The new Simplicity II recognition system is DSP based and vastly superior over the Simplicity I recognition. Whereas the old recognition system used 80 bytes per word, the new system uses more than 4000 bytes per word. This means there is a lot more data to work with and so the recognition quality has increased 50 fold. Previous clients who are marginal on the Simplicity I systems will now find the Simplicity II systems very responsive. As always however, clients need to be evaluated.
The training for Simplicity II is slightly different than with the Simplicity I systems. In Simplicity I there were 2 word lists each containing 64 words. These were trained one list at a time. In Simplicity II, there are 3 word lists but all words are trained 3 times sequentially.
The new recognition system is built using surface mount technology which results in higher quality and reliability.
