Occupational voice disorders are observed with increasing frequency in otolaryngological consultations. Devices have been developed that provide objective data on the way individuals use their voices throughout the day outside the clinic. However they do not provide information about the acoustic indexes of voice quality. A critical point is also the choice of the sensor.
   The device here proposed could be defined as a "portable laboratory" for voice analysis, its main advantage being the reliability of estimated parameters from both sustained vowels and running speech. A prototype has been set up on a DSP board and tested on short sustained vowels. Foreseen applications include: basic research, medico-legal, quantification of voice plasticity, vocal function exercises during rehabilitation, voice disorders, short term feedback in singing voice, etc..

Index Terms. voice analysis, dosimeter, portable device, occupational voice disorders
