Does the acoustic waveform mirror the voice? A keynote address from PEVOC 6
Over recent decades, much effort has been invested in the search for acoustic correlates of vocal function and dysfunction. We know that the acoustic signal is a rich but in many ways incomplete source of information. Computer literacy and technical curiosity in the voice care and voice performance communities are now higher than ever, and tools for voice analysis are proliferating. On such a busy scene, a review may be useful of basic principles for what we can and cannot hope to determine from non-invasive acoustic analysis. An engineer's approach to a conceptual stratification of the speech and voice production processes is presented.
