Preserve the complete text
The planner retains all words in their original order. Check the final group as well as the first; a short ending is still part of the script and should not disappear just to make the sections look even.
Keep the idea with its context
Equal-duration text groups are convenient, but good listening depends on ideas arriving together. Use the segment planner as a first pass and review the points where it splits the script.
Put it into practice
Inspect references across the break
A new segment that starts with 'this' or 'as discussed' may lose its context when reviewed on its own. Move the boundary in your source document or add an accurate introduction. The browser does not perform semantic rewriting.
Rehearse the handoff
Read the end of one section and the start of the next together. Listen for an abrupt topic jump or duplicated setup. Numbered sections help organize files, but they are not proof that the listener will understand each section independently.
A worked example
A boundary splits a question from its answer. Keep them in the same section even if the revised durations become uneven; the purpose is a coherent narration, not equal-size text blocks.
Narration script segmentation and timing planner
A long script is easier to rehearse and review in smaller sections. Enter your measured speaking pace and a target segment length to divide the text into ordered word groups. The planner preserves every entered word and reports estimated minutes for each group.
Segmentation is mechanical at word boundaries, so a break can land inside a sentence. Review the transitions yourself. Estimates do not include silence, pronunciation changes or editing time, and no audio is generated by this page.
