Cisco Cisco Unified IP Interactive Voice Response (IVR) 8.0(1) Quick Setup Guide

To check for the current versions of the preceding software supported by your version of Unified 
IP IVR, see the Cisco Customer Response Solutions (CRS) Software and Hardware 
Compatibility Guide. You can access it on the Web at 

Unified IP IVR supports the following subsystems:

MRCP Automatic Speech Recognition (ASR)

ASR Server Software (Required)

ASR ports (at least one is required) 

The number of ASR ports should be less than or 
equal to the number of IVR ports. If there are 
more ASR ports than IVR ports, then the excess 
ports are automatically disabled.

Allows a script to respond to voice input in 
addition to DTMF (Dual Tone Multi-Frequency), 
the signal to the telephone company that is 
generated when you press a key on a telephone 
keypad. 

This allows a caller to verbally convey information 
to the system for processing instead of pressing 
keys on a touch-tone telephone. 

MRCP Text To Speech (TTS)

 TTS Server Software (Required)

TTS Ports (at least one is required)

Composes voice prompts that are generated in real 
time from text, such as speaking the words in the 
text of an e-mail message.

TTS is primarily used to convey information 
obtained from a database or other source that is 
non-repetitive. Examples of such information 
include name and address verification. Repetitive 
information, such as numbers comprising an 
account balance, normally is not conveyed using 
TTS. 

Although text to speech technology has improved 
greatly since its inception, the tone still sounds 
mechanical. So it is best used only when the 
information possibilities make wave file 
generation impossible.

E-Mail

Adds components to the CRS Engine that allows it 
to send e-mail messages

Database

Handles the connections between the CRS server 
and the enterprise database.

Also provides Open Database Connectivity 
(ODBC) support.

for the latest 

versions of the database software that are 
supported.
