In our introduction to audio processing, we spoke of various audio applications, including text-to-speech. Talkr.com offers a text to speech service for blogs. Using this service, you can now listen to any of the posts on this blog. You can also establish an RSS feed for an automatically generated podcast of the blog entries. Setting this up took only a few minutes -- one line of HTML sends the permalink for the blog entry to the Talkr.com server which generates the audio file from the text.
