Speech Recognition on arduino


  I have seen a library for doing speech recognition on arduino. Check the following link for seeing more information.


  1. Letter based recognition
  2. Small memory footprint
  3. Arduino Compatible
  4. No training required
  5. Fixed point arithmetic
  6. 30% - 40% accuracy if based on phonemes, up to 80% if based on words.
  7. Plugs directly into an analogRead() port
