Lilliputing (a great little tech website) is reporting that Amazon has purchased Ivona Software, which specializes in text to speech software. Currently it offers 44 voices in 17 different languages.
I am surprised that Amazon is expanding its reaching into text to speech after it removed the feature from its e-ink kindles. The newest Kindle Fires have text to speech (but the first generation Kindle Fire did not.)
Amazon has said it will continue to support e-ink kindles, but I do get concerned when all of their development seems to be in the tablet market.
