SpeakServer

말하는 서버. 여러개를 동시에 넣어도 큐에 두고 처리함.

Requirement

OS X proper voice pack.(시스템 환경설정에서 설치 가능)

Usage

$ npm install express NodObjC
$ coffee main.coffee
...

run curl http://localhost:8000/speak/Hello%20World to let server speak 'Hello World'.

TODO

Implement other component that uses this.
