This paper describes some computational strategies employed in the implementation of the model outlined in papers by Ladd and Ladd & Monaghan in this volume. There are two main categories of problem involved in extracting intonation from text: the first derives from the (currently) very limited nature of higher-level information deducible from text; the second consists of problems of interpretation which would exist even if perfect high-level analyses of text were available. Both these categories can be resolved with reasonable success in our Left-to-Right process model by using various levels of representation and employing computational techniques such as default specification and recursion. Factors affecting intonation at a high level include semantic, syntactic and pragmatic considerations, most of which are not explicit in text. Our model uses a small number of abstract PITCH ACCENT types in conjunction with limited syntactic and pragmatic information and a number of default clauses to generate a wide range of intonation contours.
