Finally! Tormod sounds like Tormhodh, same as in Sengoidelg. :)
I do not know what Sengoidelg means, but thank you for this. Now I know how to prinounce Tormod!
That's the Old Irish, predecessor of both Gaeilge and Gaidhlig. They lenited almost all intermediate and terminal consonants.
The 'cho' sounds like 'wus' - I find this speaker most difficult to understand.
