Gradint is a program that can be used to make your own self-study audio tapes for learning foreign-language vocabulary. You can use it to help with a course, to prepare for speaking assignments, or just to keep track of the vocabulary you come across.
The method: Gradint uses a variant of the “graduated-interval recall” method published by Pimsleur in 1967. It’s like audio flashcards that appear in a special pattern designed to help you remember. The Pimsleur accelerated language courses use several techniques (they say some are patented), and *Gradint does not imitate all that*, but this particular 1967 idea is now in the public domain so Gradint can use it to help you learn your own choice of vocabulary.
Gradint gives *only* audio, so you concentrate on pronunciation. (And so you can listen during daily routines e.g. washing etc, since you don’t have to look or press buttons during a lesson.) Gradint can write its lessons to MP3 or similar files for you to hear later, or it can play them itself and try to adapt to emergency interruptions. The words it uses can be taken from real sound recordings or they can be synthesized by computer. You can add words to your collection at any time, and Gradint can manage collections of thousands of words (and supports batch entry). It can also help you rehearse longer texts such as poems.
Gradint is free/libre and open-source software.
1. Download the appropriate version:
If you are learning Chinese, you might also want Yali Cheng’s Mandarin voice (hear a sample) or a lower-pitch version of Yali’s voice or Cameron Wong’s Cantonese voice. These are larger downloads but less “robotic” than the voice that comes with Gradint. On Windows just open them; on other systems put them in the same folder as you put Gradint.

2. Tell the program which language you want to learn. On most systems, Gradint will show a GUI which lets you do this. A more technical way to do it is to edit the file settings.txt.
3. Give the program some words and phrases to teach. This can be any combination of real recordings and computer-synthesized words, and you can always add more later. You can use the graphical interface (on supported systems), or you can:
the file README.txt in the samples directory
4. If possible, prepare some audio prompts such as “say again” and “do you remember how to say”. These can be real recordings or synthesized text. Some text for English and Chinese is already provided, but if you won’t be using a speech synthesizer you can download sampled English prompts. For any other language you should ideally add your own; for details of how to do this, see the file README.txt in the prompts subdirectory of the samples directory.

You should then be able to run the program every time you want a lesson.
You can do more advanced things if you are able to edit configuration files. For details see the file advanced.txt (that link is for reference only; to make changes you will need to open the copy in your gradint installation).
For programmers: The source code is gradint.py which can be found within any of the downloads, or you can download the Gradint build environment which contains a Makefile and supporting files for producing the above releases from a Linux box. See its README.txt for details. There is also an SVN repository thanks to Cameron Wong: svn co http://svn.code.sf.net/p/e-guidedog/code/ssb22
