ST iphone Widget to create an a TTS on Echo

Is there anyway to produce a custom TTS phrase for Echo to say when I initiate a routine or activate a ST widget from my iphone? I know that the AskAlexa and Echosistant Skills are both able to produce a TTS responses, but they are vary bulky setups for just this simple action. Also, I’ve read that there might be an issue with alexa not being able to just wake-up and say something from standby unless you use the wake-up word?
