The voice is the sound we emit when we want to communicate, either with words or with other natural human sounds, such as laughter, crying, shouting, etc. The voice plays a necessary role in people, more than it seems. For that reason, when we suffer some alteration that entails a change in its volume or timbre, we may even lose it completely. Until there is a change in our voice, we do not realize its importance. good post very enjoyable, thank you
