15. A computer program product embedded in a computer usable non-transitory medium, in a database management system, tangibly embodying a program of instructions executable by the computer to perform a computer-based method for speech to text conversion preprocessing of a presentation with a speech audio, comprising: capturing a presentation speech audio input to be converted into text; preprocessing the presentation speech audio input prior to its speech to text conversion by temporally associating the speech audio input with at least one supporting text source from the same presentation containing common keywords; and creating an optimized and prioritized keyword positional index metadata set for inputting into a speech to text conversion processor.
