Create a talking avatar by using one of many avatar-making websites such as Voki.com and SitePal.com, as listed on Google's webtoolsbox. Such websites provide you with an easy-to-use avatar creator interface to help you make a personalized animated avatar.
Voki.com lets you choose from a variety of ready-made avatar characters, each having a unique design and animations. You can alter the default look of your avatar by adding different clothes and accessories to it. A variety of backdrops is available to go behind your avatar, or alternately you can upload a background image from your computer. You can then add your own voice to your avatar using your phone or a microphone or by uploading a pre-recorded sound file to the website. You can also use the site's text-to-speech feature to write out what you want your avatar to say. All of this can be done via Voki's straightforward graphical interface that takes you through this process of making an avatar step by step. When you are done creating your talking avatar, you can email it to a friend or get a code to use it on other platforms. This whole process is similar on other avatar-creating websites such as SitePal.com.
