yeah.

My original idea  was to match whole words in ROM, rather that decode phonemes etc

Isn't it going to work better to match phonemes and then fuzzily compare phoneme strings after that?

    Hi Dean

    RRR

    OK. I have so far, used codec2 to to store phrases and vocab in a
    microcontroller... @ 3600 I have stored qute alot of talking in the
    1Mbyte of STM32 flash...

    WHat i'd need to do is sit down and look at which parts of the codec2
    frame would be best suited for initial candiate matches

    Kth nearest-neighbour or something.... IE distance in N
    dimensional space.
