Vocaro is a great voice recording service. It allows you to easily and instantly record your voice and share it with others. What I really liked about Vocaro is its simplicity and user friendliness. Most of the voice recording systems are complicated and hard to use and that is why teachers shun away from them. Vocaro offers a different experience. It has an intuitive interface and is free to use.
To start using Vocaro , just head over to their main page and start recording your voice but it is better if you sign up up and have your account there.
