Mandarin 3rd Tone

Any students or speakers here who can weigh in on this?

I've heard in several recordings native or presumably native speakers pronouncing third tones with kind of a skip in the middle—it comes out almost disyllabic—when pronounced fully at the end of an utterance, and I would like to know what is up with that. Not sure I've ever heard a male speaker do it.

I'm talking about recordings of actual speech. It will sound almost like "he1 nai3 a". Maybe that's what I'm hearing and the last word just didn't make it into the transcription.
