Martial art training with an audio guide

This September I started training in the martial arts, in a discipline called Ryukyu Kenpo Kobujutsu Kai, 
or in short: Ryukyu Kenpo.
http://ryukyu-kenpo.com/
I got my 3rd belt this month: yellow.
One of the ways to progress quickly in martial arts, is to train at home. at the off hours of the dojo.
But I wanted to create a new way to train, so that I will remember all techniques much better.
I wanted some one to tell my a name of a random technique. And I would have to perform it.


But I have no partner to train with, so I decided to create a project:
The goal: To create multiple audio files, each one is saying the name of one technique, with a delay to allow performing it, and than have those files on an ipod, and using the random option, I will be able to train.


The process:
Step 1:
Go to the ryukyu kenpo site. and save all techniques to a txt file.

Step 2:

Remove description of all techniques, leaving only the names.

I did this quickly using a vim macro.

Step 3:

Split the file to many files, each containing one technique.

I used the command:

split -l 1 Martial_arts_techniques.txt
-l 1 - meaning to split the file by single lines


This gave me a lot of files named:
xaa, xab ... xcj

Step 4:
Created a wav file of silence using Audacity

Step 5:


In the folder with multiple text files (xaa,xab...), I entered:
ls -l > filelist.txt
To create a file with the names of all the files, each one in it's own line

Step 6:
I wrote this bash program:


1 #!/bin/bash

2 cat ~/Desktop/filelist.txt| while read line;
3 do name=$(echo $line | cut -c58-70) ;espeak -f $name -w $name".wav"  ; 
4 done

Program explanation:

Line 2: Pump the filelist file to a loop, each iteration, the current technique name is stored in line.

Line 3:Cutting from:

-rw-rw-r-- 1 pentagonpie pentagonpie      32 2012-05-22 12:24 xcc

(The result of the 'ls -l')

only the last part:

xcc 

Then using espeak, converting the text file into an audio file.

saving as program.bash.

Executing using 

bash program.bash

To create a folder with all the text files mixed with the new .wav files

Step 7:

Deleting all txt files:

rm *.txt 

Step 8:

Creating a program similar to the previous.

1 #!/bin/bash

2 cat ~/Desktop/filelist.txt| while read line;

3 do name=$(echo $line | cut -c58-70) ;sox -m $name".wav" final_silence.wav $name"2.wav"  ;

4 done

Line 3: using sox to combine every file with the silence file from step 4.

Step 9:

Importing all audio files to ipod, and using portable speakers.

That is how I done it!
