Speech Engine: Only ASR Vendor to Offer 64-bit Support

The LumenVox Speech Engine is an accurate, speaker- and hardware-independent, standards-based speech recognizer that supports multiple languages and performs speech recognition on data from any audio source. The Engine provides speech application developers with an efficient development and runtime platform, allowing for dynamic language, grammar, audio format, and logging capabilities to customize their applications. Grammars are entered in the industry standard Speech Recognition Grammar Specification (SRGS).

Speech Tuner: Easy, Efficient and Powerful Tuning.

The LumenVox Speech Tuner is designed to perform tuning and transcription, instant parameter, grammar, and version upgrade testing of any speech recognition application. It reduces the work of your post-deployment application revisions and allows you to bring tuning in-house, avoiding costly professional service fees.

  • Analyze each stage in the call process.
  • Transcribe audio data, make pinpoint adjustments
  • Test design and development decisions of new applications

What's New in Version 10.2?

Expanded Speech Tuner Tools — A counterpart to our new Text-to-Speech Engine (TTS), the LumenVox Speech Tuner 10.2 now allows users to fine-tune LumenVox TTS settings, view and edit SSML documents, preview TTS output. The new upgrade also sports an auto-complete system for speedier GrXML editing.

Text-to-Speech: The Most Realistic Voices on the Market

The LumenVox Text-to-Speech Server (TTS) provides text-to-speech synthesis, turning written text into spoken speech. It supports the Speech Synthesis Markup Language (SSML), a way to format text within XML to control the pronunciation of words, but it can also accept plain text in order to perform synthesis. As with the LumenVox Speech Engine, the primary method of interacting with the TTS Server is through the Media Server.

The TTS Server requires one or more voice packages, which are additional modules that can be downloaded and installed in a manner similar to the LumenVox Speech Engine's language packages. These voices provide support for different languages and also provide different voices for a single language. For instance, American English has support for a variety of male and female voices to suit a user's exact needs.

AMD: Tone-Based for Highly Accurate Message Delivery

LumenVox's Answering Machine Detection (AMD) technology delivers outbound messages by detecting answering machine and voicemail tones. The AMD is tested at 94%* accuracy.

Our tone-based detection is a significant innovation compared to many other energy-based answering machine detection technologies. The LumenVox AMD actually listens to tones facilitating more reliable and highly accurate message delivery.

Since LumenVox is listening for the beep, your outbound dialing application won't know it's connected to a voicemail system at the beginning of a call. With higher tone-detection accuracy your message sounds more professional because it starts precisely where it should.

*94% measured in large scale testing, based on recordings of actual calls. Accuracy may vary.

LumenVox Professional Services

Our Professional Services Team will navigate you through the stages required to develop a world-class speech recognition application. Whether you're just starting out, have an existing speech application, or want to implement new speech solutions to an existing platform, we offer a wide range of professional services to meet your needs. Our team can integrate in at any time and assist you at every development stage: Discover, Design, Develop, Deploy. Just ask us how. When other vendors say "No," we say, "Let's Make It Happen!"

LumenVox Design Workshops

If you're considering building a new speech application or revising an existing one, engaging LumenVox at the beginning of your discovery process can save time and money down the road.

Our discovery process begins with a Design Workshop between your Stakeholders and our Solution Architects. In the Workshop we'll address the business and technical objectives of your proposed speech application and perform a complete assessment of your current infrastructure. The Design Workshop provides the roadmap for creating the best possible solution to meet your needs.

LumenVox Solution Documentation

Based on the discoveries and infrastructure assessments gained from the Design Workshop, we'll build a complete Solution Document that includes full technical and functional specifications for the development of your Speech Application. By working closely with you during the Design phase we can ensure that developers spend their valuable time pursuing the optimal paths which align with your strategic and technical goals.

LumenVox Development Cycles

Once the Design Phase is finished, we'll initiate a concentrated series of iterative Development Cycles, giving you regular feedback to ensure that our development efforts meet with your specific needs as outlined in the Discovery and Design phases.

During the Development Phase we build automated unit tests and write test scripts so that we can efficiently and reliably perform regression testing on your Speech Solution. This test-driven Development Methodology delivers rock-solid applications trusted to perform as they are intended to.

LumenVox Hosted or
Premise-Based Deployment

Finally, we'll work with you to deploy your new speech solution as a hosted or premise-based application. Once the hosting platform is selected we'll performance test your application to make sure it's working properly. And if you're hosting with LumenVox we ensure 24x7 monitoring tools to meet strict uptime requirements.

Additionally, the LumenVox Speech Tuner 10.1 can be utilized to fine tune the application and grammars to achieve the highest possible performance levels, transcribing user responses and analyzing its success.

LumenVox, LLC, an innovator in speech recognition technology, announced today the release of version 10.2 of the LumenVox Speech Engine.

What is Speech Recognition? Speech recognition, often called automatic speech recognition, is the process by which a computer recognizes what a person said. If you are familiar with speech recognition, it ’s probably from applications based around the telephone.

Types of Speech Recognition There are two types of speech recognition. One is called speaker-dependent and the other is speaker-independent. Speaker-dependent software is commonly used for dictation software, while speaker-independent software is more commonly found in telephone applications.

Uses of Speech Recognition Speech recognition applications are different from any other kind of computer application. It opens up a world of possibilities for developers, especially those building IVRs and other telephony applications, but speech recognition also has some challenges.

Natural Language and Directed Dialogue Designing a good speech application is often a balancing act between accuracy and flexibility. Nowhere is this balancing act more evident than in the two general ways of letting users respond to speech applications.

DTMF to Speech White Paper In this paper we will cover some techniques and tips you can follow to convert your DTMF application to speech -- and delve into the reasons for taking the plunge in the first place! With careful planning and a methodical approach, you can leverage speech recognition technology to bring increased caller satisfaction and improved customer service to your organization.

Distributed Architecture Speech recognition applications in telephony environments not only require increased processor load but are also mission critical and "down time" is not an option.

All About Grammars At the heart of speech application development is the grammar, the list that defines which words a speech application can recognize. Grammars will influence — and be influenced by — many other facets of a speech application, including prompts, menu choices, and the overall call flow of the application.

Leveraging Information to Increase Call Completion in Speech Recognition Application The goal of a speech recognition Interactive Voice Response (IVR) system is to successfully provide and/or capture automated data through to call completion.
