A sonorant consonant such as [ng] is made from formants, in the same
way as a vowel.

According to the wikipedia article "Standard_cantonese", there are 7
vowels which can be followed by [ng].  You could make a separate
"diphthong" for each of these:
  [ang]  [aang]  [eng]  [ing]  [ong]  [ung]  [oeng]

Perhaps that will give the best results.

I don't know what is the correct sound for [t] and [d]in Cantonese.
Currently eSpeak uses the same sound as English [t] and [d] and I hear
a big difference between these two.

Try [t] and [d] sounds from other languages to hear whether any are
better.  For example comparing English and Spanish:
  espeak -ven "[[t@]]"
  espeak -ves "[[t@]]"

  espeak -ven "[[d@]]"
  espeak -ves "[[d@]]"
