The overall objective of OLP was to develop and test an integrated computer-based system to supplement conventional speech therapy.

More detailed objectives were, in roughly chronological order:

1. to recruit client groups and collect databases for the study;
2. to provide visual feedback mapping instantaneous acoustics onto position on a trainable, two dimensional "phonetic map";
3. to offer a range of trainable automatic speech recognition tools providing evaluative feedback to the client and an interface to speech technology;
4. to allow Objectives #2 and #3 to be tailored to the needs of a client group or an individual;
5. to provide an interface allowing this customisation to be performed easily by the therapist;
6. to make this software available for use off-site as telemedicine; and
7. to evaluate OLP with respect to clients and therapists.

For a person with a speech disorder, OLP helps create correct speech patterns, provides individualised motivating feedback and an interface to assistive technology, and allows continuation of therapy outside a clinical setting. For the speech therapist, OLP is a valuable tool supplementing speech therapy by facilitating teaching of speech patterns, providing objective client evaluations, and by allowing remote supervision of therapy thus leaving time for more patients.
