Okay, that would be great.
As for google translate, haha I like how you claim it sound good without knowing Arabic (it is impossible to evaluate any language you don't understand, right?). But yeah, you are correct, it is somehow good (especially when you know it is relatively new). But the loquendo implementation is far better. It almost sound like a real person is talking (even when compared to English engines that already existed for decades). They have a text to speech version for individuals, but it doesn't work with the system TTS engine.
What is good with Google is their Arabic Speech Recognition used in mobile phones. I managed to get hold of the API (even though not published), and was able to convert what I say in Arabic to text. The output was relatively good for a recent release. The only problem is that there is a delay due to the HTTP request/response and the need to encode in FLAC. Also, you have to send the audio file in chunks if it is too big. This will break the experience for real time application, or when there is no internet connection. It would be great if they released it for one of the operating systems out there, but I am not holding my breaths.
