Casual speech recognition
Due to natural language speech recognition technology, this system enables rec-
ognition of a command when spoken naturally. However, the system cannot rec-
ognize every variation of each command.
In some situations, it is possible to omit the command for the procedure and
directly state the desired operation.
This function is available in English, Spanish and French.
