Scott, the Commercially Available CMU Wearable was referenced in the post you replied too! It was a long post ;-) The reason why I did not post the link is because its a PDF file and locks up the machine for a few minutes I don't want people clicking on that during a trading day. Message 13272384 is the full text and I can not find link handy now anyway Below is the text which refers to commercially available. I was able to find a picture of the pre-production device on a page form 3 years ago. here is the TIA-P within the CMU site cs.cmu.edu wolff 3.1 TIA-P TIA-P is a commercially available system, developed by CMU, incorporating a 133 MHz 586 processor, 32MB DRAM, 2 GB IDE Disk, full-duplex sound chip, and spread spectrum radio (2Mbps, 2.4 GHz) in a ruggedized, hand-held, pen-based system designed state, the memory architecture is speculated to move 66 MB per second. to support speech translation applications. TIA-P is shown in Figure 4. TIA-P supports the Multilingual Interview System. Speech translation for one language (Croatian) requires a total of 60MB disk space. The speech recognition requires an additional 20-30 MB of disk space. Dragon loads into memory and stays memory resident. The translation uses uncompressed ~20 KB of .WAV files per phrase. There are two channels of output: the first plays in English, and second in Croatian. A stereo signal can be split and one channel directed to an earphone, and the second to a speaker. This is done in hardware attached to the external speaker. An Andrea noise-canceling microphone is used with an on-off switch. TIA-P has been tested with the Dragon speech translation system in several foreign countries: Bosnia (Figure 5), Korea, and Guantanamo Bay, Cuba. TIA-P has also been used in human intelligence data collection and experimentation with the use of electronic maintenance manuals for F-16 maintenance. Operational Experience The following lessons were learned during the TIA-P field tests: wires should be kept to a minimum; handheld display was convenient for checking the translated text; standard external electrical power should be available for use internationally; battery lifetime should be extended; ruggedness is important. All these lessons were used as an input into the design of the optimized version, TIA-0. 3.2 TIA-0 The main design goals for the TIA-0 computer were shrinking the size, reducing the weight, and incorporating the lessons learned from the TIA-P field tests. TIA-0, shown in Figure 6, is a smaller form factor system using the electronics of TIA-P. The entire system including batteries weighs less than three pounds and can be mission - configurable for sparse and no communications infrastructures. A spread-spectrum radio and small electronic disk drive provide communications and storage in the case of sparse communications infrastructure whereas a large disk drive provides self-contained stand-alone operation when there is no communication infrastructure. A full duplex sound chip supports speech recognition. TIA-0 is equivalent to a Pentium workstation in a softball sized packaging.
