This means that the voice interface must allow users to command numerical values that are difficult to recognize with high accuracy. Furthermore it is not practical to define fixed rules for each possible number to recognize which means that dictation capabilities must be active when the user wants to command numbers. To avoid noise effects and consequently erroneous recognition a set of rules were added to enable dictation only when necessary having the rule strategy defined above always active. Consequently the following rules were added for robot two the one executing the welding example Rule VI two variables Rule V2 two variables out Rule V3 two variable_name Rule V4 two vanable_name lock Rule V5 two variable_name read enables access to variables ends access to variables enables access to variable_name ends .
