Software for Language Survey

Applications that assist the researcher in language data collection and analysis.


WordSurv was developed jointly by Taylor University and SIL International to help you do comparative analysis of word lists to help determine linguistic relationships.

PalmSurv was developed as a front-end for WordSurv, enabling word lists to be elicited directly onto a PalmOS handheld computer. The elicited data can then be automatically converted on your PC for analysis within WordSurv, making the re-entry of the word lists unecessary.
