abstract = "Rhythmic stress detection is an important but
difficult problem in speech recognition. This paper
describes an approach to the automatic detection of
rhythmic stress in New Zealand spoken English using a
linear genetic programming system with speaker
independent prosodic features and vowel quality
features as terminals to classify each vowel segment as
stressed or unstressed. In addition to the four
standard arithmetic operators, this approach also uses
other functions such as trigonometric and conditional
functions in the function set to cope with the
complexity of the task. The error rate on the training
set is used as the fitness function. The approach is
examined and compared to a decision tree approach and a
support vector machine approach on a speech data set
with 703 vowels segmented from 60 female adult
utterances. The genetic programming approach achieved a
maximum average accuracy of 92.6percent. The results
suggest that the genetic programming approach developed
in this paper outperforms the decision tree approach
and the support vector machine approach for stress
detection on this data set in terms of the detection
accuracy, the ability of handling redundant features,
and the automatic feature selection capability.",
