I have used the romanization system as set up by the Guangdong Provincial Education Department in 1960. Please click here for a summary in Chinese.
This means that I will be avoiding the gallicized Hakka spellings that are commonly used in Mauritius, such as in names like 'Ah Voune' and 'Ah Youille' (although I am quite fond of them and they are a unique linguistic specimen!).
Here follows a very, very rough guide to pronouncing Hakka.
Consonants pronounced as in English:
f as in fun
h as in hand
l as in love
m as in mum
n as in no
s as in sun
v as in van
Consonants with subtle differences:
b like the unaspirated 'p' in 'spell'
p like the aspirated 'p' in 'pat'
d like the unaspirated 't' in 'stay'
t like the aspirated 't' in 'tap'
g like the unaspirated 'k' in 'skill'
k like the aspirated 'k' in 'kiss'
z like a cross between the 'dz' sound in 'adds' and the 'ts' sound in 'cats' e.g. congee 粥 zug(5)
j like z above but used only when the next letter is 'i' e.g. older sister 姊 ji(3)
c like the 'ts' sound in 'cats' e.g. car/vehicle 车 ca(1)
q like c (above) but used only when the next letter is 'i' e.g. seven 七 qid(5)
x like a cross between 's' and 'sh' e.g. small 小 xiau(3)
ng [+a or +o] like the 'ng' in 'song' e.g. I, me 𠊎 ngai(2)
ng [+i] like the 'ny' in 'can you' e.g. person 人 ngin(2)
VOWELS (British Pronunciation!)
a as in 'at' e.g. tea 茶 ca(2)
ê as in 'let' e.g. North 北 bêd(5)
e as the 'schwa' sound in 'taken' e.g. eat 食 sed(6)
i as in 'fin' e.g. gold 金 gim(1) (except in the combinations 'si' and 'zi', where the 'i' is pronounced like a longer version of the 'schwa' sound mentioned above)
o as in 'on' e.g. egg 卵 lon(3)
u like a shorter version of the 'oo' in 'too' e.g. red 红 fung(2)
