HINTS ON PRONUNCIATION FOR FOREIGNERS

From the text:

I take it you already know [nәʊ]
Of tough and bough and cough and dough?
[tʌf] & [baʊ] & [kɒf] & [dәʊ]
Others may stumble, but not you,
On hiccough, thorough, laugh and through.
[`hıkʌp], [`θʌrә], [lɑ:f] & [θru:]
Well done! And now you wish, perhaps [pә`hæps],
To learn of less familiar traps?
