You have written a great Adhearsion application and now you want to add some fancy Speech Synthesis or Speech Recognition. Your best option has been to acquire software to install on your Asterisk server. While there are open source applications available, such as Festival and Sphinx, they take a fair amount of know-how and work to tune, and then still may not perform as you hope. There are also some great commercial applications out there such as Cepstral and Lumenvox, but they require an upfront investment and add additional overhead to your Asterisk server. What if you could just obtain these services from the cloud and pay as you go?
