Evaluating the Recognition Performance of the RehaLingo Speech Training System with Aphasic Speech

Abstract:
RehaLingo is a speech training system designed for individuals with aphasia. Different versions of RehaLingo were tested and employed at a therapy center to support the speech therapy of patients. The system simultaneously utilizes multiple speech recognition frameworks to analyze user input. Speech data were recorded during therapy sessions. This paper focuses on evaluating the performance of the recognition systems with regard to typical aphasic speech artifacts.
