Mobento is a new site that lets you search for words spoken in videos. For now, they have indexed ones from Khan, TED and Stanford, and plan a lot more.
It’s pretty straightforward — you type a word into the searchbox, and it shows you the videos where it has appeared. click on the video, and under the screen there’s a mark where the word is spoken. Click on each mark, and you hear it and its context.
It could be useful, especially as they expand their collection.
You can search the videos without registering, but have to sign-up if you want to leave a comment.
Thanks to TechCrunch for the tip.
Pretty nice and the best yet out of the bunch of sites trying to do this. However, still cumbersome and too academic for language learning.
We’ve built something far superior on EnglishCentral. Even speak the lines (for free) and get precise definitions and many, many usages. We call them clip lists. You’ll see a small number on the thumbnail of any word/expression/idiom. Go to http://www.englishcentral.com/vocabulary This gives you all our “corpus” but select from categories on the right or use our search (and select under “Word”). When you click a thumbnail, students and teachers get multiple examples along with the transcript.
I’ve been working hard to build some vocabulary courses (students can study specific vocabulary by theme or the GSL / AWL) which use these clip lists for student study. We’ll release the first of them later this week.
