Diarization and Identity Attribution Compatibility in the Albayzin 2020 Challenge

Ignacio Viñals, Pablo Gimeno, Alfonso Ortega, Antonio Miguel, Eduardo Lleida

The current need to identify the speakers in a certain recording has evolved along time, requesting more and more information. While speaker recognition originally focused on determining whether a speaker talks in a certain audio with a single speaker, later diarization focused on differentiating speakers along the recording. The latest step is Identity Assignment (IA), which combines both of them, i.e., deciding whether a certain speaker is present in a given audio, as well as determining the periods of time when the speaker is active.

Our work presents and analyzes the ViVoLAB results for the Albayzin 2020 evaluation, focused on diarization and identity assignment. These challenges will be faced in the broadcast domain, with data coming from national Spanish TV Corporation RTVE. For this purpose we have developed a Bottom-Up diarization architecture based on the embedding-PLDA paradigm. On top of the diarization solution we have added an identity assignment block, based on the speaker verification approach.
