VoiceFlow google custom code block for freeform text type input

Can anyone point me in the direction as to how I can create a custom code block that will allow me to save any word the user says. My problem is that the user is prompted to give me 2-3 words but they can be anything… The types on voiceflow are only date, time, and number. Is there a custom code block that will take capture block as input and save whatever is said in that capture block?
Thank you.

edit: it’s important to note that I do not know ahead of time how many words the user will say. I just want to save whatever it is that they say, does this make sense?

I solved the problem, if anyone has the same issue. If you just use number type, anything you say will be saved!
