This book is not about empty words and false¹ promises, rather about cooperation(合作)needed by deaf people(people who cannot hear or hear well) from those who speak to them. Any person who is willing² to give his co-operation by practising the following points will not only make conversation(谈话)easier for deaf people, but also for himself.
Please do not shout at deaf people if possible. Shouting usually distorts(扭曲)the speaker's face so as to make the listener³ feel uncomfortable and the conversation unnatural⁴. Speech is best heard when it is given in a clear voice just slightly louder than normal.
Clearness rather than loudness is often the main requirement⁵ in speaking. Many deaf people have some ability to lip-read without going to lip-reading classes. Some partly-deaf people may practice this skill without realizing it. They feel that they can hear a speaker better when he is facing them. They probably understand more exactly because what they see in the speaker's expressions⁶ and lip-movements also help them understand what they only partly hear.
