# Allophonic and Phonotactic Constraints Are Useful

Kenneth Ward Church

*Proceedings of the Eighth International Joint Conference on Artificial Intelligence*, pages 636-637.

## Abstract

This paper argues that allo phonic and phonotactic cues are a source of co nstraint, not a source of noi se as many speech re searchers have assumed in the past. These constraints are formulated so that they can be exploited with well -known parsing techniques.
