The first group of codes (03h – 07h) is due to errors in the way of speaking to the EasyVR or disturbances in the acquired audio signal that may depend on the surrounding environment.
The second group (11h – 13h) indicates an insufficient score of the recognized word (from lowest to highest). Acceptance of lower score results may be allowed by lowering the “knob” or “level” settings, respectively for built-in and custom commands (see CMD_KNOB and CMD_LEVEL).
A third group of codes (14h – 17h) reports errors in the stored commands that may be due to memory corruption. We suggest you check power level and connections, then erase all the commands in the faulty group and train them again.
The fourth group of codes (31h – 39h) deals with errors in message recording, playback or erase.
The fifth group (4Ah – 4Eh) deals with errors in the compressed sound data, either because the wrong version of the QuickSynthesisTM tool has been used to generate the sound table or because a not supported compression scheme has been selected (or data is generically invalid).
The last group (80h – 81h) contains error codes of the EasyVR module itself. Error code (80h = NOTA) means that a word has been recognized that is not in the specified built-in sets. This is due to how Speaker Independent recognition works and can be ignored. Error code (81h = INVALID) is a generic error reported after data validation and currently used for file-system check-up (message recordings).
