Abstract : An attempt was made to assess emotional stress through voice analysis. The involuntary vocal musculature microtremor, which has been reported in some literature as correlated with stress, was chosen as the variable for analysis. An autocorrelation technique was developed using a CD&A array processor installed in a DEC PDP 11/34 computer. Although the technique isolated frequency modulatio,(FM), the microtremor was not identified, primarily due to excessive noise in the 5-15 Hz frequency band of interest. (Author)
