- A database utility (find_phone) to automate speech database related enquiries. It allows the user to specify a particular label or set of labels in a given context, display all occurrences of the label, and relabel the occurrences if desired.
- A Vector-Quantizer based on the Linde Buzo and Gray (LBG) algorithm.
- A set of PERL Scripts which have been used mainly to automate the use of the OGI Speech Tools.
- MAN Pages for all routines and programs developed, as well as a User manual in both in postscript and tex format.
