Subclaims¶

q2 i? The three allomorphs behaved significantly differently, with -id unproblematic, -d easier to produce than -t, and a significant Time × allomorphy interaction showing improvement for -d but not -t. → Cardoso 2018

Evidence¶

Cardoso 2018¶

Cardoso, W. (2018). Learning L2 pronunciation with a text-to-speech synthesizer. In P. Taalas, J. Jalkanen, L. Bradley & S. Thouësny (Eds), Future-proof CALL: language learning as exploration and encounters – short papers from EUROCALL 2018. Research-publishing.net. https://doi.org/10.14705/rpnet.2018.26.806

q2 · i? · causal · r1

Follow-up within-subjects ANOVA on the Guided Task with the two groups combined, after the groups proved statistically similar. The article reports an interaction "between Time and RTP allomorphy" with F(1,17)=15.609, p=0.001, improvement for -d only.

"This revealed an interaction between Time and RTP allomorphy ( F(1,17)=15.609, p=0.001 (alpha level set at .003), suggesting a performance improvement for -d (shaded in Table 1), but not for -t on the posttest."

• TTS-based instruction and teacher-led instruction produce similar RPT production outcomes in EFL learners — reports the opposite
• TTS-group learners reported becoming aware of differences in RPT pronunciation in post-study interviews — related
