Windows store apps SDK doesnt support System.Speech class. Thus we can’t use Text to speech in windows store apps we develop. Though Bing translator API supports this, that is not capable of rendering some complex words. Google has a translator API which can perform TTS work as well. For sample in your browser type this url http://translate.google.com/translate_tts?tl=en&q=I%20hope%20this%20helps%20you%20get%20started.%20Of%20course,%20there%20are%20many%20better%20approaches%20to%20this.
