Question
In a nutshell: My voice-controlled home automation system was named ModernSteward (I'm stupid).
The confusing part is: when you are giving a command, there should be a keyword. The keyword is Melissa, so you can say "Melissa, turn the lights on".
Melissa is very catchy and since we have a lot of publicity with it, we are seeking for another name of the product. Obviously, "Melissa" is not OK, because melissa.com is registered.
We were thinking about something like MelissaHome.com
See the current website:
http://modernsteward.com
Answer
Melissa has too many potential pronunciations
Here are two, in IPA (https://en.wiktionary.org/wiki/Appendix:English_pronunciation):
/məˈlɪsə/
/meɪlisɑ/
Consider something that's a little more internationally pronounceable in order to avoid having multiple names for your product across the globe as you expand.
Definitely don't exceed three syllables, but two is probable a goal. "Siri" is two, "OK, Glass" is three, and "OK, Google" is four. You know what's easier to say quickly!
