Any number of persons had mentioned the use of a SoundBlaster board for use in a secure voice application for PCs. In the February 17, 1994 issue of EDN, there is an article entitled 'Speech-synthesis and -recognition chips personalize consumer products' by John Gallant, Tecnical Editor, starting on P. 27. There is a company mentioned, ESS Technology, Fremont CA, (510)226-1088, that produces two Sound Blaster register level compatible chips, the ESS488 (without music synthesis) and ESS1488 (with music synthesis). The ESS1488 will run on 3.3 or 5 volt Vdd, and appears to be intended for portable computer applications. Cost per ESS1488 is $18 (presumeably in quantity).
