Presentation of a preliminary study. An experiment in creating an intelligent room/stage, able to receive verbal and visual input, process this information and act accordingly, taking human-like qualities…sensing?

My role: Developing custom-built voice recognition software, specifically a “sh” detector that allows the dancers to call silence and blackout the lights on stage. After testing several implementations that pattern-matched spectral component distributions over time, I eventually settled on using the autocorrelation function to judge the ‘quality’ of the sound between noise-like or tone-like, thus determining some measure of its periodicity or repetitiousness. Data is extrapolated from this function, local detail is smoothed (slowed down) within the variation of values, and a decision is taken at each moment to determine whether or not the detector will report that a ‘short’ and/or ‘long’ “sh” sound is being voiced at the microphone. The descriptions of ‘short’ and ‘long’ can of course be redefined to suit the sonic purposes at hand..
