Minimum set for voice recording?

Question

Microphones

Good evening! Please tell me the minimum equipment for voice recording at home. There is a PC, an internal ASUS Soar sound card, an AT2020usb + microphone with a default stand.
Please tell me what you need to buy (filters, screens, external audio, another microphone), the task is to provide high-quality (non-commercial) voice recording for podcasts, including reading literature, etc. It will be the voice that will be recorded, preferably very cleanly and without external noise.
Many thanks to those who help!
PS As a sub-question. Can a Zoom h2n or H5 recorder fit out of the box for these purposes?
