Tri sounds very similar to chi. I suppose it is wrong?
(Edited - sorry, I misunderstood the question!)
Sorry, I meant the chi in english prononciation, like in church. I ve listened the word on Forvo and it sounds more like English tree, quite different from speech here.
There is something wrong with the audio and that is the emphasis, which should be on the 'Sioc' of chocolate, which would slow the audio down a little.
The Geraint, Welsh voice, on Ivona does it better.
