Learning to sing is easier in a quire than alone. So apart from improving Karaoke with a quire option. I was wondering if children could learn to read by reading along with many other children.
It could work a bit like karaoke. You have many children reading the text aloud in a quire that is prerecorded in the video.
These texts of stories could perhaps be put on youtube.
Karaoke with a microphone could perhaps work for adults also. Be it reading a book or why not practice reading a speech.
So here you have many ideas. Speech Karaoke, Children book Karaoke, Poem Karaoke and Quire Karaoke.
