I mean delay in the sense in which it is usually used in the context of music, as in an echoing effect.
I'm sure it is the BPM, as it is displayed that way on the slicer window. Here I have included a JPG of the window, showing that it is actually 86BPM higher than the BPM I selected when creating the speech (which was 200BPM). Also I'm including a short (an very low-quality) MP3 to demonstrate the delay effect. The words are "I am talking."

Incidentally I just found out that by adjusting the number of beats (whatever the hell that means) in the slicer window to 2 or less, I can remove this delay. However that also adjusts the playback rate.
