13. In a speech recognition system, an apparatus for storing speech parameters, said apparatus comprising: transducer means responsive to acoustic energy for transforming said acoustic energy into analog electrical signals, wherein said acoustic energy comprises voiced speech, unvoiced speech and background noise; signal processing means for converting said analog signals to substantially equivalent forms of speech parameters and for sampling said speech parameters at a predetermined sampling rate; a binary adder coupled to said signal processing means for computing the average signal level of samples of said speech parameters from said signal processing means during predetermined periods of time; storage means coupled to said signal processing means for receiving speech parameters, said storage means comprising a plurality of m contiguous blocks which are consecutively and ordinally numbered first through mth, each of said blocks comprising an equal number of storage locations, said number of storage locations corresponding to the number of samples of said speech parameters operated upon by said means for computing average signal level during each of said predetermined periods of time; means coupled to said storage means for generating sequential addresses corresponding to individual storage locations of said storage means to permit storage of said speech parameters therein; and control means coupled to said storage means and said address generating means and responsive to said binary adder for: (a) transferring speech parameters resident in the storage locations of the second through nth blocks of said storage means into corresponding storage locations of the first through (n-1)st blocks, respectively, of said storage means; and (b) resetting said generating means to thereby cause it to address the initial storage location of the nth block of said storage means; where n is a number substantially smaller than m; when the average signal level computed by said binary adder during any of said predetermined periods of time fails to exceed a predetermined signal level.
