Outline

SDBench is an open-source benchmark suite proposed to address the high variance in error rates of state-of-the-art speaker separation systems across multiple datasets representing diverse use cases and domains. It integrates 13 diverse datasets and provides tools for consistent and granular speaker separation performance analysis, enabling reproducible evaluations and easy integration of new systems. To demonstrate the effectiveness of SDBench, we build SpeakerKit, a system focused on inference efficiency based on Pyannote v3. We evaluate SpeakerKit's performance using SDBench and show that it is 9.6x faster than Pyannote v3 while achieving a similar error rate. We also benchmark six state-of-the-art systems, including Deepgram, AWS Transcribe, and the Pyannote AI API, to uncover the critical tradeoff between accuracy and speed.

Takeaways, Limitations

Takeaways:
Offering a diverse dataset and consistent evaluation tools, SDBench provides a standardized benchmark for comparing the performance of speaker separation systems.
SDBench allows you to perform efficient experiments (e.g., ablation studies) for system development and performance improvement.
By clarifying the tradeoff between accuracy and speed, it provides important information for system design and selection.
Contribute to the development of efficient and accurate speaker separation systems such as SpeakerKit.
Limitations:
The number and variety of datasets currently included can be further expanded.
Additional tools and guidelines may be required to integrate new systems.
It may be biased towards certain domains or use cases.
The number of systems included in the benchmark may be limited.
