How to correct the spelling of names using Spectrum

Customer is  using Open Parser and giving it name "Robrt Williams".  "Robrt" is incorrect as spelling, It should be "Robert".

Open parser parses input value as per grammar rules written. The functionality of correcting the misspelling is not there in Open Parser.
To acheive this , you can use Table Lookup stage of Data Normalization Module.
The table Lookup component standardizes terms against a previously validated form of that term and applies the standard version. This evaluation is done by searching a table for the term to standardize.
Complete details can be found in UserGuide under section "Module->Data Normalization Module->Lookup Table."
