The `[0-9a-f].wav` files in this directory contain a human voice |
|
2
|
speaking each of the 16 hexadecimal digits. If a captcha string |
|
3
|
consists of just hexadecimal digits (as is the case for captchas |
|
4
|
generated by the [captcha.c module](/finfo/src/captcha.c)) then these WAV |
|
5
|
files can be concatenated together to generate an audio reading of the |
|
6
|
captcha, which enables visually impaired users to complete the |
|
7
|
captcha. |

Each of the WAV files uses 8000 samples per second, 8 bits per sample |
|

|
and are 6000 samples in length. |

The recordings are made by Philip Bennefall and are of his own voice. |

Mr. Bennefall is himself blind and uses this system implemented with these |
|
14
|
recordings to complete captchas for Fossil. |
