A fully integrated speech solution for open source Asterisk, LumenVox Speech Engine Lite offers 500 vocabulary items per recognition. The Speech Tuner is included with this package.
LumenVox Speech Engine is a fully-integrated speech recognition solution for Asterisk. It is a speech recognition engine that performs recognition on audio data from any audio source, and allows for dynamic language, vocabulary lists, audio format, and logging capabilities. The LumenVox Speech Engine is directly and seamlessly integrated with the Asterisk platform and Dial Plan. Now application developers can easily build speech-enabled IVR’s by using the familiar Dial Plan scripting language or the LumenVox C language API.
The LumenVox Speech Engine is speaker and hardware independent, supports industry standards such as SRGS and Semantic Interpretation, and includes highly efficient barge-in and noise reduction technology for better performance in challenging environments. The engine relies on Grammars, which are a list of expected words or phrases that a caller might speak, to successfully recognize words.
