Thanks for the sample.
No. You’re stuck. The voice is choppy because it went through a noise gate. The silent bits are not just natural room noise, they’re absolute dead digital zero. On top of that is the data compression “talking into a wine glass” sound.
The sound already has a presence boost. Sound around 6000Hz is boosted and if we increase the “clarity,” it’s going to get crinkly paper harsh.
Try Effect > Bass and Treble: Boost Treble 6dB.
