Vocalization in dairy animals is thought to be one of the best mean of conversation between each other as well as with environment. The present investigation was carried out on 12 lactating crossbred Karan Fries cows. The vocal signals from these animals were recorded for sufficient time in order to receive 50 complete sound clips. The various acoustic features were extracted in order to establish the relationship between these and various vocal tract or other body related measurements. Call duration of KF crossbred cows in present investigation was found to have a significant (p<0.05) strong negative correlation with circumference of neck. A significant direct association was observed for maximum (p<0.05) and minimum (p<0.01) amplitude with various biometric parameters viz. body weight, heart girth and body length. Moreover, a significant strong negative association was observed for heart girth with mean (p<0.01) and maximum (p<0.05) intensities. Association between 1st fundamental frequency and circumference of neck was significant (p<0.05). Correlation between average formant dispersion and the circumference of neck was also strong, positive and highly significant (p<0.01).
