Measurements have been made to compare the utility of a variety of speech features (amplitude envelope, voice fundamental frequency, second-formant frequency, zero-crossing frequency), and a control based on the output of the TAM aid, for presentation to the profoundly deaf as an aid to speech reception. Segmental information was conveyed adequately by all five signals; suprasegmental (stress) information was conveyed very well by voice fundamental frequency, and significantly less well by the other signals.
