Definition

Loquendo ASR is the next-generation speech recognition technology for speech-enabled applications. It is speaker-independent and reliably recognizes large-scale vocabulary continuous speech, even in the noisiest environments such as wireless.

Installation

First you need to contact our I6NET sales team to get a licence. This will allow you to get an access to the download area.

You need these packages:

  • Loquendo License Manager Linux (to generate the license code)
  • Loquendo ASR Linux32 Engine
  • Loquendo ASR Linux32 Languages
  • Loquendo Suite (MRCP server)

NOTE:

You must install the Loquendo Suite in a Fedora/Redhat or CentOs Linux.

To see the actual status execute the command:

sestatus | grep -i mode

The sestatus must be set to disabled, so it will allow SNMP to be started by Loquendo Management Console. To set it, edit the file /etc/sysconfig/selinux changing the row from SELINUX=enforcing or SELINUX=permissive to SELINUX=disabled. Please refer to http://www.nsa.gov/selinux/info/faq.cfm#I1, for details about the SE Linux System.

Unzip and untar the engine package by using the command:

# tar xvzf Loquendo_ASR_7.8-Linux32_Engine_Distribution_7.8.1.tar.gz

Next, go to the directory of the engine directory and type the following command:

# cd  Loquendo_ASR_7.8-Linux32_Engine_Distribution_7.8.1
# ./install.rhel4

Unzip and untar the language packages and install as the engine package:

# tar xvzf Loquendo_ASR_7.8-Linux32_Greek_Distribution_7.8.0.tar.gz
# cd Loquendo_ASR_7.8-Linux32_Greek_Distribution_7.8.0
# ./install

Create a directory to mount the Loquendo Suite iso file:

# mkdir /mnt/virtual

Mount with command:

# mount -t iso9660 -o loop -r Loquendo_Speech_Suite_7.0-el30_Distribution_7.0.8.iso /mnt/virtual

Download of any software package required by the net-snmp 32bit:

# yum install net-snmp

For 64bit installation add:

# yuminstall net-snmp-libs.i386 

Check if your path allow you to reach the snmp command line, if not add:

# export PATH=$PATH:/usr/sbin

Next, go to the directory of the Suite directory and type the following command:

# cd /mnt/virtual
# ./install

See the console results:

# ./install.sh
