No HD Voice in Lion supported

I just bought this application so i dont have to read my huge collection of ebooks. For the most part vBookz works but i am dissappointed that it doesnt support OS X Lion high defition voice. For instance when i select Speech > Voice > Tom there is no output. The HD voice is more human natural instead of Agnes/Alex robotic voice. I would update to a 5 star rating if this application is update to support new HD Voices in Lion.
