==RUBY-ASTERISK-SPEAKER== This is a ruby on rails application to connect to an Asterisk instance and create voice menus in rails. An added feature is that if you're running it on a mac os X server you can autogenerate speech from any arbitrary text using the applescript gem and the built in speech abilities of Mac OS X. There are a few open source speech generators, but I haven't tried any; this is kind of a proof of concept since not many people run osx server. (Suggestion: Festival via http://github.com/gisikw/acts_as_sayable/) Generally this builds on RAGI (the ragi gem) but with the added ability to pass an Asteriskspeak.speak_text('hello world') or similar call to the play_sound() method provided by ragi. This being a kind of example app, it also uses bits of the Google News library for Rails, which I published a while ago: http://unterbahn.com/2009/08/google-news-library-for-ruby/ So therefore it also requires geokit and httparty. But really you should have httparty installed already, 'cause it's great. Requires the applescript, ragi, httparty, and geokit gems. ==TO INSTALL== First, point your Asterisk system at the server in question. This assumes your Asterisk server is on a different machine. Add the following lines to the default dialplan of your extensions.conf file: exten = s,n,Set(RAGI_SERVER="your.server.url:4573") exten = s,n,agi(agi://${RAGI_SERVER}/ragi/index) (For more on Asterisk dialplans and Asterisk in general, look at the Asterisk O'Reilly book, free downloadable pdf here: http://downloads.oreilly.com/books/9780596510480.pdf) Run the following commands: $ git clone git://github.com/jywarren/ruby-asterisk-speaker.git $ cd ruby-asterisk-speaker $ rake gems:install $ script/server Have fun! Example: play_sound(Asteriskspeak.speak_text('Welcome to News Speak. You will now hear 5 articles from Google News.')) wait(1) index = 1 Googlenews.short(5).each do |article| play_sound(Asteriskspeak.speak_text('Article '+index.to_s)) wait(1) play_sound(Asteriskspeak.speak_text(article['title'])) wait(1) index += 1 end play_sound(Asteriskspeak.speak_text('Thank you. That is all.'))
