Method: Commander::UI.converse

Defined in:
lib/commander/user_interaction.rb

.converse(prompt, responses = {}) ⇒ Object

Converse with speech recognition.

Currently a “poorman’s” DSL to utilize applescript and the MacOS speech recognition server.

Examples

case converse 'What is the best food?', :cookies => 'Cookies', :unknown => 'Nothing'
when :cookies 
  speak 'o.m.g. you are awesome!'
else
  case converse 'That is lame, shall I convince you cookies are the best?', :yes => 'Ok', :no => 'No', :maybe => 'Maybe another time'
  when :yes
    speak 'Well you see, cookies are just fantastic.'
  else
    speak 'Ok then, bye.'
  end
end

Notes

  • MacOS only
