Usage

# config/adhearsion.rb
Adhearsion.config.google_tts_plugin do |config|
  config.save_to = "/where/you/wanna/save/speech/files" # make sure you have permissions write
  config.language = "ja" 
  config.speed = "120%"
  config.volume = "130%"
  #config.google_tts = "change here if google changes tts uri" 
  config.mpg123_path = "/usr/bin/mpg123" # change it to your path or nil if not installed (but required on centos)
  config.sox_path = "/usr/bin/sox"       # change it to your path
end


# your CallController
class SimonGame < Adhearsion::CallController
  # make sure you include this line
  include GoogleTTSPlugin::ControllerMethods

  def run
    say "世界の皆さんこんにちわ" # "ja" set at config
    say "hello world!", language: "en" # can change at runtime
    say "hello world!", language: "en", speed: "200%", volume: "200%"
  end
end

tasks

rake google_tts_plugin:seed[csv_file] Downloads .mp3 from google, convert and save in .sln. Since say in your CallController will do this at run time, its initial call can delay and you can prevent it with this task.

text,language,speed,volume
