CVP Development and Scripting Part 2 (CVPDS Part 2)

CVPD Scripting-Part2 provides in-depth coverage and hands-on practice of the more advanced programming topics of Call Studio such as web services and parsing their results, javascript, modularizing large applications, writing a speech recognition applications, and advanced event handling.

Prerequisites:

• CVPD Scripting Part 1 or Call Studio experience.

Course Outline:

JavaScript: Add a large amount of functionality that was not formerly available:

• String functions: substring, string length, string replace, toUpper, toLower, charAt, etc.
• Math functions: round, floor, ceiling, truncate, random numbers, etc.
• Date functions: date or time arithmetic, validate dates, create formatted date/time variables
• Customize alphanumeric strings for playback using Say It Smart
• Remove invalid characters from data that would otherwise cause errors upon returning it to ICM

REST Web Service calls and XML: Learn to work with RESTful web services

• Use Post Man to test RESTful web service interface
• Learn XPath syntax to parse XML response and test using Notepad++ and free online tools
• Learn XPath expressions that select specific data from XML arrays
• How to use the Studio REST Client Element and to parse XML responses in Studio
• Set fetching properties for the voice browser

REST Web Service calls and JSON: JavaScript Object Notation (JSON) responses from web services

• Learn JSON syntax, how to parse JSON responses, and test using JSONPath.com free online tools
• Learn JSON path expressions to select specific data from JSON arrays
• Use the Studio Rest Client element and JavaScript in Studio to parse JSON results

SOAP Web Services: Understand how to invoke a SOAP and WSDL based web services

• SOAPUI to test web service connection outside of Studio
• Using the Studio Web Services Element
• Learn to parse SOAP responses manually using XPath expressions

Database: Use the SQL Database element in Studio

• Select data and execute stored procedures on a SQL-based database
• Select multiple rows from SQL DB and parse the result using XPath expressions
• Event Handling to catch exceptions and switch to backup database

Modularization and Multiple applications

• SubFlows – Subroutines (or ‘functions) for reusability and readability
• Subdialogs – Calling another Studio application as a subroutine
• Application Transfers – Go to another Studio application without returning

Event Handling: Review of adding event handling globally, in subflows, or element-level

• LastException variable
• Adding Your Own Event Handling for Java Exceptions, VoiceXML Events, Custom Exceptions
• Creating an Error Element to catch any unhandled exceptions

Speech Recognition: Working with Nuance Speech Recognition

• Understanding grammars: builtin, inline, external
• Using Studio Digits, Number, Currency, YesNoMenu elements, Confirm if necessary
• Studio Form Element to build a menu, invoke built-in grammars, point to URI-based grammars
• Work with multiple results (N-Best list) Global Commands (HotLinks)

Record with Confirm

• Learn to write a prompt recorder application to take a recording and allow re-recording
• FTP the recording to one or more media servers
• Understand voice browser cache algorithm
• Understand how to configure cache expiration times on IIS media server
