Estimate reading or speaking time with separate Latin-word and Han-character rates plus your pauses.

Your input

Outputs are cleared when the input changes.

Result

Enter your data or use the example, then run the tool.

Worked example

The sample has 30 English words and 60 Han characters: 24 seconds at 150 words/min and 300 characters/min.

Method

Intl.Segmenter counts Latin/number word segments, Han code points count separately, and each rate contributes to the total.

Limits

An estimate, not measured comprehension or speech. Other scripts are separately reported and not silently given a Han rate.
