Hands-free devices work well with the family radios (FRS), BUT/BUT/BUT...
There's a time delay before the voice activation (VOX) kicks in. We find it helpful to start every sentence with 1...2...3...stuff and more stuff. The count cadence at least lets the listener know they heard the whole stuff, or how much they may have missed.
Also, these are simplex radios, if that matters, so your radio procedure would need to take that into account.
Eartec offers some full duplex systems; maybe others. Don't know about frequency usage in various jurisdictions.
