Word Error Rate (WER) for Recognition of Natural Interactions

In the INIT Lab, we focus on natural user interaction for children. Many of these modalities, such as touch, gesture, and speech, involve some type of recognition process to understand what the user input is. To determine how accurate a recognizer is, there are several methods. One of these methods […]
