Abstract

This method provides the most effective voice guide message to each user on the voice speech system. By storing the history of the voice command usage for each user, the voice system can provide the proper guide message in each dialog as the initial prompt.

Method to provide most expected guide for the caller at speech user interface

   In the Speech User Interface (SUI), the user cannot know which voice commands are available in the dialog.

So the voice application must play the guide message as initial prompt for all dialogs. In case there are many usable voice commands in one dialog, or long sentence can be used, the whole guide message may be very long. If the voice system always plays the long guide message, the user must listen whole message until the expected command usage is played.

(Current Implementation)

To improve this problem, the current our voice applictaion has the following mechanism.

At first, all guide messages are separated by level as follows;

<Level 1 command> = Simple/Short command ( 1 or 2 words) i.e. Listen, Send, Reply, etc. <Level 2 command> = have the optional parameters i.e. Listen from Mike, Send as Important, Reply with attachments, etc. <Level 3 command> = long command i.e. Add appointment today from 2 PM for 2 hours. <Level 4 command> = always-active command i.e. help, start over, schedule, etc.

Since there are 2 method for input command on the voice system - voice and DTMF key, the two sets of the guide messages are prepared.

The current appliaction plays the guide messages in order. The user does not have to listen long message and this may be good for the "novice" user. But the command usage of each user is different. The "expert" user who knows basic command and would like to listen level 2 or level 3 guide message must wait until it is played.
