Performed an intercom check on the ground; between myself and passenger; which was satisfactory. Departed on an introductory training flight as the instructor. It was my second flight using a mask required by our flight school's new COVID-19 related policies and procedures. The route of flight was to be per my normal introductory flight. Turned south towards ZZZ after above a safe altitude. Experienced difficulty communicating with the passenger as my mask was interfering with my microphone. I repositioned my headset's microphone from the outside to the inside of the mask which resolved the communication problem. At this point I identified the road which runs tangentially to the northern edge of the lateral boundary of ZZZ's Class D airspace. After initiating my usual turn to the West to avoid the Class D airspace; I realized that I had mistakenly used the wrong road which was 1 mile south of the correct road and I was now in ZZZ's Class D airspace. I continued turn to a northerly heading in order to exit the airspace and then continued on the introductory flight's route as usual. I was momentarily distracted and failed to maintain situational awareness. As a result; I entered Class D airspace before establishing radio contact. Once the airplane began to turn; the error was apparent and immediately corrected. I should have prioritized tasks and addressed the intercom problem after ensuring correct navigation and situational awareness.
Flight instructor reported difficulty talking to passenger while wearing a face mask and had an airspace violation while attempting to fix the communication issue.
