Az-eddine Haida

Hi, i'm new with linux and SBC. My final goal is to use the board as a voice command recognition system (without display) and to be honest i do not know how to start. I downloaded Armbian desktop on microSD using balenaEtcher and I inserted it in the board e powered it! i do not have a display unfortunatly and i do not know if desktop version is the best choice or i have to install an embedded version if exists. Could help please? thanks
