Requirements elicitation interviews are the most commonly used technique for requirements elicitation. Through interviewing subject matter experts, facilitating deep discussions, and documenting findings, requirement analysts can uncover the true needs of the system to satisfy stakeholders’ needs. However, during these interviews, the analysts often have to divide their attention to asking the right questions, react appropriately to the stakeholder’s responses, and keep track of the information flow throughout the interview. This is a complicated process, during which analysts could make mistakes and miss important information. For these reasons, it could be useful for them to review their interviews to understand what information has been elicited and what has been missed, what they would need to ask as follow up, and what mistakes they have done during the process. To support these processes, we propose AnnoteREI, a tool that allows analysts to upload the recording of their interviews and create an editable transcript with speaker diarization. The tool offers many functionalities for different purposes: (1) students and novices can use it to identify and tag their mistakes, thus improving their skills by learning from their experience; (2) analysts can annotate any part of the transcript and tag it for later review. For example, they can label a section as a requirement or as a topic that requires more investigation, or a name mentioned by the interviewee as another stakeholder; and (3) researchers can use the tagging system to analyze and collect new data.
