 were of preschool age (<6 years), and one was of adult age group (18>). More male (61.5%) than female were infected with STH. Conclusion. This study shows very low prevalence of STH among all age groups in Mwea, suggesting that long term SBD may also be benefitting the untreated groups in the community and thus the potential to achieve STH elimination in such endemic areas.

Objective: The goal of this work is the creation of word lists, in Ilocano, suitable for use in speech audiometry.   Methods: First, estimates of the distribution of speech sounds and of the most common syllable structures in Ilocano were found from a phonetic transcription analysis of nearly 3000 words obtained from three magazine articles. Second, 372 two-syllable words were rated, for commonness, by fifteen native speakers of Ilocano who currently reside in Hawai’i. Finally, various combinations of two-syllable words were made to produce 50-item lists.   Results: First, an estimate of the distribution of speech sounds in Ilocano was found, with frequencies of occurrence ranging from 22.4%, for the speech sound /a/, to 0.007%, for the speech sound /v/. The syllable-structure analyses revealed that a very small number of distinct monosyllabic words were used very frequently. Two-syllable words were also used frequently, but were attributed to many distinct words. Second, from the rating results, approximately 70% of the two-syllable words in the rating survey were judged as common by 12 or more of the raters. Finally, four lists of 50 words each were constructed using only common two-syllable words with the most frequent two-syllable structures found in Ilocano. Each word list has a distribution of speech sounds that approximates that found from the phonetic analysis, and hence each list is roughly phonetically-balanced.   Conclusions: These word lists may be of value to otolaryngologists and audiologists who work with native speakers of Ilocano.   Keywords: Ilocano, Ilokano, phonetically-balanced, speech audiometry, word lists

Purpose The purpose of this study was to determine the extent to which school-age children with speech sound disorder (SSD) exhibit concomitant reading difficulties and examine the extent to which phonological processing and speech production abilities are associated with increased likelihood of reading risks. Method Data were obtained from 120 kindergarten, first-grade, and second-grade children who were in receipt of school-based speech therapy services. Children were categorized as being “at risk” for reading difficulties if standardized scores on a word decoding measure were 1 SD or more from the mean. The selected predictors of reading risk included children's rapid automatized naming ability, phonological awareness (PA), and accuracy of speech sound production. Results Descriptive results indicated that just over 25% of children receiving school-based speech therapy for an SSD exhibited concomitant deficits in word decoding and that those exhibiting risk at the beginning of the school year were likely to continue to be at risk at the end of the school year. Results from a hierarchical logistic regression suggested that, after accounting for children's age, general language abilities, and socioeconomic status, both PA and speech sound production abilities were significantly associated with the likelihood of being classified as at risk. Conclusions School-age children with SSD are at increased risk for reading difficulties that are likely to persist throughout an academic year. The severity of phonological deficits, reflected by PA and speech output, may be important indicators of subsequent reading problems.

Homework Completion

Purpose This study investigated the extent to which speech-language pathologists (SLPs) facilitate parents' completion of homework activities for children with speech sound disorder (SSD). In addition, this study explored factors related to more consistent communication about homework completion and strategies considered particularly effective for supporting this element of parental involvement. Method Licensed SLPs serving at least one child with SSD were invited to participate in an online survey. Questions relevant to this study gathered information regarding (a) frequency of communication about homework distribution and follow-up, (b) demographic and workplace characteristics, and (c) an open-ended question about the specific strategies used to support parental involvement and completion of homework activities. Results Descriptive results indicated considerable variability with respect to how frequently SLPs engaged in communication about homework completion, but that school-based SLPs were significantly less likely to engage in this type of follow-up. Strategies considered effective, however, were similar across therapy contexts. Conclusion These results suggest potentially important differences between school-based services and therapy in other contexts with respect to this particular aspect of service provision for children with SSD.

Objective: This study presents a novel approach for early detection of cognitive impairment in the elderly. The approach incorporates the use of speech sound analysis, multivariate statistics, and data-mining techniques. We have developed a speech prosody-based cognitive impairment rating (SPCIR) that can distinguish between cognitively normal controls and elderly people with mild Alzheimer's disease (mAD) or mild cognitive impairment (MCI) using prosodic signals extracted from elderly speech while administering a questionnaire. Two hundred and seventy-three Japanese subjects (73 males and 200 females between the ages of 65 and 96) participated in this study. The authors collected speech sounds from segments of dialogue during a revised Hasegawa's dementia scale (HDS-R) examination and talking about topics related to hometown, childhood, and school. The segments correspond to speech sounds from answers to questions regarding birthdate (T1), the name of the subject's elementary school (T2), time orientation (Q2), and repetition of three-digit numbers backward (Q6). As many prosodic features as possible were extracted from each of the speech sounds, including fundamental frequency, formant, and intensity features and mel-frequency cepstral coefficients. They were refined using principal component analysis and/or feature selection. The authors calculated an SPCIR using multiple linear regression analysis. Conclusion: In addition, this study proposes a binary discrimination model of SPCIR using multivariate logistic regression and model selection with receiver operating characteristic curve analysis and reports on the sensitivity and specificity of SPCIR for diagnosis (control vs. MCI/mAD). The study also reports discriminative performances well, thereby suggesting that the proposed approach might be an effective tool for screening the elderly for mAD and MCI.

Vaccination is the single most important preventive medicine action worldwide. However, there are inequalities in the procurement of vaccines particularly among US ethnic and racial minority males when compared to the rest of the US population. This study explored the reasons given by adult Mexican-origin males residing in Texas, for obtaining or not, immunizations. This was a cross-sectional, exploratory study with a sample of convenience of 401 adult males (age range 18–79) who were invited to participate in the study while waiting their turn to receive administrative services at the Mexican Consulate in Austin Texas. Data was collected in Spanish with a seven-item multiple choice questionnaire, using electronic tablets. The majority of respondents received their last vaccination longer than 5 years earlier. A higher percentage of individuals in the older age groups received a vaccine in the last year, as opposed to their younger counterparts who obtained their last immunization 3 to 5 years earlier. Among the reasons given for not getting vaccinated were lack of time or money, feared injections and side effects, insufficient information, interest or motivation. Others did not get vaccines because they perceived themselves to be healthy and did not feel sick. Findings from this study have important implications for future preventive medicine and vaccination practices that reach socially excluded groups in times of COVID-19. Recommendations are made to facilitate access to vaccines to the target group of this study and other socially disadvantaged populations in the global health context.
