The objective of this study was to determine the extent to which a cow can be recognized by spectral analysis of her voice independently of her distance from the sound receiver and their relative attitudes.

This was achieved through analysis of the short-time variance of the cow’s voice, to generate a power/frequency spectrum. As with other biological systems it was found that the power/frequency spectrum could be fitted to a straight line on a log-log chart, which was not affected by the cow’s spatial relationship to the sound receiver.

However, simultaneous monitoring of the voices of three cows showed that the system could not separate their voice spectra unambiguously. Other means must be explored for cow identification.
