Changing Text-to-Speech Modes

When you use text-to-speech, the mode determines if it reads character strings as words or pronounce each letter separately. The text-to-speech mode is configured using the tts_readmode setting. The following example script demonstrates how to change the text-to-speech mode working in a voice-picking environment.

The following script also repeats picking information from the screen when the user requests it. This script is named sapRepeatPrompts and is designed to work with the script available in Acquiring a Pick Quantity in the Industrial Browser.

Script( sapRepeatPrompts )
String( strPromptBin )
String( strPromptBinValue )
String( strPromptMaterial )
String( strPromptMaterialValue )
String( strPromptBatch )
String( strPromptBatchValue )
String( strPromptQuantity )
String( strPromptQuantityValue )
String( strSearchString )
Number( nReadMode )
Number( nIndex )
