1. A method of performing speech recognition on an object for automatic processing of the object by a processing system, wherein the object includes an information area containing a character string of processing information, the method comprising: processing a sequence of characters spoken by an operator corresponding to the character string by way of a speech recognition procedure generating a first ambiguous speech recognition result; based on specific characteristics of the first ambiguous speech recognition result, requesting additional processing information from the operator by providing request information with the processing system; processing an operator's response to the request for generating a second ambiguous speech recognition result; and modifying the first ambiguous speech recognition result to achieve consistency with the operator's response.
