For many people, speaking off the cuff to a large audience does not come easily. But without professional feedback, rehearsing speeches and presentations can be a tough process. A psychologist, a management scientist and an IT specialist have developed an online training tool that uses artificial intelligence to evaluate users' speaking skills and personal characteristics. The team has now established the start-up Retorio at the Technical University of Munich (TUM) to launch the software on the market. It's a scenario many people can relate to – standing all alone in front of an audience, clutching a microphone with clammy hands and finding one's mouth has gone dry. Whether it's a job interview or a wedding speech: for many people, the idea of speaking in public is associated with anxiety and uncertainty.

On the second level of artificial intelligence networked machines can develop new models and algorithms ad hoc. In HR this technology can improve the preselection of applicants. With this second stage of artificial intelligence we can tackle an imminent and important problem of employee selection today: Unconscious prejudices. The world is full of it, as well as the world of employee selection: As a rule, people prefer "themselves and their peers" to people who are socialized differently. Personal experience with certain behaviors of others also determines a person s judgement of others.

They can identify patterns in voice commands and react to them according to predefined algorithms. In HR these are employed when the initial contact with applicants is being made – often when it comes to answering standard questions about an advertised position. As chatbots they can support an ongoing interaction between recruiter and applicant during the recruiting process, in this case they quite simply increase the recruiters accessibility or the applicant. Second field of application: „Natural Language Processing" (NLP), this technology supports the scanning of letters of application to characterize the applicants range and use vocabulary and his "wording" in general. NLP can assist in writing job advertisements, by using a language which is exactly targeted towards the preferred group of applicants.
