Searching Sound

Posted by michael on from the when-grep-isn't-enough dept.

Technology Review has one of their few stories that's not registration-required describing searching audio files for any specified set of sounds. All sorts of interesting applications become possible if you can turn analog audio into a digitally-useful product without massive human intervention.

    Lets home this doesn't make pointy head bosses think they can store customer information as a blob of speech data...

  2. Index or no index? by Psychic+Burrito · · Score: 3, Insightful
    There's quite a contradiction in this text. First they tell us that FastTalk doesn't uses an "index":

    The key to expediting the process was eliminating the need for transcription or indexing or both.

    Then on the second page, they say that some sort of pre-processing is needed:

    (...) the Fast-Talk approach ?processes the speech in such a way that you can later go back and search it very efficiently (...)

    So I see no revolution here... it's just about indexing the phonemes of a audio stream and then searching these, right?
