Cedric, you have the library libsrec_jni.so in /system/lib (same size
as mine). Thus I suppose it should be now an option to activate, not a
lib to install.

Natalya, you don't use the Recognizer Intent? Because, if you use this
Intent, I wonder why you want to use it in emulator because there's no
microphone.
