It is important to distinguish between voice, speech and language disorders: While a voice disorder is linked to the primary signal production (e.g. hoarseness, vocal fold paralysis), speech disorders accrue in the more complex process of sound production and modulation (e.g. nasality, problems articulating plosives, ...). Last, language disorders are linked to language development (e.g. the vocabulary size, grammaticality) and planning (e.g. stuttering).
In this tutorial, we give an introduction to a selection of the most common voice, speech and language disorders and their medical pathologies. We show how to cooperate with medical doctors and what technical tools can be integrated to the clinical work flow of speech therapists. With the help of data acquisition tools and therapists, means for automatic assessment can be investigated and validated in clinical trials. These automatic measures can help the therapy by providing an objective and quantitative measure of treatment success.
This tutorial is intended for speech engineers that are interested in medical speech processing and want to learn about the medical background, how to cooperate with medical doctors and how to conduct clinical trials including data acquisition, statistical analysis and privacy issues. We also show results of clinical trials on various pathologies and give a hands-on introduction to the client-server tool that was used for the whole process.
Tobias Bocklet received his diploma degree in computer science in 2007
at the University of Erlangen- Nuremberg. Together with his adviser
Elmar Nöth, he works towards his doctoral degree on medical
applications of speech and speaker recognition focusing on children
voice, speech and language development and pathologies. Since 2008,
he collaborates with the speech group of SRI International,
contributing to their NIST speaker ID evaluation system.
