“…How this is best accomplished within the field of communication sciences and disorders has recently been addressed in a tutorial by Douglas and Burshnic (2019). Identifying children in need for SLP assessment and/or intervention could be aided by using the quick ICS screening tool, in study II shown to be reliable for rating a child's intelligibility (for more information about the ICS validity and reliability, see McLeod, 2020). Children born with CP±L are enrolled in a cleft palate team in Sweden, with scheduled routine visits to a SLP at ages 1.5, 3, 5, 7, 10, 16 and 19 years.…”

“…As regards validity, this was examined by comparing the ICS score with the GS (i.e., congruent validity) intelligibility measure based on listener transcripts of video-recorded samples of spontaneous speech. Other studies that have validated ICS have often used articulation (PCC) to investigate the strength of correlation with ICS scores, that is, criterion validity (McLeod, 2020). However, since the PCC is a measure of articulation rather than of intelligibility, the connections are often found to be rather weak.…”

Background: Intelligibility can be defined as the speakers' ability to convey a message to the listener and it is considered the key functional measure of speech. The Intelligibility in Context Scale (ICS) is a parent rating scale used to assess intelligibility in children. Aims: To describe normative and validation data on the ICS in Swedish and to investigate how these are related to age, gender and multilingualism. Methods & Procedures: Two studies were included. Study 1 included ICS forms from 319 Swedish-speaking children (3:2-9:2 years:months). Study 2 included video recordings and ICS forms from 14 children with speech sound disorder (SSD) and two with typical speech. The video recordings were transcribed in the validation process, resulting in intelligibility reference scores to which ICS scores were correlated.Outcomes & Results: Study 1: The mean value of the ICS for the 319 children was 4.73. There were no differences in ICS score related to age or gender. The children in the multilingual group were significantly older than the monolingual group and had significantly lower ICS scores than the group of monolinguals. Study 2: There was a moderate correlation between the ICS score and the transcription-based intelligibility score, with the two children with typical speech excluded; however, this correlation was not significant. Conclusions & Implications:We contribute mean scores and percentiles on the ICS for Swedish-speaking children. The finding that the ICS does not provide valid measures of intelligibility for the included children with SSD suggests that the instrument measures a different construct.This is an open access article under the terms of the Creative Commons Attribution-NonCommercial-NoDerivs License, which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made.

“…The VSA was designed so that the vocabulary and pronunciation of words was equally appropriate for children from Southern, Central and Northern Viet Nam and consideration was also made for the Vietnamese diaspora in countries such as Australia and the USA. The VSA was used with 195 children who speak Northern Vietnamese (Phạm & McLeod, 2019) and is currently being used in a study of bilingual Vietnamese-English speaking children in Australia (McLeod & Verdon, 2018-2020McLeod et al, 2021).…”

Understanding typically developing children's speech acquisition is useful to assist speechlanguage pathologists' diagnosis and intervention planning for children with speech sound disorders. The aim of this research was to investigate Southern Vietnamese-speaking children's speech accuracy and intelligibility. Participants were 132 children aged 3;0-5;11 living in Southern Viet Nam (Ho Chi Minh City) whose consonants, semivowels, vowels, and tones were assessed using the Vietnamese Speech Assessment (VSA) and parent-reported intelligibility was assessed using the Vietnamese version of the Intelligibility in Context Scale (ICS-VN). Participants' percentage of consonants correct (PCC) was significantly lower for the younger children compared with the other age groups. Mean PCC was 89.19 (SD = 7.83) at 3;0-3;5 years and 99.31 (SD = 1.33) at 5;6-5;11 years. Percentage of semivowels correct was higher than the percentage of initial and final consonants correct. Participants produced tones and vowels accurately even from the youngest age group. On average, the participants were reported to be usually to always intelligible and were more intelligible with their parents than other communication partners. There was a positive, weak correlation between speech accuracy (PCC) and intelligibility (ICS-VN). There was no sex effect for PCC and no significant effect for age or sex on intelligibility. These data provide information about typical speech acquisition to support the emerging speech-language pathology profession in Viet Nam.

Intelligibility in Context Scale: cross-linguistic use, validity, and reliability

Abstract: The Intelligibility in Context Scale (ICS) is a free parent-report screening tool that has been translated into over 60 languages. To date, there is cross-linguistic evidence regarding its validity and reliability reported in 18 studies of over 4235 children from 14 countries (Australia,
