Say2go.com - Near Real-Time Voice Chat

Say2Go is a next generation instant messaging client that allows you to record voice messages and send them in text and voice formats. Instead of typing an instant message, simply press and hold the space bar and then speak your message into your microphone.

When you release the spacebar, you can listen to your message and record again if you don’t like it, or send it. The recipient receives your voice message as a converted text message and can also choose to listen to the original voice message if they desire. You can also schedule messages to be sent at a later date which is a great way of sending yourself reminders. A soon-to-be-released enhancement will also allow you to send voice messages to any regular phone and enhance your messages with background sounds.
