Narrative:

I was PF (pilot flying) on flight from ZZZ to ZZZ1. During the landing phase of flight approximately 1000 ft AGL; the evacuation alarm began chiming; well in excess of 100 db. The captain; PNF (pilot not flying); attempted to isolate the alarm by silencing the evacuation command before landing; but the alarm would not silence. I landed the aircraft on runway xl at ZZZ1 and transferred control of the aircraft to the captain at approximately 60 kts. At a safe taxi speed and with my after landing flow completed; I noticed that the evacuation annunciator light was illuminated. I attempted to silence the alarm as well; but the alarm continued to sound. Our taxi instruction were to follow a region jet ahead of us to taxiway ss. I subsequently coordinated with ground to taxi to the C holding pad and attempted to silence the piercing alarm; but I had no success. I coordinated with the flight attendant to ensure nothing was wrong in the back and confirmed that they had not activated the alarm. We determined that the PA (public address) system or the crew intercom system was not operational at this point. After some troubleshooting in coordination with maintenance; the captain and I decided to taxi the aircraft to the gate and to turn the aircraft over to maintenance to troubleshoot the system there. We received standard taxi instructions to ss then hold short of T6. I attempted to reduce the noise by covering the evacuation speaker. I was distracted by the noise of the alarm; attempted to cover the speaker with my hand; as well as attempting to coordinate with maintenance when I realized we had missed the turn onto taxiway ss. The captain immediately stopped the aircraft and we coordinated with ground for a new taxi assignment. We then proceeded to the gate with the new taxi route assignment. The alarm only silenced when maintenance removed all power from the aircraft.
