The first step to make Brad or Rachel say something new is adding the line to the .plist file that NPCEditor uses to store its data.

1. Launch NPCEditor using the Launcher:
   1. Hit Advanced.
   2. Click on the green arrow in the NPCEditor line in the Agents section.
   3. Note that the NPCEditor will launch minimized and may be grouped with other Java processes.
2. In the NPCEditor, select the Utterances tab. On the right side in the Answers column, click the "Add" button. A new blank line will be created in the list.
   1. Note that once you make changes, you will be prompted to save the .plist file. It is best to save under a new name. You can disable automatic saving in the Edit menu, Properties.
3. Type the dialog you want Brad to say in the text box at the bottom.
   1. Image Added
   2. Note that you may need to adjust the GUI to see the correct text field; it's the one right below the buttons. You can ignore the Script section for now.
   3. Note that while you can paste in text, but you need to make sure it doesn't contain any special punctuation marks, such as those found in MS Word or Excel. Typed in punctuation should be fine.
4. Fill in the External ID.
   1. If using prerecorded speech, this should be the audio file name without the extension (i.e. test, not test.wav).If using TTS, this
   2. All External ID's should be something unique. 
5. Fill in the other information:
   1. 'Domain' is 'General' or whatever domain you want the line to appear in.
   2. 'Toss' is used for jumping between domains and can be ignored for now.
   3. 'Type' can be blank or one of the control types.
   4. 'Speaker' should be 'Brad' or your character's name.
   5. 'Addressee' should be 'User'
   6. 'Topic' is not required, but useful for organization.
   7. 'Sound' is used to sort between prerecorded or TTS lines, set accordingly.
6. You may test the line by double-clicking on it in the Answers list, provided the rest of the Toolkit is running.

When using Unity, the audio files are kept in \Assets\StreamingAssets\Sounds under each Unity project.  Any Any audio file that Unity can playback play back can be used.  The The file name needs to match the External ID used in NPCEditor (see above).

If the audio file cannot be found, the system will try to generate the audio using TTS.
