Beats Per Minute (BPM) Research - PatrickDuncan/cleansio GitHub Wiki
Conclusion
Changes in BPM do not contribute to any significant difference in lyrical accuracy. Almost all trendlines shown in the graphs below are flat. In most graphs, accuracy peak at the original BPM. In the few graphs where the accuracy does not peak at the original BPM, there is no clear pattern among the peaks as some occur in slightly lower BPMs and others in slightly higher BPMs. My guess is that these few peaks at lower and higher BPMs occured because the alteration of the original BPM created cleaner 5-second slices and this resulted in the transcription of a few more words.
