%X <p>The article presented a data capacity estimation method for speech information hiding. It uses human auditory system (HAS) model to estimate the data hiding capacity of speech, or the maximum number of bits that can be embedded in speech. MPEG HAS model 1 was modified to estimate the just noticeable difference (JND) for FFT and power spectrum density coefficients. At the same time, a new embedded method that can reach the data capacity was introduced. The maximum number of bits was also calculated that can be embedded in speech to 2 787 bit/s when embedded speech is white noise.</p>
