Any good text to speech native extension for Air?

hi,

I was looking into text to speech functionality to include in my apps. Does anyone know of a decent (and up to date) native extension for air? I found this one, but don't know if it's any good (http://easynativeextensions.com/product/text-to-speech-native-extension/). Besides, it's only available for iOS and not Android.

Do any of you guys have any experience with text to speech in your apps?

thanks!
