LumenVox is a privately held speech recognition software company, based in San Diego, California. LumenVox has been described as one of the market leaders in the speech recognition software industry[1] and is the second largest provider of speech recognition software according to industry analysts.[2]

History

LumenVox was founded in 2001 as subsidiary of Progressive Computing. According to LumenVox CEO Edward Miller, when Progressive had initially looked to add speech recognition to its own phone system, it found the existing offerings too expensive and recognized a niche in the market for a more affordable speech recognition product. This led to the development of LumenVox with an aim to bring speech recognition to small-to-midsized businesses.[3]

LumenVox is one of the major providers of automatic speech recognition for telephone systems, and as of 2006, became the second largest provider of speech recognition software.[2]

On September 19, 2018 LumenVox announced they were merging their operations of LumenVox, LLC and VoiceTrust GmBH, adding biometric authentication to their speech automation suite.  By combining the deep expertise of multi-modal biometric authentication from VoiceTrust together with the high-performance core speech capability of LumenVox, LumenVox now has an integrated highly intuitive speech interface solution for virtually any interactive computing or telephony task. 

With the merger of Voice Trust, LumenVox is fast becoming the total speech solutions technology company. Combining a European presence, deep funding from Ramphastos Investments and a seasoned team, LumenVox is now able to provide a more comprehensive stack of speech and speaker recognition technology, enabling them to grow more deeply into the enterprise and hosted cloud space.  They currently support a multitude of applications for voice, biometric authentication, fraud prevention and public security by selling direct, through the channel and with partner organizations worldwide.

Products

The primary LumenVox product is the LumenVox Speech Engine. It is a speaker-independent automatic speech recognizer that uses the Speech Recognition Grammar Specification for building and defining grammars.[4] It has been integrated with several of the major voice platforms, including Avaya Voice Portal/Interactive Response,[5] Aculab,[6] and BroadSoft's BroadWorks.[7] The Speech Engine was originally derived from CMU Sphinx,[8] but LumenVox has added considerable development effort to make it a commercial-ready product.[9] Refer below for full summaries of each of our products.

Automated Speech Recognizer

The LumenVox Automated Speech Recognizer (ASR) is a software solution that converts spoken audio into text, providing users with a more efficient means of input. Less time spent in data input frees up resources that can be used more effectively. The LumenVox ASR is integrated with more than 25 voice platforms (i.e. Asterisk, Avaya, Cisco, Genesys, etc. ). Developers can write applications using our application programming interface (API) or a standards-based solution like media resource control protocol (MRCP). This makes installation, implementation and deployment easy for users of those platforms.

Text-to-Speech Engine

LumenVox Text-to-Speech (TTS) technology is available offering the most realistic, natural sounding speech on the market. The LumenVox Text-to-Speech (TTS) Server is a complementary solution to our LumenVox Speech Recognizer (ASR), enabling your application to synthesize text-to-speech to create the most realistic, natural sounding voices on the market.  The LumenVox TTS Server is designed to excel in telephony, Interactive Voice Response (IVR), and other similar command/ control environments. So whether you are speech enabling a call router or looking to develop applications for the burgeoning mobile market, LumenVox has the full suite of products you need.

Call Progress Analysis

LumenVox’s new Call Progress Analysis (CPA) increases the effectiveness of your outbound messaging application. LumenVox CPA analyzes the audio during call startup, scanning for telephony messaging tones. When the call is connected, it automatically begins to listen for fax or voicemail tones. With it, you can rest assured that your predictive dialer or IVR is getting the right message to the desired recipient more accurately than ever. The LumenVox Call Progress Analysis solution leverages the strength of our Speech Recognizer by constantly listening for various tones, just as it would when performing speech recognition. These are compared to special acoustic models for matches, similar to our ASR’s function. The result is more reliable and highly accurate message delivery.

Speech Tuner

The LumenVox Speech Tuner, a complete tuning and maintenance tool. It performs transcriptions, instant parameter and grammar tuning, and version upgrade testing of any speech application. If your ASR application is commonly misrecognizing words, the Tuner can help you edit the grammar or test configuration changes. When you need to write new SSML for your TTS solution, the Tuner can check its syntax. Tuning uses prompts, grammars, call flow, and caller data to improve the speech application performance. Without regular cycles of tuning, most speech applications are destined to suffer from the same problems, leading to unhappy users. Tuning resolves that by allowing administrators the ability to correct mistakes in their application. It reduces the work of your post–deployment application revisions, and allows you to bring tuning in–house, avoiding costly professional service fees.

Multifactor Biometric Authentication

Voice biometrics provide a security layer that prevents unauthorized account logins, reduces your exposure to data breaches, and delivers a convenient login experience to your end-users across web, mobile, and desktop applications. Biometric login can help your customers and employees by providing a safe second- or third-factor authentication method which they will much prefer.

Automated Password Reset

Empower your customers and employees to reset their passwords without the involvement of a help desk agent. Save them from having to remember security questions or PINs that are easily lost or shared. Reliably authenticate your users anywhere and anytime with a simple spoken phrase.

Awards

Lumenvox has won numerous awards for innovation and technical excellence. Based on industry standards, LumenVox' core Speech technology is certified as one of the most accurate, natural sounding, and reliable solutions in the industry. The LumenVox technology provides tools for you to effectively deploy speech-enabled applications to improve the Call Center CX and ROI with LumenVox' flexible, cost-effective software suite.

Open Source Support

LumenVox was recognized as one of the top VoIP companies in 2008 for its work in providing its offerings to the open source community,[10] an effort by the company that began in 2006 when it partnered with Digium. At that time Digium, maintainer of the open source Asterisk PBX, integrated the LumenVox Speech Engine into Asterisk. This made LumenVox the first commercially available speech recognition engine for Asterisk.[11]

As one of the earlier commercial software integrations with Asterisk, the LumenVox integration has been described as one of the applications that helped to mainstream Asterisk.[9][12][13]

Because LumenVox is generally recognized within the speech recognition industry as one of the most affordable speech recognition products,[1] the LumenVox Speech Engine was able to meet a need for low-cost speech recognition within the open-source community.[14] In 2009, LumenVox also began offering access to the Speech Engine as a monthly subscription, bringing the cost of entry down even lower for open source users.[13][15][16]

LumenVox is also integrated with the open source UniMRCP project, which provides open source client and server libraries for the Media Resource Control Protocol.[17][18]
