“…It had essentially no commercial circulation, but was a noteworthy technical development. The Phoenix body-worn digital processor developed by Nicolet connected to one or two behind-the-ear units (Hecox and Miller, 1988;Roeser and Taylor, 1988;Sammeth, 1990a (Roberts and Mullis, 1987 Hussung and Hamill (1990), Brunved (1996) and Negroponte (1995) The symbols in the simplest digital code (binary) are reduced to either "1" or "0." As the word bi-nary implies, there are only two symbol choices from which to make decisions.…”

The effects of digital quantization error upon speech intelligibility and perceived speech quality, for normally hearing subjects, were investigated for digitized speech processed to simulate 6-, 8-, 10-, 12-, 14-, and 16-bit integer conversion and 2-, 3-, 4-, 5-, 6-, and 7-bit floating-point conversion. For the integer data, there were no significant differences in speech intelligibility for 8- to 16-bit conversion. Only 6-bit integer conversion at 55 dB SPL resulted in a significant degradation in speech intelligibility. For the floating-point data, there were no significant differences in speech intelligibility for 2- to 7-bit floating-point conversion. However, results of the perceived quality experiment appeared to be more sensitive to differences among the various conditions. Speech processed using 12-, 14-, and 16-bit integer conversion was judged to be superior to speech processed using the 6-, 8-, and 10-bit integer conditions. Speech processed using 5-, 6-, and 7-bit floating-point conversion was judged to be superior to speech processed using 2-, 3-, and 4-bit floating-point conversion.
