Blabberize. It's free and it is quick, but it could be very beneficial in a foreign language class or even some other classes where a quick presentation could take place.
Here is how it works: You find a photo or a picture and upload it to their site. Then, you record a clip of information one of three ways, microphone, telephone or upload. Then, the site merges the audio together with the image and you have a talking photo.
I see this being very useful for a quick response in foreign language. It appears that only one person can speak so no conversations but maybe students can answer a quick question or something.
I wouldn't use this often in my classroom, maybe from time to time as a change in pace. It's definitely worth looking into.
