Cannot bring up my talk to text icon on my Samsung Galaxy s7 Edge

[Android Central Question]

From reading below for a fix. I do have the Google app on my phone. Next to my text all I see is the plus mark (+). When I hold it down all I get are emoji's. I cannot find the microphone icon any where. I went into my settings - General, language and input, I have the Samsung default keyboard. Spoken results is turned on. What else can I do?
