    Only select specific words! Rule grammar and 3 useful parameters

    Three new parameters have been added to the rule grammar engine of the AmiVoice API, which allows the system to recognize only expressions that follow grammar (rules) set by the user in advance. These improvements allow for further enhancement of recognition accuracy by excluding unsure recognition results, appropriately handling extraneous utterances, and quickly identifying the end of speech.
