Julius zit ook in Synaptic kwam ik achter nadat ik het pakket van de site had gehaald. Ik heb het geinstalleerd, helaas werkt het programma via de terminal en zit er geen gui bij. Wat ik zo las kan je Julius ook als server draaien, ik moet nog uitzoeken hoe je het een en ander aan instellingen kan doen via de terminal. Bijv. de geluidskaart, de microfoon en of er nog wat aan de stemherkenning geregeld kan worden.
