Support System for Improving Speaking Skills in Job Interviews

Speaking in an appropriate manner is important in job interviews because the interviewer's judgment sometimes depends on the impression created by the speaker's eyes, facial expressions, and voice. It is therefore important to practice speaking for job interviews, but it is not easy to practice it alone. In this paper, we propose a support system for improving speaking skills in job interviews by taking into account the emphasis required in this particular type of presentation. We conducted an experiment to test whether the judgment of the system is consistent with human judgment. The correlation coefficients for intonation and emphasis were 0.68 and 0.42, respectively. However, those for the other features were below 0.2. This is because the current system assumes reading style speaking. In the future, we aim to collect spontaneous speeches in realistic job interview situations and use them as reference data.
