Audio and Image CAPTCHAs are in seprated modules:

from captcha.image import ImageCaptcha

audio = AudioCaptcha(voicedir='/path/to/voices')
image = ImageCaptcha(fonts=['/path/A.ttf', '/path/B.ttf'])

data = audio.generate('1234')
assert isinstance(data, bytearray)
audio.write('1234', 'out.wav')

image.write('1234', 'out.png')

This is the APIs for your daily works. We do have built-in voice data and font data. But it is suggested that you use your own voice and font data.


We need voice wav files. The voice wav file should be in 8-bit, please keep it as small as possible. Name your voice file as:

# exmaple: zh-1-lepture.wav

TODO: we need a place to upload voice files.
