It seems that "To enable FreeTTS support for MBROLA, merely copy mbrola/mbrola.jar to lib/mbrola.jar. Then, whenever you run any FreeTTS application, specify the "mbrola.base" directory as a system property:

  java -Dmbrola.base=/home/jim/mbrola -jar bin/FreeTTSHelloWorld.jar mbrola_us1"

I found this at:
