Emotional Communication Assist Interface App for People with Dysarthria

Text to speech (TTS) helps people who have speech disorders communicate with other people. The current TTS can express emotion, but this requires extra time and effort. We developed a TTS application by which users can render messages with emotion with ease by changing the pitch angle of a smartphone. We designed two types of TTS: free input and phrase selection. Also, we calculated the TTS editing parameters for each degree of emotion on the basis of the Online Game Voice Chat Corpus (OGVC).
