Re: what is voiced speech ?!

This is the technic of analyzing the speech.
This is accomplished by dividing a speech signal of your choice into short frames and by computing the average power of each frame. The speech in a particular frame is then declared to be voiced if its average power exceeds a threshold level that is chosen by the user. Otherwise it is declared unvoiced.

Another definition is if the sound is made by the vocal cords or by air being forced through the mouth cavity with the tongue and lips shaped to accent a tone range.

You cannot make this distinction. The word "why" has vocal chord sounds on the w. The word "word" has vocal chord sounds on the r.
