Translation:The place is low.
The TTS says [나씀니다], which is what you are most likely to hear from native speakers when they speak fast, but [낟씀니다] is correct.
The ending 습니다 will sound the same. 낮 sounds like "naht" and "날 sounds like "nahr"
Especially since many words and even the sino-korean numbers are based from chinese. There is even a separate writing system called hanja. Ttmik(talk to me in korean) has started a lesson plan on this now.
For a second, I read "낮습니다." as "늦습니다." 늦습니다, Is to be late, fyi. Just relaying any problems in reading. -_-'
