Hello Eric,
Welcome to librivox. You have a nice clear voice, I had no trouble understanding you.
I like the expression of your wish to contribute. You should have plenty of opportunity here. Your spoken English is very good. From your name, I would guess you are Korean, but I thought I heard a trace of spanish.

You need to make a change in order to meet Librivox's technical standards.

Required: The volume is too low. You can download the checker program (https://wiki.librivox.org/index.php?title=Checker) which you can use to check the volume against the expected range. This recording was 82 dB, and the normal range is 86-92 dB.

Advisory: There is a little noise. It's not going to bother anybody, but it is also possible to reduce it using noise reduction.
You can highlight the noise in Audacity by changing the track's display mode to "Waveform (db)" using the little pulldown arrow just to the right of the track name. I recommend leaving it there, as I do all my editing in this mode.
Then perform noise cleaning as shown here: https://wiki.librivox.org/index.php/Noise_Cleaning.
I recommend making this a part of your editing routine. You'll be surprised how much difference it makes, but be careful of over-doing it (more than about 18dB), which can affect the quality.

Advisory: your recording is heavy in the bass. This might be because you are speaking very close to the mic. In your place, I think I would
adjust the balance of bass a bit (you can use Effects / bass and treble, or Filter Curve/Equalization), and once you find settings you like, apply
them to every recording you make to create your own "sound".

Please address at least the required technical issue and upload a new version. If you quote this message in your reply, I'll get a notification and will go in and re-check.

If you haven't already, you might spend some time browsing through the LibriVox Wiki. It contains a wealth of great information that you'll find useful and informative about who does what, and various technical aspects.

Thank you for participating in Librivox,
Adrian Stephens

PS - If you're interested in developing your technique, and have the time to spare there's a whole bunch of informative YouTube videos.
Our excellent admin Phil has recorded a lot of highly accessible videos (https://wiki.librivox.org/index.php?title=Instructional_Videos).

I have also recorded a number of YouTube videos on this subject, longer (and thereby going into more detail) than Phil's.
