Simple audio support for the simple_captcha.

Add this line to your application's Gemfile:

  gem 'simple_audio_captcha'

And then execute:

$ bundle

Or install it yourself as:

$ gem install simple_audio_captcha

Use rails g simple_audio_captcha [templatetype] to generate the default template with audio support and overwrite the existing simple captcha template.

Simple Captcha Audio Utilises Espeak to produce audio. The Espeak configuration for voice, pitch and speed can be added to simple captcha:

SimpleCaptcha.setup do |simple_captcha|
  simple_captcha.voice = 'en'
  simple_captcha.speed = 100
  simple_captcha.pitch = 100
end

See espeak documentation for further details for these parameters.

• Ruby >= 1.9.3
• Rails >= 3.2
• You need to install espeak and lame system libraries which would help you in the text to speech conversion and exporting the audio to the mp3 format.

You can install them on OSX from homebrew:

brew install espeak lame

or on a linux based system from your package manager.
