Voki

Voki is a great tool that allows users to create their own speaking avatar. Introducing a speaking avatar as your teaching assistant can make your English class fun and exciting!

Here is the website of Voki:

• you can create your own speaking avatar.  
• you can create a Voki classroom where students can view and do their Voki assignment, and teachers can review students' assignments.
• you can create presentation and add speaking avatar to each slide

Here are some ways Voki can be used for students to promote better learning outcome:

• students can use Voki to record themselves reading a passage or saying dialogue, and listen to their recordings to check their pronunciation and fluency.
• students can use Voki to give presentation to the whole class in English, especially for those who feel uncomfortable speaking publicly, so other students can give comments to the presentation without the fear of embarrassing the speaker.

Voki offers a lot of useful and creative lesson plans. Here is a lesson plan I found from the website:
