<p>utrecht</p> <p><b>New page</b></p><div>Fluctuations in [[pitch]]. Excessive jitter makes a [[voice]] sound creaky (see [[creaky voice]]). <br /> <br /> '''Mean absolute jitter''' is the mean absolute difference between sequential vocal periods measured during a sustained phonations (in seconds or milliseconds). However, absolute jitter is influenced by the mean fundamental frequency of the speaker. For this reason, relative jitter measures have been proposed. '''Mean jitter factor''' is the mean absolute difference between sequential vocal fundamental frequencies (in [[Hertz]]) divided by the mean frequency of the phonation.<br /> <br /> === Link ===<br /> <br /> [http://www2.let.uu.nl/UiL-OTS/Lexicon/zoek.pl?lemma=Jitter&amp;lemmacode=1227 Utrecht Lexicon of Linguistics] [http://www-uilots.let.uu.nl/~audiufon/data/bronparameters.html#demojitter Audiodemonstration jitter]&lt;br /&gt;<br /> <br /> {{dc}}<br /> [[Category:Phonetics]]</div>
