I think the likely reason that your mp3 is only being split into 2 or 3 parts rather than the expected 7 is that the silence is not long enough to be detected. The first thing I would do would be to load the audio files into a waveform editor such as audacity, look at the waveform and get an idea of the loudness levels and lengths of each pause between words.

I note from the docs for Audio::FindChunks that it does a lot of smoothing. Perhaps it does to much to the point that consecutive words are smoothed together. Can you adjust the smoothing parameters so that only much shorter periods of audio are smoothed together?

A few years ago, I was cutting mp3 files, but unlike you I did not have handy periods of silence to denote the cut points. Instead I had to listen to the audio, and look at it with a wave editor until I could identify cut points by sight, and then I typed the time offsets into a cut list, and used a lossless mp3 cuter to do the cuts. After a while I became quite skilled at finding the cut points, and typing them in, so if your number of mp3 files is reasonable, you might try that approach, instead of spending more time programming.
