A language learning system comprises a video recording and playing system for playing a recording media, such as a VCR tape, which records a first voice signal of a first speaker and a second voice signal of a second speaker. The video recording and playing system has a first channel and a second channel which are exclusively responsive to the first voice signal and the second voice signal, respectively. A channel selecting device selects at least one of the first voice channel and the second voice channel so that at least one of the first voice signal and the second voice signal is reproduced. As a result, the user can practice conversation with the selected speaker in place of the non-selected speaker.
