Project: Automatic assessment of reading ability of children

Acronym: LETSREAD
Main Objective:
This work aims to develop a technological module for Portuguese children, able to detect mispronunciations, hesitations and other disfluency indicators, in order to compute an overall reading ability index. The main problem consists in the detection of mispronunciations, which requires detailed acoustic models and new detection techniques dealing with speech variability using models of allowable pronunciations. The developed methods can be put to use in a prototype application, useful not only for the children, but also for the teachers and tutors that are involved in their education. The proposed system could be used in the near future in primary schools as a complimentary way of assessment of students or as a speech therapy tool.
