Sam does not comprehend letters in the alphabet spoken in sequence. In turn Sam computes sequentially spoken letters into words. Ex. Sam asked me to ask "what is the weather in ODC"? Sam did not compute me saying ODC and computed odissi. I slowed down my speech, spoke louder, spoke directly into the microphone and still no good. So I just thought I'd leave yoh this feedback. However greet concept on what you all are doing with the app, just a few bugs and could do more i think.
