Abstract
This paper presents an application of one method for improving fundamental frequency detection from a speech. The method is based on searching the best pitch paths over one or more words. It uses the idea that the fundamental frequency of a speaker cannot change sharply in a short time so that the pitch should not vary rapidly over one (or a few) words. This technique is created for improving pitch detection. It cannot detect the pitch itself, but it uses some pitch detectors. We compare some of them here and we try to determine which is the most suitable one for our method.
