Subclaims¶

q3 i? Despite slightly greater gains for the ASR group, none of the three groups improved significantly in /y/ perception (ASR: p > 0.05; Non-ASR: p > 0.38; Control: p > 0.37). → Liakin et al. 2015

Evidence¶

Liakin et al. 2015¶

Denis Liakin, Walcir Cardoso and Natallia Liakina. (2015). Learning L2 pronunciation with a mobile speech recognizer: French /y/. CALICO Journal 32.1. https://doi.org/10.1558/cj.v32i1.25962

q3 · i? · causal · r2

Dependent samples t-tests on the four-item multiple-choice pseudoword perception task (45 pseudowords containing /y/, /u/, /i/) showed no significant pre/post gains in any group; only p-values are printed, so no effect size is reported.

"the three groups behaved in a similar way (pre/posttest differences: ASR: p > 0.05; Non-ASR: p > 0.38; Control: p > 0.37). This indicates that the group that received ASR-based treatment was not able to extend the newly acquired knowledge detected in production to perception"

Discussion¶

Learner Variables¶

• Auditory Processing — outcome: instruction changes it

Related Claims¶

• One-way ANOVAs found no differences among the ASR, Non-ASR and Control groups on pretest or posttest in either /y/ production or perception — related
• CAPT software shows promising results for segmental pronunciation, while prosodic features and fluency still require further research and development — related
