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.{{Cite web|url=http://www.speechtechmag.com/Articles/Editorial/Q-&-A/Ed-Miller2c-CEO2c-LumenVox-35322.aspx|title=Interview with Ed Miller, CEO, LumenVox|date=October 1, 2002|publisher=Speech Technology Magazine|accessdate=March 5, 2010}}
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.{{Cite web|url=http://www.thestreet.com/s/nuance-buys-new-york-software-firm/newsanalysis/techsoftware/10382384.html?puc=_googlen?cm_ven=GOOGLEN&cm_cat=FREE&cm_ite=NA|title=Nuance Buys New York Software Firm|last=Lessner|first=Ivy|date=October 2, 2007|publisher=TheStreet.com|accessdate=March 5, 2010|archive-url=https://web.archive.org/web/20110606005905/http://www.thestreet.com/s/nuance-buys-new-york-software-firm/newsanalysis/techsoftware/10382384.html?puc=_googlen%3Fcm_ven%3DGOOGLEN&cm_cat=FREE&cm_ite=NA|archive-date=June 6, 2011|url-status=dead}}

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,{{Cite web|url=http://www.fiercevoip.com/special-reports/lumenvox-top-voip-company-2008-fiercevoip-fierce-15|title=LumenVox, Top VoIP Company 2008: FierceVoIP, Fierce 15|date=November 4, 2008|publisher=FierceVoIP|accessdate=March 5, 2010|archive-url=https://web.archive.org/web/20101225224131/http://www.fiercevoip.com/special-reports/lumenvox-top-voip-company-2008-fiercevoip-fierce-15|archive-date=December 25, 2010|url-status=dead}} 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.{{Cite web|url=http://www.lumenvox.com/news/lumenvoxNews/2006/031306.aspx|title=LumenVox and Digium Partner to Offer Speech-Enabled Asterisk|date=March 13, 2006|publisher=LumenVox|accessdate=March 5, 2010}}
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.{{Cite web|url=http://www.vonmag-digital.com/vonmag/20080102/?pg=38|title=Advanced Applications of Asterisk|last=Mohney|first=Doug|date=January–February 2008|publisher=VON Magazine|accessdate=March 5, 2010|archive-url=https://web.archive.org/web/20080408111410/http://www.vonmag-digital.com/vonmag/20080102/?pg=38|archive-date=April 8, 2008|url-status=dead}}{{Cite web|url=http://www.tmcnet.com/voip/1109/open-source-efforts-no-longer-an-obscure-sideshow-of-geeks.htm|title=Open Source Efforts No Longer an 'Obscure Sideshow of Geeks'|last=Bernier|first=Paula|date=November 2009|publisher=Internet Telephony Magazine|accessdate=March 5, 2010}}
