An interpretation system for interpreting electronic signals. The system comprising a central processor for receiving an electronic signal from a user terminal; software for (a) interpreting the signal electronically to reduce errors and (b) identifying parts of the signal that cannot be accurately interpreted electronically. In the event that there are parts of the signal that cannot be interpreted, the system is operable to present at an operator terminal the part of the signal that cannot be accurately interpreted electronically. The operator terminal is such as to allow an operator to interpret the signal and make any corrections that are deemed necessary. Once this is done, the correct interpretation is sent to the user terminal or another pre-determined electronic destination. Also provided are means for automatically adapting the electronic signal-interpretation process when operator assisted interpretation is employed, so as to extend the range of signals that can be accurately interpreted electronically. In this way, the accuracy of the system is continuously and dynamically up-dated.
