All three speakers are Irish and thus speak Hiberno English. What first struck me in their speech was their pronunciation of the 'r' in words like "appropriate", "irony", and "persona". Hiberno English is namely a rhotic English dialect. Second, their clear pronunciation of the 'l' in words like "cruel", "people", and "popular" also betrays their Irish nationality. Finally, the three speakers' (nearly) fricative pronunciation of the 't' in words like "about", "but", and "it" is typical for Hiberno English.
