What is Speech Graffiti? SPEECH GRAFFITI is a special way of speaking that makes it faster for you to exchange information with a computer that understands your speech. Speech Graffiti is easy to learn This tutorial will teach you how. This tutorial uses a flight information system as an example, and afterwards you should be able to use any Speech Graffiti application. Let's get started!

How it works With Speech Graffiti, you speak information in PHRASES just as if you were filling out a form -- one phrase for each piece of information The phrases always sound like this: airline is United…departure city is Pittsburgh…arrival city is Seattle See the pattern? You always give the type of thing you're talking about… then say is… and then state the value you want to specify for that field. When you want to ask a question, you just say… what are (or what is)… and then the thing you want to know about. like this:airline is United…departure city is Pittsburgh…arrival city is Seattle… what are the departure times?

What the system says The Speech Graffiti system will always confirm what it thought it heard you say If the system doesn’t understand a phrase, it won’t confirm it, and it will also play this sound to alert you that it missed something. Then you can simply repeat the missing phrase When Speech Graffiti reads lists of things to you, it plays this sound to tell you that it’s splitting a long list into smaller chunks. Say more to hear the next chunk of the list ! …

Besides entering information in phrases and asking questions, Speech Graffiti has keywords that will help you interact with the system What you can say…

Say start over to erase everything you’ve told the system and begin again Say scratch that to erase just your whole last utterance Ask where was I? to find out what information the system has saved so far …to fix problems

Say help to get general Speech Graffiti help Say options to find out what you can talk about at any point. For example: If you say airline is United, options, you’ll find out about the other things in the system you can talk about: arrival cities, departure times, flight numbers, etc. If you say the name of one of these things and then say options without giving a value, you’ll find out what values that thing can take. For example, airline options would tell you that airline can be United, Northwest, USAirways, etc. …to get help

more – gives you the next chunk of the list next – gives you the next single item previous – gives you the previous chunk first – goes back to the first item in the list last – skips ahead to the last item in the list repeat …to browse lists
