SimpleCaptchaAudio

Simple audio support for the simple_captcha.

Installation

Add this line to your application's Gemfile:

  gem 'simple_captcha_audio'

And then execute:

$ bundle

Or install it yourself as:

$ gem install simple_captcha_audio

Usage

The extension adds another parameter to the image generation URL to facilitate the generation of audio file for the same captcha.

Suppose if the URL for the generation for image is http://localhost:3000/simple_captcha?code=3b803d95a91435997917b24046041cc31427aea3&time=1433768850 then simply append audio=true to the above URL to facilitate the generation of the audio file.

So visiting http://localhost:3000/simple_captcha?code=3b803d95a91435997917b24046041cc31427aea3&time=1433768850&audio=true would generate the audio file.

Requirements

• Ruby >= 1.9.3
• Rails >= 3.2
• You need to install espeak, lame and sox system libraries which would help you in the text to speech conversion and exporting the audio to the mp3 format. sox is used for multiple audio files in a single consolidated mp3 file.

You might need to install the above libraries on a Mac-System:

brew install espeak lame
brew install flac sox chromaprint

On ubuntu system

apt-get install espeak lame
apt-get install libsox-fmt-all sox libchromaprint-dev
