Minpair consists of two programs, a C command-line program and a Tcl/Tk GUI, each of which can independently generate a complete list of minimal pairs (words differing in exactly one segment) for use in linguistic research. The GUI may also be used to control the faster CLI program. Both allow sequences of characters to be defined as single segments. Unicode is fully supported. It is also possible to obtain a list of pairs differing in exactly two positions for use in finding phonological rules.
