I do wonder about the accuracy of the reconstructions. It seems that all of the European languages reconstructed sound suspiciously like German to me, and all of the ancient Middle Eastern languages presented sound a lot like modern Arabic to me... and the Asian languages presented appear to lack the sing-song tonality modifications present in modern Asian languages, where tone and pitch affect meaning nearly as much as the phonemes presented.
