12. A computer system comprising: at least one computer processor; and computer memory comprising instructions stored thereon that when executed by at least one processor cause at least one processor to perform acts comprising: receiving natural language voiced user input into the computer system; deriving a set of one or more terms from the voiced user input, the one or more terms specifying a value to be inserted; determining that the set of one or more terms corresponds to a digital document in the computer system; determining that the set of one or more terms corresponds to at least one computer-executable command, the determination that the set of one or more terms corresponds to the at least one command comprising analyzing the at least a portion of the set of one or more terms using a document-specific natural language translation data structure; determining that the set of one or more terms corresponds to a first element in the document; executing the at least one command on the first element in the document, executing the at least one command comprising entering the value into the first element; updating a second element in the document to produce a value in the second element, with the updating reflecting the entering of the value in the first element, and with the updating of the second element being performed in response to the receiving of the natural language voiced user input; and playing an audible reading of a read-back value derived from the value entered into the first element in the document in response to the receiving of the natural language voiced user input, with the read-back value being different from the value entered into the first element in the document, with the read-back value being a value in a second element in the document, and with the second element in the document being different from the first element in the document.
