IVR does not understand Facebook and Instagram words

[victorssantos]

I'm setting up an IVR to ask a simple question: "How did you find us?"

I do not want to say "Press 1 for this, 2 for that, 3,4,5,6, etc" so I added some options like Facebook, Instagram, Google, Bing, Search Engine, etc.

If I say "Google", it works, "Search Engine" works, and "Bing" works, but it is not working for the options "Facebook" and "Instagram". I tried speaking in many different ways and asked different people to try but does not detect both words at all.

Any suggestion?
