Acoustical Implications of Voice Technology in the Open-Plan Office
Abstract
Project ECIOV was designed to answer some of the acoustical
environmental issues presented by the growing number of people implementing
voice input/output with computers. Preliminary testing was carried out
with the Votan VPC2150 voice recognition board to determine the voice level
required for 100% recognition and the effects of background noise on the
recognition rate. It was observed that the Shure head-worn microphone, typically
recommended by Votan and other manufacturers of voice recognition systems,
was effective in minimizing the effects of background noise. The recognition
rate was dependent primarily on speaker level and consistency.
