We consider the basic possibility of applying the test signals in the form of natural speech in formant-modulation method for estimating speech intelligibility. It is shown that the method of estimating a modulation transfer coefficient, based on the spectral analysis of envelope intensities of test and output signal, provides a plausible results under the action of noise, however, it is practically unworkable in an intensive reverberation conditions.
