Sometimes I feel that my voice sounds as if my nostrils are blocked, and I am catching a cold. (I listen to my speaking recorded by my laptop.) It will sound better, if I pay more attention to pronounce nasal sounds. But I don't know how to consciously do that.
This is what I understand "hyponasal" intended to mean. (I haven't been able to find a recording sample of hyponasal voice on the internet yet.)
Do you have ways to improve it? I especially like to know non-surgery or non-medical way.
