A system is configured to obtain a first voice request, from a client, to access a voice processing system that processes voice communications received from clients; determine a first pace at which terms, associated with the first voice request, are spoken by a user of the client; determine a second pace, associated with the user, based on terms, associated with other voice requests, spoken by the user and users of the clients prior to receiving the first voice request by using a weighted average of the pace associated with the user of the client and a pace associated with the users of the clients other than the client; compare the first pace to the second pace; determine a third pace based on the comparison; and send, to the client, a voice response to be outputted at the third pace.
