An echo is the reflection of sound waves off hard surfaces, causing them to bounce back to our ears. In an empty room, there are fewer objects to absorb or dampen the sound waves, allowing them to bounce around more easily and create an echo effect.
In general, an empty room will have more echo than a furnished room. This is because the furnishings in a room can absorb sound waves, reducing reflections and echo. Items like furniture, curtains, and rugs can help dampen sound and create a more acoustically pleasing environment.
There is no where for the sound wave to reflect
Sound waves bounce off the walls in an empty room, causing reverberations that create an echo effect. The lack of furniture or sound-absorbing materials in the room allows the sound waves to reflect more easily, resulting in the perception of an echo.
In an empty room, sound waves bouncing off the walls are not absorbed as much, resulting in clearer echoes. In a full room with objects and furniture, sound waves are absorbed and diffused by the objects, reducing the echo effect.
In a furnished room, sound-absorbing materials like curtains, carpets, and furniture can dampen and absorb sound waves, making them less likely to reflect off surfaces and be heard clearly. Additionally, the presence of soft furnishings can reduce echo by preventing sound waves from bouncing around the room and creating prolonged reverberation.
If you are signing in an (otherwise) empty room the sound will echo around you and will possibly sound high-pitched. If you are signing in an empty room then the room isn't empty.

An echo. It is a reflection of sound that can only be heard, and it repeats what is spoken to it.
In a furnished room, sound-absorbing materials like curtains, carpets, and furniture can dampen and absorb sound waves, making them less likely to reflect off surfaces and be heard clearly. Additionally, the presence of soft furnishings can reduce echo by preventing sound waves from bouncing around the room and creating prolonged reverberation.
A period right after the "echo" command would echo an empty line.
Echoes can be heard in environments with hard and flat surfaces that reflect sound waves, such as mountains, canyons, buildings, or empty rooms. When sound waves bounce off these surfaces and return to the listener, an echo is produced.
