CHASING

Duration: -

The CHASING project investigated the potentials of web-based speech training for neurological patients. 

The CHASING project (short for: CHAllenging Speech training In Neurological patients by interactive Gaming) is an extension of the EST research program (Beijer, Rietveld et al., 2010, 2011, 2012), which investigated the potentials of web-based speech training for neurological patients. Results so far indicated that patients appreciate web-based speech training as opposed to face-to face training with a therapist, and that this training has positive effects for chronic neurological patients with dysarthric speech and diminished speech intelligibility.

Chronic patients with Parkinson’s disease and stroke tend to succeed in realizing the targeted increased voice intensity (i.e. loudness), which is required for adequate communication, but speech intelligibility lags behind. Improved articulation is believed to lead to improved speech intelligibility, but this requires further research. Since auditory speech discrimination skills in neurological patients call for augmentative feedback, patients received visual feedback on their speech, which was perceived as static and abstract.

Game development for speech training

The current results indicate the need to develop advanced, motivating training devices that provide guidance on articulation improvement and that allow the integrated benefits of intensified, independent speech training. Serious games are known to have strong motivational power, depending on the social setting (Gajadhar, 2009). To study to what extent serious games and games principles motivate and support neurological patients in speech training, an interactive, intuitive, user adaptive game for speech training that makes use of advanced speech technology and is compatible with mobile platforms was developed and tested.

This project was financed by NWO and conducted by the Centre for Language and Speech Technology (CLST) of the Radboud University Nijmegen, Sint Maartenskliniek and Waag.
