I have always pronounced as "dė", regardless of the context, but I have heard people pronouncing it as "di"(fifth tone). For instance,

  • 我的(di)姑娘
  • 暖暖的(di)
  • 漫長的(di)歲月

I do not remember the context of the above examples though.

Is this pronunciation applied in certain colloquial context? Or does it belong to a regional dialect?

Thanks in advance!
