When checked, each chunk is aware of what came before, which may improve performance on interviews. Uncheck for wordlists or short files. Uncheck also if you've tried using Whisper on this file already and the transcript came back with strange repeating loops.

When unchecked, vowels that occur while another speaker is talking are excluded from measurement.

If a vowel is followed by an "L" or "R" within the same word, the two intervals are combined. This, in the case of the word pull, "P + UH1 + L" becomes "P + UHL1".
