Mega-SSum

• A large-scale English sentence-wise speech summarization (Sen-SSum) dataset
  • Consists of 3.8M+ synthesized speech, transcription, summary triplets
  • Derived from the Gigaword dataset Rush+2015

Overview

• The dataset is divided into five splits: train/core/dev/eval/duc2003. (See below table)
  • We added a new evaluation split "test" for in-domain evaluation.
  • The train split is here: MegaSSum(train).

orig. data	split	#samples	#speakers	total dur. (hrs)	ave. dur. (sec)	CR* (%)
Gigaword	train	3,800,000	2,559	11,678.2	11.1	26.2
Gigaword	core	50,000	2,559	154.6	11.1	25.8
Gigaword	valid	1,000	96	3.0	10.7	25.1
Gigaword	test	4,000	80	12.5	11.2	24.1
DUC2003	duc2003	624	80	2.1	12.2	27.5

*CR (compression rate, %) = #words in summary / #words in transcription * 100. Lower is shorter.

Notes

• The core set is identical to the first 50k samples of the train split.
• The duc2003 split has four reference summaries for each speech. You can report the best score from 4 scores.
• Spoken sentences were generated using VITS Kim+2021 trained with LibriTTS-R Koizumi+2023.
• More details and some experiments on this dataset can be found here.
