ModelTalker Speech Synthesis System title

Welcome to !

We have released beta version! Visit the Project News page for important information about this minor update and how you can obtain it.

The ModelTalker System is a revolutionary speech synthesis software package designed to benefit people who are losing or who have already lost their ability to speak. It allows people with ALS or other conditions to use a synthetic version of their own voice for communication, or to choose a voice best suited to represent them.

The system uses representative segments of recorded speech (either from an individual who is losing the ability to speak or from a person chosen by someone who can no longer speak) to create a unique synthetic voice. This synthetic voice is virtually unlimited, meaning it can be used to express almost anything, including words and phrases not previously recorded. The voice "banking" process is guided by the ModelTalker Voice Recorder, our computer-assisted voice recording software (now in an experimental web-based version for non-Windows users). Once this process is finished, an individual will be able to create a synthetic voice by uploading their recordings to a voice generation site. The voice, when combined with our ModelTalker Text-to-Speech system, can then be used with any communication system that is SAPI 5.0 compatible.

Currently, the complete ModelTalker System is in the early stages of commercial development and we are actively seeking beta testers.


The ModelTalker System was developed by the Nemours Speech Research Laboratory located at the Alfred I. duPont Hospital for Children with funding from the National Institute for Disability and Rehabilitation Research, the National Institutes of Health, and Nemours Biomedical Research.
