Item English (Scottish) speech development(Oxford University Press, 2024) Scobbie, James M.; Cleland, Joanne; Lawson, Eleanor; Schaeffler, Sonja; McLeod, SharynneScottish English is primarily spoken in Scotland, U.K. It is a national quasi-standard variety of English with a range of social and geographical variants. It can be characterized as a highly distinctive accent (or accent group) of English, mainly due to its relationship to Scots. Its strongly distinct character may be more phonetic, prosodic and lexical than strictly phonemic and phonological, so for practical reasons it can be assumed that its inventory and consonant phonotactics overlap sufficiently with other varieties for many “British English” clinical resources to be applicable. Scottish English is, however, rhotic in its prestige varieties, which makes it markedly different from non-rhotic Southern Standard British English and other non-rhotic varieties. There are few specific studies of children’s acquisition of Scottish English, though Scottish children are often incorporated in larger studies in the U.K. Research on Scottish English has focused on social variation, speech production, and remediation techniques augmented with real time visual biofeedback, involving children with speech sound disorders and cleft palate. Commonly-used speech assessments and interventions have not been developed specifically for this variety of English.Item The impact of real-time articulatory information on phonetic transcription: Ultrasound-aided transcription in cleft lip and palate speech(Karger, 2019-05-24) Cleland, Joanne; Lloyd, Susan; Campbell, Linsay; Crampin, Lisa; Palo, Pertti; Sugden, Eleanor; Wrench, Alan A.; Zharkova, NataliaObjective: This study investigated whether adding an additional modality, namely ultrasound tongue imaging, to perception-based phonetic transcription impacted on the identification of compensatory articulations and on interrater reliability. Patients and Methods: Thirty-nine English-speaking children aged 3 to 12 with cleft lip and palate (CLP) were recorded producing repetitions of /aCa/ for all places of articulation with simultaneous audio and probe-stabilised ultrasound. Three types of transcriptions were performed: 1. Descriptive observations from the live ultrasound by the clinician recording the data; 2. Ultrasound-aided transcription by two ultrasound-trained clinicians; and 3. Traditional phonetic transcription by two CLP specialists from audio recording. We compared the number of consonants identified as in error by each transcriber and then classified errors into eight different subcategories. Results: Both the ultrasound-aided and traditional transcriptions yielded similar error-detection rates, however these were significantly higher than the observations recorded live in the clinic. Interrater reliability for the ultrasound transcribers was substantial (k=0.65), compared to moderate (k=0.47) for the traditional transcribers. Ultrasound-aided transcribers were more likely to identify covert errors such as double articulations and retroflexion than the audio-only transcribers. Conclusion: Ultrasound-tongue imaging is a useful complement to traditional phonetic transcription for CLP speech.
