Abstract: A method and apparatus for indexing one or more audio signals using a speech to text engine and a phoneme detection engine, and generating a combined lattice comprising a text part and a phoneme part. A word to be searched is searched for in the text part, and if not found, or is found with low certainty is divided into phonemes and searched for in the phoneme parts of the lattice.

Abstract: A method and apparatus for revealing business or organizational aspects of an organization from interactions, broadcasts or other sources.

Abstract: A method and apparatus for revealing business or organizational aspects of an organization in audio signals captured from interactions, broadcasts or other sources. The method and apparatus activate an efficient process to detect events within the audio signal, and then activate a more resource-consuming additional process around the detected events, thus enhancing efficiency of the process. The detected events and the output of the additional process are analyzed by an analysis process to reveal business aspects, terms, or other events in the audio signal. The analysis results, and possibly the events and output of the additional processing are optionally presented to a user.
