RecognizerIntent.ACTION_RECOGNIZE_SPEECH - no activity found to handle it on emulator

I am trying speech recognition feature on android emulator but when I try to launch recognizer intent on my emulator with 2.1, no activity is present. Why is it not available out of the开发者_如何学JAVA box? Is it normal? Is it possible to install support?

Thanks

It seems that emulator has not Speech Recognition feature yet. To solve partially the problem it is possible to download the system image from http://developer.htc.com/adp.html and substitute it to android 1.6 system.img of the emulator. This makes speech recognition enable.
