Android tts from service

I wrote a little chat client that uses activity and service design fo开发者_运维问答r android.

The main time the client is running, only the service runs in background and notifys for new messages. Now my problem: The service should speak the incomming message with the help of the internal TTS system, but I have no how to build a "new TextToSpeech()" from the service!

Is there any possibility to create one without having an activity? And if, how?
