In order to record the part in your native language you need a translation of the material. One word of advice - although we are all masters of our own language, putting the translated sentences into exact words of your native tongue requires time and energy. It is best to rely on professional translators. The best scenario is to have parallel texts for both native and foreign material you are about to memorize (in addition to the audio version of the foreign part). If not, then you would have to do the translation yourself.

To record the translation part:

Configure your sound card to record from the microphone.

Go to your native language directory, and use record utility mentioned before.

% cd /home/English/Segment12/Russian
% record -o ru12_
	

record starts recording with the offset 0. To align, make dummy first recording by hitting space bar twice. Read your translation sentence at a time into the microphone. At the end you will have a parallel sequence of translation in your native language:
