Adding an audio message to your classroom blog or website can be a good way to help deliver important messages to your students and their parents. Having an audio message, even if it's the same as a text announcement, increases the chances that a visitor to your blog will take notice of something important. Adding an audio message to your blog or website is not difficult to do. Here are three great sites to help you incorporate audio messages into your blog or website:
Vocaroo is a free service that allows users to create audio recordings without the need to install any software. You don't even have to create an account to use Vocaroo. All you need to provide is a microphone. Vocaroo provides the embed code for you. You can also download your recording, just look for the download link at the bottom of the page (it's small and easily overlooked).
Audio Pal is a free service that allows you to quickly and easily record audio messages to post your blog or website. You can record your Audio Pal message by phone, through your computer's microphone, or by uploading a recording. Messages are limited to sixty seconds so you must be succinct. When you have a recording with which you're happy, enter your email address and an embed code will be sent to you almost immediately.
Voki for Educators is a service that allows users to create animated audio avatars that they can embed into their wikis, blogs, and websites.
