play back

A cassette tape recorder can easily record sound on and play sound back from tape.

盒式录机可以很容易地用磁带录和放。

To record, press these two buttons together; then rewind, and then press the red button to play back.

要录就得一起按下这个键, 而后倒回, 按下这个红键播放。

When I play back the text, please listen carefully to see whether there are any mispronunciations in it.

我放课文录时请仔细听着, 看里面有没有错误。
