іSpeak is a translator and speech synthesis software packaged into one easy to use iOS application. Type (or copy and paste if you wish) a phrase in your native language and get the phrase BING-translated into English and spoken back to you. Hit "+" to save to your phrase book to replay later to your friends or better yet native speakers. Have fun with it. Thanks to your iDevice it is now easy to speak English.
Unlike other speech synthesis/translator applications in the app store that translate from English, iSpeak English translates from your mother tongue to English and now you could speak English too.
Finally, if you are adventurous enough to change your iDevice language settings… well, you know already then where we are going with this, right? Have fun.
