Simicry - A mimicry-feedback loop for second language learning

This paper introduces the concept of Simicry, defined as similarity of mimicry, for the purpose of second language acquisition. We apply this method using a computer assisted language learning system called Ville on foreign students learning Swedish. The system deploys acoustic similarity measures between native and non-native pronunciation, derived from duration syllabicity and pitch. The system uses these measures to give pronunciation feedback in a mimicry-feedback loop exercise which has two variants: a ’say after me’ mimicry exercise, and a ’shadow with me’ exercise. The answers of questionnaires filled out by students after several training sessions spread over a month, show that the learning and practicing procedure has a promising potential being very useful and fun.
