The experiments presented in this work focus on radio news recordings involving around 11 speakers on average. Each of them is assigned automatically a role (e.g. anchorman or guest) without using any information related to their identity or the amount of time they talk. The results (obtained over 96 recordings for a total of around 19 hours) show that more than 85 percent of the recording time is correctly labeled in terms of role.
