Narrative:
Upon landing and clearing the runway xxl at ZZZ; I believed that tower stated 'next left; remain this frequency; taxi to park'. Unfortunately tower actually said 'next left; contact ground point nine' as I played back from the avionics playback function after tower strangely issued me a taxi clearance while I was already taxiing. I read back the (what I thought was a re-issued clearance) and began to question if I heard the initial runway clearing call correctly. After utilizing the playback feature; I realized I taxied without a clearance. With the reduced flight activity of the covid-19 pandemic; I need to slow down; take more time; and be extra cautious. This is amplified by my expectation bias from the past few flights as tower has given me the 'monitor and taxi to park' clearance. Clearance; ground; and tower have all been combined lately due to reduced activity. In many cases; clearance has had us taxi with tower frequency; and such. All the more reason to be extra cautious. Take additional time; and listen carefully as we are all in very non-standard operations.
