LumenVox is a privately held speech recognition software company based in San Diego, California.
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.
[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][13][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.
