The OLP (Ortho-Logo-Paedia) project aims at improving the quality of life of persons with articulatory impairments by applying a novel technological aid to speech therapy, by integrating this training with speech recognition technology and by making these facilities available over the Internet.

The OLP (Ortho-Logo-Paedia) project aims at applying a method to supplement (but not replace) speech therapy for specific disorders at the articulation level based on an integrated computer-based system together with automatic speech recognition and distance learning. The key features of the project are: (a) therapy based on real-time audio-visual feedback of client's speech; (b) speech production evaluation and interfacing to assistive technology provided through automatic speech recognition; and (c) web services to provide remote collaboration and data collection for analysis and evaluation in diverse conditions.

The OLP project is an EU Quality of Life and Management of Living Resources project, coordinated by the Institute for Language and Speech Processing, Athens, Greece, with participation from France (Arches), Greece (Altec S.A. and Logos Centre for Speech-Voice Pathology), Spain (Universidad Politécnica de Madrid), Sweden (KTH), and the UK (Sheffield University and Barnsley District General Hospital).
