Implementation and Test of a Serious Game Based on Minimal Pairs for Pronunciation Training

SLaTE 2015, Leipzig. Workshop on Speech and Language Technology in Education. September 2015.

David Escudero-Mancebo, Enrique Cámara-Arenas, Cristian Tejedor-García, César González-Ferreras and Valentín Cardeñoso-Payo.

This paper introduces the architecture and interface of a serious game intended for pronunciation training and assessment for Spanish students of English as second language. Users will confront a challenge consisting in the pronunciation of a minimal-pair word battery. Android ASR and TTS tools will prove useful in discerning three different pronunciation proficiency levels, ranging from basic to native. Results also provide evidence of the weaknesses and limitations of present-day technologies. These must be taken into account when defining game dynamics for pedagogical purposes.

Playing around Minimal Pairs to improve pronunciation training

IFCASL Project 2015. Individualized Feedback for Computer-Assisted Spoken Language Learning. Workshop on "Feedback in Pronunciation Training". November 2015.

Cristian Tejedor-García, Valentín Cardeñoso-Payo, Enrique Cámara-Arenas, César González-Ferreras and David Escudero-Mancebo.

Computer Assisted Pronunciation Training (CAPT) apps are becoming widespread to aid learning new languages. However, they are still highly criticized for the lack of the unreplaceable need of direct feedback from a human expert. The combination of the right learning methodology with a gamification design strategy can, nevertheless, increase engagement and provide adequate feedback while keeping users active and comfortable.
