The Easi-Speak Digital Microphone/Recorder, from Learning Resources, is an easy to use wireless microphone that records and stores sound files. It can store up to 4 hours of audio and the files can be transferred to your computer via USB cable and then saved or shared.
It is very easy to use. One button to record and then simply play back and listen through the built in speaker. The battery is sealed and rechargable through the included USB cable and works with PC or Mac computers. Files are uploaded as either WAV or MP3 files and can be saved for digital portfolios, played back for practice, or shared. The built in speaker allows you to instantly play back and review recordings.
So, why would you want one of these? The Easi-Speak Digital Microphone/Recorder can be used for students who don't want to talk in front of the class, to record students practicing speech in language arts, for speech therapy, for practicing public speaking, and to record audio for projects.
It is designed for ages 4+ and up and is portable and easy to use right out of the box.
It has a cover for the USB port that is attached to the microphone by a string so it won't get lost, along with a lanyard so that it won't hit the ground if a student drops it. While it is designed for younger students, it worked well with high school students who used it to record audio for a project they did.
It could also be used by a teacher to record audio in a class for absent students to be able to listen to later.
Durable, easy to use, built-in rechargable battery, and very useful.
