Purpose We sought to critically analyze and evaluate published evidence regarding feasibility and clinical potential for predicting neurodevelopmental outcomes of the frequency-following responses (FFRs) to speech recordings in neonates (birth to 28 days). Method A systematic search of MeSH terms in the Cumulative Index to Nursing and Allied HealthLiterature, Embase, Google Scholar, Ovid Medline (R) and E-Pub Ahead of Print, In-Process & Other Non-Indexed Citations and Daily, Web of Science, SCOPUS, COCHRANE Library, and ClinicalTrials.gov was performed. Manual review of all items identified in the search was performed by two independent reviewers. Articles were evaluated based on the level of methodological quality and evidence according to the RTI item bank. Results Seven articles met inclusion criteria. None of the included studies reported neurodevelopmental outcomes past 3 months of age. Quality of the evidence ranged from moderate to high. Protocol variations were frequent. Conclusions Based on this systematic review, the FFR to speech can capture both temporal and spectral acoustic features in neonates. It can accurately be recorded in a fast and easy manner at the infant's bedside. However, at this time, further studies are needed to identify and validate which FFR features could be incorporated as an addition to standard evaluation of infant sound processing evaluation in subcortico-cortical networks. This review identifies the need for further research focused on identifying specific features of the neonatal FFRs, those with predictive value for early childhood outcomes to help guide targeted early speech and hearing interventions.

The article discusses unprepared reading in a non-native language and shows it to have all the signs of spontaneity that are traditionally considered integral characteristics of any spontaneous speech: hesitation pauses, both physical (ɭ) and filled with non-speech sounds (uh, m-m), word breaks, reading the whole word or part of it by syllables, vocalization of a consonant, and so forth. The material for the analysis included 40 monologues of reading the story by M. Zoshchenko Fantasy Shirt and a non-plot excerpt from V. Korolenko’s story The Blind Musician recorded from 20 Chinese informants. All the monologues are included in the block of Russian interfering speech of the Chinese as part of the monologic speech corpus Ba­lanced Annotated Text Library. As the analysis showed, it is more often that there is not one sign of spontaneity but a whole complex of such signs, and together they fill hesitation pauses, help the speaker to control the quality of speech or correct what was said, etc. In addition, the occurrence of various signs of spontaneity in the course of unprepared reading is closely related to the individual characteristics of the speaker/reader. In general, we have found that there are more signs of spontaneity in the speech of men (3,244 cases; 40.7 %) than in the speech of women (2,049; 27.7 %), in the speech of informants with a lower level of proficiency in Russian B2 (2,993; 37.9 %) than in the speech of informants with a higher level C1 (2,300; 30.8 %), in the speech of extroverts (1,521; 38 %) than in the speech of ambiverts (1,694; 35,2 %) and introverts (2,078; 31,7 %). As to the type of the source text, there turned out to be more signs of spontaneity in monologues of reading a plot text than in monologues of reading a non-plot text (3,031; 40.3 vs 2,283; 31 %). The paper concludes that reading should be recognized as a spontaneous type of speech activity.

This article is concerned with a study of pronunciation errors made by students of English Literature Department, Faculty of Cultural Sciences, University of Sumatera Utara. The scope is limited to the study of error analysis in the pronunciation of English phonemes. The participants of this study were two students of the department with Acehnese background. In this study, the electronic software called Praat was used as an instrument in the analysis of speech sounds of the participants. The purpose of this study was to find out the dominant errors of the pronunciation of English phonemes made by the participants. The data were derived from the pronunciations of English phonemes which were recorded and transcribed in the International Phonetic Alphabet (IPA) as in Katamba (1996: 13). The standard value of the pronunciation of English phonemes was adopted from Cambridge Advanced Learner’s Dictionary. The quality of the pronunciations of the participants was described in graphs and the results were shown in percentage as given in tables and charts.

Introduction. Phonetic and phonological system of the healthy members of one linguistic community is fully formed around 8 years of age. The auditory and articulatory habits are established with age and tend to be more difficult to be upgraded and completed later. Material and Methods. The research was done as a cross-sectional study, conducted at the preschool institution ?Radosno detinjstvo? and primary school ?Branko Radicevic? in Novi Sad. It included 66 children of both genders, aged 6 to 8. The quality of articulation was determined according to the Global Articulation Test by working with each child individually. Results. In each individual vowel, plosive, nasal, lateral and fricative, the quality of articulation was statistically significantly better in the first graders compared to the preschool children (p<0.01). In each affricate, except for the sound /c/, the quality of articulation was statistically significantly better in the first graders than in the preschool children (p<0.01). The quality of articulation of all speech sounds was statistically significantly better in the first graders than in the preschool children (p<0.01). Discussion and Conclusion. The most common disorder of articulation is distortion, while only substitution and substitution associated with distortion are less common. Omission does not occur in children from 6 to 8 years of age. Girls have slightly better quality of articulation. The articulatory disorders are more common in preschool children than in children who are in the first grade of primary school. The most commonly mispronounced sounds belong to the group of affricates and fricatives.
