need help with voice recording

please, i need help with the recorded voice files i did at home. can someone suggest any actions or effects i have to apply to them to make them at least 50% comparable to studio quality? a 30 seconds sample is provided.

I’m sure that we can help you to make much better quality recordings.
What equipment are you using? (computer/microphone/version of Windows/etc.) Please give as much detail as possible - make and model numbers are good, plus a description of what is plugged in where with what sort of lead. Too much information is better than not enough.
