“…We chose to investigate CLP speech as it is particularly vulnerable to problems with interrater reliability due to covert errors and non-native phonetic realisations, and because it has been previously studied with a similar instrumental technique, namely electropalatography. In line with Klintö and Lohmander [16] adding an extra modality, in our case ultrasound, had little impact on the percentage of consonants recorded as correct. Both the audio-only (AO) and ultrasound-aided (UA) transcribers noted similar rates of both correct and in-error productions suggesting that both methods are valid for making decisions about overall severity of SSD or potentially for measuring outcomes after intervention.…”

“…Accuracy of these transcriptions can be improved in several ways: audio and/or video recording the speech samples for careful and repeated listening; use of listeners familiar with the client group; use of multiple transcribers [15]; acoustic analysis; or instrumental articulatory techniques. A recent study by Klintö and Lohmander [16] showed that using of video-recordings of the face, rather than audio-recording only, improved intertranscriber reliability and resulted in identification of more errors in three-year-olds with CLP.…”

Objective: 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.

“…The assumption was that this indicator would have a better interjudge percentage agreement if we used all 59 target consonants from SVANTE, 6 (10.2%) of which are /s/. The use of audio-video recordings for the ratings may also improve the agreement (Klintö and Lohmander, 2017). Calculations with κ showed better agreement than the point-by-point agreement.…”

“…In Sweden, routine visits to the CLP team SLPs are audio-recorded for clinical purposes, and video recordings are not made on a regular basis. This probably led to lower interjudge percentage agreement for PCC than audio-video recordings would have produced (Klintö and Lohmander, 2017). Thus, it might have also influenced the reliability for the quality indicator proportion of children with ≥86% correct consonants .…”

Objective: To assess the reliability of speech variables and speech-related quality indicators in the Swedish quality registry for cleft lip and palate (CLP). Design: Retrospective study. Setting: Primary care university hospitals. Participants: Fifty-two 5-year-old children with unilateral CLP and 41 with bilateral CLP. Main Outcome Measures: Registry data for “percent nonoral errors” and “perceived velopharyngeal competence” (VPC) were compared to reassessments by 4 independent judges based on audio recordings. Interjudge agreement for “percent consonants correct” (PCC) and the reliability of 3 quality indicators were also assessed. Agreement was calculated with single measures intraclass correlation coefficient (ICC) for articulation outcomes, quadratic weighted κ and ICC for VPC, and percentage agreement and κ for quality indicators. Results: When the agreement between registry data and the judges’ reassessments was assessed, the ICC was 0.79 for percent nonoral errors. For VPC, the κ coefficient was 0.66 to 0.75 and the ICC was 0.73. Interjudge agreement for PCC calculated with ICC was 0.85. For the quality indicator “proportion of children with ≥86% correct consonants,” all 4 judges were in agreement for 72% of the cases. For “proportion of children without nonoral speech errors” and “proportion of children with competent or marginally incompetent velopharyngeal function,” the agreement between registry data and the 4 judges was 89% and 85%, respectively. Conclusions: The results indicate that registry data on PCC, percent nonoral errors, VPC, and the quality indicators “proportion of children without nonoral speech errors” and “proportion of children with competent or marginally incompetent velopharyngeal function” are reliable.

“…Reliability can be improved through definitions of perceptual terms (Keuning et al, 1999), anchor stimuli (Eadie & Kapsner-Smith, 2011;Shrivastav, Sapienza, & Nandur, 2005), reference voices (Granqvist, 2003), standardization of the speech material (Klintö, Salameh, Svensson, & Lohmander, 2011), and recording medium (Klintö & Lohmander, 2017). Thus, methodological knowledge and skills training are crucial for reliable perceptual assessments.…”

Perceptual assessment is the basis for diagnosis and evaluation of treatment in speech-language pathology (SLP). Students need to practise assessment skills. A web-based platform with cases and expert feedback in cleft palate disorders was developed in national collaboration. The aim of the study was to evaluate the results of individual training on assessment skills in SLP students and their perception of e-learning. Forty-five students performed tests using a pre-and post-test setup. Perceptual assessments were demonstrated and instructions provided during teacher-led activities in ongoing fully scheduled courses; students were then individually trained in their free time. Reference samples were available. A significant improvement was found in rating and phonetic transcriptions after training. Positive comments concerned accessibility and practice time.
