Asterisk 13, Part 2 of 7

Installing Asterisk 13

In this second of seven videos in our Asterisk + UniMRCP + LumenVox series, we install Asterisk 13, configure some test dialplans for it and run a simple test to verify it is functional and can accept an incoming SIP call.

Installing the UniMRCP Dependencies

Asterisk 13, Part 4 of 7

Installing the UniMRCP library

Asterisk 13, Part 5 of 7

Installing the asterisk-unimrcp Modules

Asterisk 13, Part 6 of 7

Installing LumenVox Packages

In this video, we will go through and install, license and configure the LumenVox packages for our installation, and run a quick test to verify that everything is installed and working correctly.

Testing Everything (plus some tips)

Writing Grammars Part 1

In this first part in our video series on grammar writing, we introduce the basic components grammars and provide clear examples so that new developers can get started building functional SRGS grammars right away.

Speech Recognition 101, Part 2

In the second part of our Speech Recognition 101 video series, we examine grammars in more detail. Grammars provide the "language model" for speech recognition systems, and dictate what sorts of words and phrases a speech application can understand for a given interaction.

Speech Recognition 101, Part 1

Speech Recognition 101, Part 1, is the first part of a video series that delves more deeply into speech recognition than the previous Speech Application Components Video. In this video we cover:

Speech Application Components

The LumenVox Speech Application Components Training Video will give new speech developers a basic understanding of how a typical speech application works. This broad overview briefly describes Grammars, Audio, SSML, Voice Platforms, Media Servers, ASR, TTS and License Servers, along with the role they play within the application and who is meant to supply them.

LumenVox 12.1 Release Webinar

A webinar detailing the changes and enhancements in the LumenVox 12.1 software.

LumenVox 11.1 Launch Webinar

LumenVox Releases version 11.1, introducing two new TTS voices. Learn about these new voices and other new features in this technical webinar.

MRCP vs. API, Part 2

In this second part of our two part series on MRCP versus the API, we delve into the weaknesses of both approaches for developing speech applications and then end with a discussion of which approach might be best for your organization.

MRCP vs. API, Part 1

Before you begin your speech recognition development project, weigh the pros and cons of developing directly to the API or via MRCP. In the first of this two part series, we will define and outline the benefits of each of the paths.

Distributed Architecture

This video discusses the reasons why and the "how to's" of setting up a distributed architecture for speech recognition applications. Specifics include the Client-Server model, the Server Monitor, Licensing and more.

DTMF to Speech, Part 2

Part two of converting your DTMF applications to speech recognition includes a discussion of application styles, such as Directed Dialog and Natural Language applications. In addition, designing prompts and building grammars is also discussed.

Updating SISR Grammars

In this installment of the Semantic Interpretation series, we cover the converstion of previous grammar versions into the new SISR standard. The video covers renamed objects, LumenVox shortcuts, tag formats, and examples.
