My voice is not audible properly

I speak through my mic couple days back my voice was audible properly but now the voice is less audible feels like I’m speaking from far away or with something like a curtain material in between

Check Audacity is not accidentally recording from the computer’s in-built microphone.

If that’s not the problem, check Windows “audio enhancements” are disabled … Disable Audio Enhancements - Microsoft Support
