Such evaluation requires large data availability, large-scale experiments and consideration of different evaluation measures. Such constraints make the construction of ad-hoc Intelligent Tutoring Systems (ITS) unfeasible and impose early integration in already existing…

Evaluating the performance of automatic speech recognition systems

iTalk2Learn partners, Sail, explain how they evaluate automatic speech recognition systems Word Error Rate The standard measurement to assess the performance of an automatic speech recognition (ASR) system is the so-called word-error-rate (WER, (Jelinek, 1997)). WER is a minimum edit-distance measure produced by applying a dynamic alignment between the output of the ASR system and…
