A tool for learning vocabularies.

This tool will pick vocabularies randomly from new-words.txt, play sound files from cambridge.org, and show definitions.

Run the following command to start the tool. It will show a vocabulary on the screen.

$ ./learn-words.sh

Everytime you press 'ENTER' key, it picks another vocabulary from new-words.txt for you.

Pressing 'a' key, it will play the audio file of the current vocabulary. You can play the pronunciation as many times as you like.

Running the tool with the "-a" parameter, it will play pronunciations automatically.

Pressing 'd' key, it will show the definition of the current vocabulary.

Pressing 't' key, the current vocabulary will be added to tagged-words.txt. Pressing 'T' key, the current vocabulary will be remove from tagged-words.txt.

By maintaining tagged-words.txt, you can revise only vocabularies in this file by running the following command.

$ ./learn-words.sh -t

For some vocabularies, you want to learn them more often than others.

Pressing 'r' key, the current vocabulary will be added to reinforce-words.txt. Pressing 'T' key, the current vocabulary will be removed from reinforce-words.txt.

The vocabularies in reinforce-words.txt have higher chance to be picked by the tool.

By default, every 20 times, it will show one reinforced vocabulary in average. It can be changed by passing a "-r" parameter.

$ ./learn-words.sh -r 15 # one reinforced vocabulary every 15 times.

You can query the definition of a new word whenever you want by starting with ":" and following with the vocabulary.

For example, the following sequence is to check the definition of "monkey".

:monkey

The vocabulary will be added to new-words.txt too.

You can extract vocabularies that you have asked to cambridge.org or several other sites from the history databse of firefox with the following command.

$ ./firefox-history.py -t

It will show a list of vocabularies. You can start with adding the list to new-words.txt.
