I can hear it just fine, even with relatively low speaker volume.
As an aside, an extremely good sound recording and manipulation app is (free) Voice Record Pro that allows instant editing--clipping, amplification, etc. Apple Android
Yes, I can hear it fine in Firefox, PaleMoon won't play it though for some reason.

Typical three repetitions of each phrase LOL
Merlin already makes pretty good recordings at 44.1 kHz sample rate with a 16-bit depth. That's audio CD quality. It's problem is that there's no gain setting. You should post-process your recording with a free software like OcenAudio or Audacity. At a minimum, trim and normalize. Excellent guidance here:

It's no more difficult than editing photos once you have your work flow down.

I checked out voice record pro, and it appears to be out of date for Android. I don't know your platform.
Bummer that Voice Record Pro is out of date on Android. Still being updated for Apple. One of the truly excellent iOS apps.
