Vowels: Standard - 'u' as in 'put', 'a' as in 'path' or 'car', 'i' as in 'sit'.
Variation - 'a' followed by 'y' and another vowel is pronounced 'ai' or 'i' as in 'ice', - when 'a' follows a 'w' and is followed by an 'n' it is 'a' as in 'war'.
Consonant combination: 'th' (dental plosive) combine 't' and 'h' with tongue right against the teeth (like 'd' in 'dad'), - 'ny' (palato-nasal) combine 'n' and 'y' while top of tongue touches hard palate plus nasal vibration. (Avoid the English 'nee' as in 'many').
