Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? The speechreading training group improved significantly from pre- to post-training in the audiovisual condition, as shown by a significant three-way interaction between condition, session, and group (ΔΧ2(4) = 13.62, p = 0.009). → Raffael Schmitt 2023
q3 i? The improvement was present only in the speechreading training group and only for the audiovisual condition, not the audio-only condition. → Raffael Schmitt 2023
q3 i? The speechreading training and active control groups did not differ significantly at pre-training in the audiovisual condition (OR = 0.75, 95% CI [0.45, 1.25], p = 0.271), which the authors read as suggesting baseline differences did not confound the training effect; a non-significant test does not show the non-randomised groups were equivalent. → Raffael Schmitt 2023 (2)
Evidence¶
Raffael Schmitt 2023¶
Raffael Schmitt, Martin Meyer and Nathalie Giroud. (2023). Improvements in naturalistic speech-in-noise comprehension in middle-aged and older adults after 3 weeks of computer-based speechreading training. npj Science of Learning 8:32. https://doi.org/10.1038/s41539-023-00179-6
q3 · i? · causal · r1
GLMM analysis of single-trial data from 32 speechreading-training and 30 active-control participants on a naturalistic speech-in-noise task. The article reports "a signi ficant training effect" with the ST group improving in the AV condition, supported by the three-way interaction ΔΧ2(4) = 13.62, p = 0.009 (condition [AV]:session [post]:group [ST] OR = 1.07, p = 0.047).
"Using generalized linear mixed-effects models (GLMMs) on single-trial data, we found a signi ficant training effect, with the ST group improving signi ficantly from pre- to post-training in the audiovisual (AV) condition."

q3 · i? · causal · r1
Supplementary GLMM re-run with treatment coding comparing speechreading training and active control groups at pre-training in the audiovisual condition. The groups "did not signi ficantly differ at pre-training" (OR = 0.75, 95% CI[0.45, 1.25], p = 0.271). The authors take this as suggesting baseline differences did not confound the effect; it shows no significant difference was detected, not that the groups, which were not randomly assigned, were equivalent.
"Indeed, the two groups did not signi ficantly differ at pre-training (OR = 0.75, 95% CI[0.45, 1.25], p = 0.271) (Fig. 5 and Supplementary Table 3) suggesting that baseline differences in AV did not pose a potentially confounding factor."
Discussion¶
Learner Variables¶
- Auditory Processing — outcome: instruction changes it
Related Claims¶
- Participants who improved on audiovisual speech-in-noise comprehension had significantly lower pre-training scores than non-learners, reflecting the inherent correlation between baseline and change scores — related
- Lexical overlap between speechreading training material and test sentences did not significantly account for the observed training effect — a narrower finding that bears on this claim
- Speechreading training does not significantly improve subjectively perceived everyday listening effort or hearing abilities — related
- Visual enhancement is not significantly associated with hearing level, age, visual working memory or processing speed, and learning rate in speechreading training is not significantly associated with those or with hearing aid use or training intensity — related
- Older adults show larger multisensory gains for simple stimuli but multisensory deficits for complex speech stimuli — related
- Speech-in-noise perception improves significantly after a short-term immersive auditory-cognitive training, but not after an audio-only training session — related
