求翻译：Edison began to make a talking machine in 1877.At first he used paper with holes to make a sound.He worked for months on this idea,at last he found how to record a person's vioce.But the frist machine was very simple and the voice was only type and not clear enough.Then he spent another long time on it.He changed some parts and he put some new ones on the talking machine.This time the voice could be played and the voice was also very clear.After the Second World War others used his method to record music and songs.Then came the tape recorder.It is much easier to record voice.How great Edison was!是什么意思？
