How the Speech Engine is Used
The LumenVox Speech Engine is a real-time, speaker-independent technology. Real-time means it can perform recognition on an audio stream immediately, and speaker independent means it does not require any special training to recognize a user?s voice. Most users of the Speech Engine use it in telephony applications, such as an IVR, but it can be used for any computerized command and control application, such as a voice dialer, order taker, or even to control simple actions on a PC. The Speech Engine is not dictation software, and it does not transcribe large audio files. It is used for applications where users speak short, discrete phrases.


How Speech Recognition Works
Speech engines use this process to figure out what a speaker said:

  • The engine loads a list of words to be recognized. This list of words is called a grammar.
  • Audio from a speaker is captured by a microphone or telephone. This audio is turned into a waveform, a mathematical representation of sound.
  • The engine looks at features - distinct characteristics of sound - derived from the waveform and compares them with its own acoustic model. The engine searches its acoustic space, using the grammar to guide this search.
  • It then determines which words in the grammar the audio most closely matches and returns a result.
