Hi, (Cyrano)
I'm an iOS swift developer from melbourne (are you in melb too?), and I can make the speech recognition app for you. I already have most of the code done in swift; it uses openers to recognise one,two,three, to end, and displays the word on the screen (i got curious after reading your job and wanted to try it out). I would just need to add the mp3s (do you have these of should I make them?).
I have a number of apps on the app store which use audio, so adding the audio response should be quick.
Let me know if you're still looking for someone and we can chat about when you need the app etc..
Thanks,
Richie
