  1. Spoken Language Support for Software Development Andrew Begel University of California, Berkeley Advisor: Prof. Susan L. Graham

  2. High-Level Code and Commands Programming Language Analysis Source Code Introduction and Motivation • Development mechanisms mostly unchanged for 30 years • Enable people to program linguistically rather than textually • Program by Voice • Intended to help RSI sufferers, as well as students learning to program SIGCSE 2002

  3. Current Tools Are Painful! for statement … next … declare variable name india variable type integer … assign zero … next … recall one … less than ten … next … recall one … post increment … next for (int i = 0; i < 10; i++ ) {  } Program editing and navigation are much worse! SIGCSE 2002

  4. Hard Problems • Disambiguation • User says ARGS SUB ARG NUM PLUS PLUS Possible interpretations: args[arg.num]++ args[arg(num)]++ args[argNum]++ • Must support navigation and editing • Go to the second if statement and replace the predicate by x is less than 7 • Programming languages aren’t spoken • Modify syntax to be easier to say without changing semantics SIGCSE 2002

  5. Cognitive Questions • How do programmers express themselves? • Does everyone speak the same language? • Vocal expressiveness is important: x[i]++ vs. x[i++] • Abstraction is natural • Consistency and correctness are inferred by context • How does speaking affect programming concentration? • How hard is it to learn to program by voice? • How fast or slow can one write code? • What kinds of mistakes are made? SIGCSE 2002

  6. Where are we? • Harmonia-Mode for XEmacs • Provides interactive, on-line program analysis services • Deployed in undergraduate compiler class • Program by voice prototype: Code template expansion by voice • Initial design for Spoken Java language SIGCSE 2002

  7. Conclusions and Questions • Programming by voice won’t be for everyone • How can we apply this to novices? • Will it be easier to learn to code? • Could this change how we teach programming? • How do we study this in a real course? • Next up • Document navigation by voice • Voice-over program comments SIGCSE 2002
