Voice Quality by Eye, Ear and Measurement

Computer facilities now enable complex phonetic laboratory
techniques to be applied for application and hypothesis testing
in the voice clinic. Three developments are described:
Earlier phonetic laboratory single flash stroboscopy, in
which precise timing during the laryngeal cycle is used for
image acquisition, now makes it possible to associate each
image with unique acoustic and laryngographic waveforms.
Two clinical advantages come from this approach: the
images are optimally sharp and their interpretation for the
pathological voice is enhanced.
By using connected speech in addition to sustained sounds
phonetically relevant voice dependent parameters can be
both measured and displayed.
The possibility of linking these methods together in one
combined system then leads to the application of
phonetically motivated speech training methods in which the
techniques of assessment are an intrinsic part of therapy.
