The FUL ASR system examines the acoustic properties of a speech sound and extracts distinctive features from it. These features are then matched against a lexicon to identify the words used. The result is an ASR system that requires little training, and employs theoretical insights from the study of how the human brain processes speech to emulate this process
on the computer.
Based on these principles, a mobile phone language learning application was produced enabling second language learners to improve their pronunciation. Words and sentences spoken into the App are analysed, and specific feedback is given like a personal tutor to improve and correct mistakes.
