 ## Why?
 
 For example - some really long task and you just get some coffee, read book or surf internet
 and you want to know when this task will ends, but don't want to check your mac or terminal each minute -
 you can just add small hook in the end of your code and when it will ends - you will hear it with voice that you
-choose from MacOS X `say` function collection.

 You can find some examples of `talks` usage in organization [ruby-talks](https://github.com/ruby-talks):
 
   * [rails-talks](https://github.com/ruby-talks/rails-talks)
   * [bundler-talks](https://github.com/ruby-talks/bundler-talks)
   * [spec-talks](https://github.com/ruby-talks/spec-talks)
 
 ## How?

+On MacOS X this gem just using native MacOS X `say` command line tool.
+On linix/unix this gem using espeak speech synthesis.
 
+### In all examples below I used MacOS X voice types. For espeak you can read section [Using talks with espeak](https://github.com/ruby-talks/talks#using-talks-with-espeak)
+
 ### Configuration
 
 You can configure default voices and messages for `talks` with `~/.talksrc` file or with `your_project/.talksrc` file. It should be written in YAML format:
 
 `~/.talksrc`
 ```yml
 default_voice: 'whisper'
+engine: 'say'
 voices:
   info: 'pipe'
 messages:
   info: 'hello'
   warn: 'WE GONNA DIE!!!'

+### Using talks with espeak
+
+You can configure your `talks` usage even on MacOS X for using [espeak](http://espeak.sourceforge.net):
+
+`~/.talksrc`
+```yml
+engine: 'espeak'
+```
+
+Otherwise `talks` will set engine by default to `say` on MacOS X and to `espeak` on all other OS if command `which espeak` returns something than empty string.
+
+For espeak you have different set of voices and many languages (which this gem not support yet). Voices for espeak:
+
+```ruby
+Talks.voices[:espeak]
+# =>
+  [
+    'en+m1', 'en+m2', 'en+m3', 'en+m4', 'en+m5', 'en+m6', 'en+m7',
+    'en+f1', 'en+f2', 'en+f3', 'en+f4', 'en+f5', 'en+f6', 'en+f7'
+  ]
 ```
