Yes, some words on the TTS are pronounced wrong and we're trying our best to fix this by disabling audio for sentences containing the words pronounced wrongly in the beta phase.
We are considering our options (one of which is going with recorded audio instead).
We will have to wait and see what we could to, but it the mean time, disabling wrongly pronounced audio sentences is our only option.
