录音笔最低能录多少分贝,人说话声音低时能不能录到

ec piay同时启动

说口语时不要不带一点感情的说,像念书一样,像说：Dear me !就要用很惊讶的口气来说.
1.可以多找一些有录音的文章读,对照着录音在书上用铅笔画调调,我们老师是用流线画,我是用汉语4声调来标的
2.标完后按调读熟,录下来和原磁带对比（最开始一定要按磁带的调读,因为还不知道怎么读调,读的文章多了自然就形成自己的调了）
3.如果有精力就对每句的调分析一下（比如可以发现：数字,人名一般都会重读,还有比如副词在什么时候不重读,介词什么时候重读.）如果你有精力大量读文章的话,这个也可以不做,会很自然的知道怎么读
这项练习最开始会有些困难,特别对于耳力不太好的人来说,因为汉语的4声是固定的,但是英语不是固定的,每一句话不同的人不同的情感调都可能不一样,开始时最好身边有学音乐的,耳力较好的人指点,时间久了就能听出来了
不建议看电影学调,因为是他们的母语,英美人都不会去深究调什么的,当他们说很长一段话的时候你会发现都是平平的,没有什么起伏,最好能跟播音员学
另外英式美式最好专学一种~

Dear Sir or Madam,
I am writing to tell you something about the recording pen . I bought it from your website several days ago .However , there seems to be something wrong with it .First , the voice isn’t so clear as you claimed .Second ,it’s not easy to operate , which has caused me much trouble .What I expect is a human –friendly one. Third , it often breaks down , while a recording pen at such a price shouldn’t have had so many problems.
Due to its poor quality and much inconvenience it has caused, I wonder whether you can do something about it .I would appreciate it very much if I can get my money back . I’ll send it back to you as soon as you return the money to me. If it can’t be helped, I wish you could have it repaired or changed.
I’m looking forward to your early reply .
Best wishes,
Yours,
Li Hua
