Voki

Voki is a similar platform to Flipgrid but it's more interesting one. It also aims to develop students' speaking skills as Flipgrid does but main difference is that Voki provides avatars and animations. Voki makes students feel more comfortable since they don't need to use their own voices and videos. It suggests an easy way to make speech practices. In my opinion, Voki makes the lesson more enjoyable and it offers different experience.
