I am trying to create a simple cloud deployed API function that will take an expression, e.g. "8*9" as a parameter and will return the spoken string "8 times 9". I can't seem to figure out the ToExpression, ToString? HoldForm? mechanism in conjunction with to make this work...
CloudDeploy[APIFunction["expression" -> "String", SpokenString[HoldForm[#expression]] &, "HTML"],Permissions -> "Public"]
