Subclaims¶

q3 i? Robot-assisted SSI training improved on-focus expansion in duration and produced post-focus compression of mean f0 in autistic children's speech. → Chen 2026 q3 i? After robot-assisted training, post-focus words showed significantly lower f0 than broad focus words with a larger difference than before training. → Chen 2026 (2)

Chen 2026¶

Chen, S., Wang, B.X., Cheung, J.C.-W. et al. (2026). Lab perceptual training and robot-assisted training in improving speech prosody of autistic children. npj Science of Learning. https://doi.org/10.1038/s41539-026-00425-7

q3 · i? · causal · r?

Authors' summary of pre/post LMM post-hoc comparisons for the robot-assisted SSI training group in the randomized study; on-focus f0 and intensity expansion did not significantly improve. No effect size printed.

"the robot speech training may improve significantly in f0 in the post-focus position, on-focus expansion in using the acoustic cue of duration and it leads to some improvement in the use of intensity."

q3 · i? · causal · r?

Pre/post comparison in the robot-assisted SSI group showing post-focus f0 compression strengthened after training, described descriptively with no test statistic or effect size printed.

"post-focus words have significantly lower f0 than broad focus words in both pre- and post-training sessions, but the difference in f0 between post-focus and broad focus words is larger in post-sessions."
