7. A method, comprising: a) obtaining in digital form by logic a choice of an interviewer language, and a choice of an interviewee language that is distinct from the interviewer language; b) obtaining, by an interviewer digital electronic system, a ranked list of topics, the topics expressed in the interviewer language, the ranking being determined at least in part upon a respective probability associated with each topic; c) displaying by logic the ranked list of topics on an interviewer graphics screen that is included in the interviewer digital electronic system; d) obtaining by logic in the interviewer digital electronic system from a user interface on the interviewer graphics screen a topic selection from the ranked list; e) obtaining by an interviewee digital electronic system a first interviewee information item expressed in the interviewee language, said first interviewee information item being associated with the topic selection; f) transmitting the first interviewee information item in audio form using interviewee sound equipment associated with the interviewee digital electronic system g) wherein the interviewee sound equipment includes a headset, adapted to transformation between a head-mount configuration and a broadcast configuration, the transformation involving apivoting of an ear cup of the headset relative to a headband of the headset, wherein the headset is adapted to automatically limiting transmission of audio information to amplitudes not exceeding a head-mount maximum amplitude in the head-mount form and to amplitudes not exceeding a broadcast maximum amplitude, larger than the head-mount maximum amplitude, in the broadcast form, and wherein the interviewee sound equipment in the step of transmitting the first interviewee information item is the headset in head-mount configuration, the method further comprising: h) transmitting a second interviewee information item expressed in the interviewee language in audio form using the headset in broadcast configuration.
