Final Proposed Vocabulary and Grammar

       A detailed survey was developed and administered with the purpose of gathering the feedback from the programming community regarding alternative options for the proposed vocabulary and grammar.  The questions selected for the survey represent an assortment of programming commands that fall under each of the programming control flow structures: Sequential Structures; Decision or Conditional Structures, and Looping or Repetitive Structures.  The participants were students of Computer Science and Computer Engineering  from the University of Puerto Rico and the Polytechnic University of Puerto Rico. 

       After performing a qualitative and quantitative analysis of the results obtained from the survey, which contains 10 questions (each one is a multiple choice featuring two or more possible verbalizations of the code and one write-in answer slot for alternative suggestions), a final version of the grammar and vocabulary was proposed, and is presented in Table 1. It is expected to be embraced by the programming community.

       The proposed voice command is written in bold, arial, and red, the corresponding C++ code, as a consequence of the voice command, in italics, bold, and black (this is the output produced by the voice-recognition software in an editor), and variables and literals presented in italics, and green.  

Table 1: Final Proposed Vocabulary and Grammar      

Programming structure	Voice commands
Variable definition	defining integer variable             int ; total             int total;
Standard output: literals	printing literal             cout << “ ”; hello world            cout << “ hello world”;
Standard output: variables	printing variable             cout << ; total             cout << total;
Mathematical operations	printing             cout << ; grouping             cout << () ; total adding 2             cout << ( total + 2 ) ; moving right, symbol frontslash 4             cout << ( total + 2 ) / 4 ;
Standard input	getting input into variable total cin >> total;
Modulus operations	total modulus 3             total % 3
Relational operations	total symbol greater than seven total > 7
Logical operations	(statementA) operating and             (statement) && negating (statementB)             (statement) && !(statement)
Loops	inserting for loop             for ( ; ; )             {             } inserting initiation (initializeExpression) inserting condition (conditionalExpression inserting modification (modifyExpression)             for ( initializeExpression; conditionalExpression; modificationExpression)             {             } entering loop (statement(s))             for ( initializeExpression; conditionalExpression; modificationExpression)             {                         statement(s);             }
Conditionals	inserting conditional if() { } inserting condition total symbol greater than seven if( total > 7) { } printing literal eight if( total > 7) { cout << “8”; } else printing literal six if( total > 7) { cout << “8”; }else { cout << “6”; }
