20.One of the most important components of public speaking is the sound of your voice.It influences the impact of your message,and might even make or break the success of your speech.Fortunately,for many people,good voice quality can be learned.The voice is made up of muscles,cavities,tissues,nerves,fluids,etc.,just like the rest of you.It can produce at least 325different pitches(音高).In addition,you use three quarters of your body when you speak a word.
Many things determine whether someone has a quiet voice or a loud one.Physical factors include the size of the person's upper airways and vocal cords (聲帶),the amount of breath support the speaker provides from the diaphragm(膈膜),and the size of the speaker's lungs.Other factors,such as the pitch of the voice,influence how well it can be heard,particularly in a crowd.
Personality is at work here,too.People who are not very assertive,or who are fearful in social situations,can find they speak more quietly than they wish to.In this case,since one is always told to speak up,he may be anxious when he speaks,which may cause him to become even quieter out of fear or anxiety.
But the problem can be fixed.Vocal coaches can work with people to improve their voices,giving them techniques to improve breath control,diaphragm support,and pitch..
If"shyness"is the problem,then it might be helpful to take a"social skills"class to learn how to overcome some of it.The problem of speaking too quietly may disappear with greater confidence.
Doing part-time theater can also help.Some actors report that they are basically shy people,and that acting helps them overcome their anxiety.Acting coaches work with people to help them overcome their shyness,and often are expert at helping people be heard loudly even at the back of theaters.
