Snapvine.com allows you to send and receive audio messages.
You can send messages without registering, but if you want to make a profile and set up a voice player on your personal page you must then register. Moreover, the site enables you to put multiple copies of the voice player on different sites. You can put copies in all of your social networks and your blog and receive the same comments on each site. You can invite people to send you messages, by making an introduction and uploading a photo. With Snapvine.com you can also receive mobile alerts that notify you when you have received an audio message. Make comments and communication more personal by including your voice at Snapvine.com.
