Voice dosimeters gather voice production data in the daily lives of individuals with voice disorders. Previously, several voice dosimeters were commercially available. However, these devices have been discontinued and are not available to clinicians and researchers alike. In this tutorial, instructions for a low-cost, easy-to-assemble voice dosimeter are provided. This do-it-yourself (DIY) voice dosimeter is further validated based on performance results. Ten vocally healthy participants wore the DIY voice dosimeter. They produced several tasks recorded by the DIY voice dosimeter and a reference microphone simultaneously. The expanded uncertainty (u) of the mean error in the estimation of four voice acoustic parameters as measured by the DIY dosimeter was performed by comparing the signals acquired through the reference microphone and the dosimeter. For measures of sound pressure level, the DIY voice dosimeter had a mean error of -0.68 dB (u 0.56 dB). For fundamental frequency, the mean error was 1.56 Hz for female participants (u 0.62 Hz) and 1.11 Hz for male participants (u 0.34 Hz). The mean error and uncertainties for the DIY voice dosimeter are comparable to the most accurate voice dosimeters that were previously on the market.
