Co-speech gestures are everywhere. People make gestures when they chat with others, give a public speech, talk on a phone, and even think aloud. Despite this ubiquity, there are not many datasets available. The main reason is that it is expensive to recruit actors/actresses and track precise body motions. There are a few datasets available (e.g., MSP AVATAR [17] and Personality Dyads Corpus [18]), but their sizes are limited to less than 3 h, and they lack diversity in speech content and speakers. The gestures also could be unnatural owing to inconvenient body tracking suits and acting in a lab environment.
