Protocol for the Connected Speech Transcription of Children with Speech Disorders: An Example from Childhood Apraxia of Speech.
Catherine Barrett, Patricia McCabe, Sarah Masso and 1 others
PMID 31269497WHAT IT FOUND
A connected speech transcription protocol documented inter-word pauses and linking sounds in children with childhood apraxia of speech, but transcribing 50 utterances took 5 to 7 hours per child.
It is not yet a routine clinical tool.
Key findings
01Overall protocol fidelity was 88%, but fidelity for transcribing utterances as connected speech strings was 55%.
02Transcribing 50 utterances into the three tiers took researchers between 5 and 7 hours.
03In the relational analysis, connected speech string accuracy was 35% and juncture accuracy was 54%.

What it does not show
Only 12 children were studied, and relational analysis was possible for 10 because two samples were too unintelligible. The children were a convenience sample from one area and all used a non-rhotic English dialect, so the protocol was not tested across dialects or languages. The speech samples were spontaneous, so some sounds and word shapes may not have appeared. Full transcription took 5 to 7 hours per child, so it is not practical for routine clinical use. Fidelity for the central idea of transcribing speech as connected strings was 55%, and raters differed on glottal stops versus pauses. The study did not compare children with typically developing speech, did not create norms, and did not test whether the protocol improves diagnosis or therapy.
The easy way to misread this
Do not conclude that the CoST-P is ready for routine clinical use. It took 5 to 7 hours per child, fidelity for speech strings was 55%, and the study did not test whether it improves diagnosis or therapy.
