No, it's another minor audio glitch. It should be /pys-gOT-a/ with emphasis in the last but one syllable, as usual, and a short final syllable. A slight rise in tone towards the end of the sentence as it is a question.
Go to www.ivona.com and get 'Welsh, Gwyneth' or 'Welsh Geraint' to say Dych chi'n hoffi pysgota neu beidio? and it sounds much more normal - they both seem to over-do the rising tone at the end of the original sentence for some reason.
Nothing that we can do as a team except turn the sound off, which would not be very helpful overall.
