Word prediction assists the communicator by “predicting” and displaying an intended word to select on the keyboard. This saves the communicator time and effort entering all the letters for the word. After the first letter is entered on the keyboard, the Chat software displays a list of words beginning with that letter. As more letters are entered, the list is updated. When the intended word is displayed, select it and it will appear in the Speech Display Bar (SDB). The Chat software then predicts the next word as letters are entered.
The Word Prediction feature has different options/types depending on the communcator’s needs.
Choose a Word Prediction Type
Three types of word prediction are available: Static, Learning, and Learning + Static. In Application Settings, you can choose one of these types of word prediction, or you can choose to disable word prediction.
Go to Menu > Application Settings > Literacy > Prediction > Type. The Prediction Type window opens.
None: Word prediction is disabled.
Static: Word prediction uses the large word prediction dictionary. The settings that apply to learning are not available.
Learning: Word prediction includes the ability to learn, starting with an empty library. This option provides the ability to create a small, very specific dictionary. It is for someone who might benefit from fewer familiar words to choose from. The settings that apply to learning are available.
Learning + Static: Word prediction includes the ability to learn and add words to the large word prediction dictionary. The settings that apply to learning are available.
Choose the Default Dictionary for Word Prediction
The default is the word prediction dictionary that will be used as the basic source of words for predicting. For Static word prediction, all words will come from the dictionary. This allows consistent motor planning for an individual. For Learning + Static word prediction, words you select will be added to this dictionary. North American English and British English dictionaries are available.
Go to Menu > Application Settings > Literacy > Prediction > Default Dictionary. The Dictionary window opens. Select American English or British English.
Add Learned Words to the Prediction Dictionary
Use the Add Learned Words screen to add words directly to the learning word prediction dictionary.
This screen accumulates an alphabetical list of all words you added from all sources—a vocabulary keyboard, the Add Learned Words screen, or an imported text file. Each word is followed by its “count”, that is, the number of times it was entered for learning prediction. This list provides an easy way to review your learning prediction dictionary.
To add a word:
Go to Menu > Application Settings > Literacy > Prediction > Add Words. The Add Learned Words screen opens.
Enter the word you want to add.
Select Add. The word will be added to the list.
Repeat steps 2 and 3 for each word you want to add.
To review your learning prediction dictionary:
Go to Menu > Application Settings > Literacy > Prediction > Add Words. The Add Learned Words screen opens.
Either scroll through the list or enter letters in the text field to jump to specific locations in the list.
Using the Keyboard to Add Words to the Dictionary
Within your vocabulary, select the keyboard button to display the keyboard.
Enter a word that you want to add to the prediction dictionary.
Enter a space or a punctuation mark and then a space after the word.
Repeat these steps for each word you want to add to the prediction dictionary.
If the “Review Required” feature is turned off, the words you entered will now be predicted.
Require a Review of New Prediction Words
You can require review of a new word entered by the keyboard in a vocabulary before the word is added to the word prediction dictionary.
To turn on this setting:
Go to Menu > Application Settings > Literacy > Prediction.
Select Review Required to insert a checkmark, indicating the feature is turned on.
Note: To disable this feature and not require review of new words, select Review Required again to remove the checkmark, indicating the feature is off.
Review New Words for Prediction
The Review Words setting opens the screen from which you can review words before they are added to the word prediction dictionary. Only words entered from the keyboard in a vocabulary will be reviewed. Words added from the Add Learned Words screen or an imported text file will not be reviewed.
Go to Menu > Application Settings > Literacy > Prediction > Review Words. The Prediction Review Words screen lists new words for review.
Each word is followed by its “count”, that is, the number of times it was entered for prediction.
Either scroll through the list or enter letters in the text field to jump to specific locations in the list. To list words in order by frequency of use, select Order by count.
To add the word to the word prediction dictionary, choose the green checkmark. If you do not want to add the word to the word prediction dictionary, select the red X icon.
Ban Words from Prediction
Use the banned words list to prevent specific words from being predicted.
To add a word to the banned words list:
Go to Menu > Application Settings > Literacy > Prediction > Banned Words.
The Prediction Banned Words screen opens.
Enter a word you want to add to the list.
Note: As you enter characters, the display will be limited to words that begin with those characters. This may save you from trying to add a word that is already on the list.
Select Add. The word will be added to the list, followed by the red X icon.
When the list of words is long, either scroll through the list or enter letters in the text field to jump to specific locations in the list.
To remove a word from the banned words list:
Select the red X icon for the word you want to remove.
Import Words to the Prediction Dictionary
You can add words to the prediction dictionary by importing them for learning prediction from a text file (.txt). The text can be in the form of individual words, sentences, or paragraphs.
Create a text file by either the Copy/Paste or Save As method:
Copy and paste: Copy the text you want from your source file and paste it into any text editor (Microsoft Notepad, for example).
If you copy and paste paragraphs: Separate each sentence by selecting Enter or Return.
If you copy and paste individual words: Separate each word by selecting Enter or Return.
Save As: Use Save As from your source file application to save the document as a text file. Then remove the text you don’t want to add to learning prediction. For example, if you use Microsoft Word, select Save As and select Plain Text (*.txt) from the “Save as type” dropdown menu.
If your text is in paragraphs: Separate each sentence by selecting Enter or Return.
If your text consists of individual words: Separate each word by selecting Enter or Return.
Connect a USB cable between the device and the computer.
Using Explorer from the computer, copy the text file to My Files > ChatPC > prediction > import.
After you copy the file, return to the Chat software and go to Menu > Application Settings > Literacy > Prediction > Import Predictions. The Prediction Import screen displays the text file you created with a checkmark
to the right. Select the button with the checkmark. The filename will disappear from the screen, and the words in the file will be added to the word prediction dictionary.
