A computer-implemented method provides access to multimedia content, which include units of content that include audio components. Meta data for the units of content is formed to an association of key phrases detected in the audio components and the units. In some examples, forming the meta data includes determining a candidate set of key phrases associated with the unit of multimedia and searching for the presence of the candidate key phrases in the audio components. Forming the meta data then includes forming data representing the presence of key phrases in the audio components.
