How to build a speaker identification system for recorded online meetings

Virtual meeting recordings have become an essential source of business intelligence but extracting actionable insights from them can be challenging due to the vast amounts of audio data involved. Speaker identification, using voice biometrics, offers a solution by distinguishing and identifying speakers in audio streams, thus enhancing the utility of recorded meetings. This tutorial provides a step-by-step guide to building a proof-of-concept speaker identification system for recorded meetings, utilizing tools such as the pyannote library for speaker diarization, SpeechBrain for speaker embedding extraction, and cosine similarity for matching speakers. The system aims to facilitate the creation of meeting summaries, action items, and personalized playback options by enabling efficient speaker identification and management. However, challenges such as resource management, optimizing similarity thresholds, and handling overlapping speech and background noise must be addressed to ensure system accuracy and efficiency. The tutorial underscores the increasing importance of audio data management in remote work settings and highlights the potential for integrating speaker identification into various applications to streamline meeting management and improve user interaction.
