The LumenVox Speech Engine is an accurate, standards-based speech recognizer that supports multiple languages and can perform speech recognition on audio data from any audio source. On Linux or Windows, the speaker and hardware independent Speech Engine powers speech solutions and platforms deployed in Enterprise and SMB environments worldwide.

It also provides speech application developers with an efficient development and runtime platform, allowing for dynamic language, grammar, audio format, and logging capabilities to customize every step of their application. Grammars are entered as a simple list of words or pronunciations, or in the industry standard Speech Recognition Grammar Specification (SRGS).
