It should sound like "Pet-ree-al", and the one I'm hearing is missing the "ee" sound.

The problem for the voice synthesiser is that it doesn't know if the 'y' is a short or a long vowel and it's guessed wrong so that the pronunciation of the word is wrong.

To hear it correctly pronounced go to ivona.com, choose one of the Welsh voices and get it to say :- petrŷal
