Enable overlap

[talentoscope]

Splitting by a consistent chunk length invariably leads to words cut out at beginning and end of transcripts. Is it possible to code in an overlap function, maybe by percentage?

Example: Transcript is 1 hour (60min). Split into 60 x 1 min chunks or use the funk variable to calculate for the below. Allow 5% (variable) overlap to give 63 second chunks, 1.5 secs each side. Output 63 second chunks, centred on the 60 second markers from initial chunk calculation so give %variable overlap at right place.

Can it be done?
