A voice accumulator is a portable system for long-term measurements of voice use in normal conditions. A make contact with microphone connected to your front portion of the neck registers vocal fold vibrations. The purposes of the current study had been: 1) to evaluate the voice accumulator's two measuring applications optimized for registration of elementary frequency (F0) and phonation time,Office 2007 Professional Key (http://www.office2010key.ca/office-2007-key), respectively; and two) to test the voice accumulator for discipline recordings. Four healthful subjects have been recorded in a very sound-proof booth concurrently with one speak to microphone into a voice accumulator and a single get in touch with microphone right into a laptop or computer. When it comes to F0 and phonation time,Windows 7 Professional Key (http://www.msoffice2010key.net/windows-7-key), the results showed that correlations among the voice accumulator's two measuring packages plus a signal-processing method had been high ( r &#83 0.85) for all subjects but 1. The inter-subject variability was large. A prerequisite for reliable vocal fold vibration detection by the voice accumulator was a careful placement and a firm attachment with the make contact with microphone on the neck. Four subjects had been recorded with the voice accumulator during a working day. It was concluded that the voice accumulator is an overall good instrument for measurements of F0 and phonation time,Office Home And Business 2010 Key (http://www.office2007productkey.co.uk/office-2010-key), and thus is useful for both clinical work and research.
