Multimodal Speaker Diarization for Long-Form Video Scripts

iQIYI’s multimodal speaker diarization system splits long‑form video using subtitle timestamps and scene detection, extracts voiceprints with a custom model, hierarchically clusters them, and applies an Activate Speaker Detection algorithm combined with face‑recognition to assign speakers, achieving around 90 % precision and recall and boosting downstream tasks such as summarization, translation, and dubbing.

iQIYI Multi-AZ Unified Scheduling Architecture for Big Data

iQIYI’s Multi‑AZ unified scheduling architecture combines a unified storage layer (QBFS), an abstracted compute scheduler (QBCS), and a federated metadata service (Waggle Dance) to seamlessly route data and jobs across availability zones, cut storage costs up to 65 %, reduce overall big‑data workload expenses by more than 35 %, and lay the groundwork for future hybrid‑cloud expansion.
