1How to create sounds for other languages
2========================================
3
4* Record sounds for 0-9.
5 Speak fast enough to make sound files small. Make sure the level of sound is
6 the same as in the provided samples for English (this is important for making
7 captchas harder to break). Same files in 8 KHz 8-bit PCM WAV format. (To do
8 this in Audacity, set "Project Rate (Hz)" at the lower left corner to 8000,
9 then File > Export, select "Other uncompressed files", click Options...,
10 select "WAV (Microsoft)" for Header, and "Unsigned 8 bit PCM" for Encoding.)

12 If you're not sure if your sounds are okay or how to save them properly, just
13 save one of them into any format (MP3 is okay), and send it to me
14 <dmitry@codingrobots.com>. I'll check it, and if it's okay, I'll ask you for
15 other sounds, and process them myself (in this case, you can stop reading.)
16
17* Put `0.wav` - `9.wav` into the subdirectory with language name (e.g. "ua").
18
19* Open main.go and edit "var langs" on line 21 to include the new directory
20 name.

22* make && ./generate
