5 female English subjects alternated as speaker and listeners in a classic experiment involving the consonants /ptkbdgfvsSzZmn/ in CV utterances, V being the vowel /a/ in 'father'. /S/ and /Z/ are the middle phonemes in 'pushing' and 'measure' respectively. Several S/N and frequency bands were tested, only a few of which are given here.
The 200-5000 Hz one is given as an example :
>> mn5000 = phonmat('html/nicely_plus12db_200to5000hz.dat');
>> mn5000.total
