This paper describes several methodologies for collecting conversational telephone speech (CTS) comparing their design, goals and yields. We trace the evolution of the Switchboard protocol including recent adaptations that have allowed for very cost-efficient data collection. We compare Switchboard to the CallHome and CallFriend protocols that have similarly produced CTS data for speech technologies research. Finally, we introduce the new "Fisher" protocol comparing its design and yield to the other protocols. We conclude with a summary of data resources that result from each of the protocols described herein and that are generally available.
