DuplexDrama
We present DuplexDrama, the first synthesized spoken dialogue dataset that combines four dimensions not simultaneously available in any prior corpus:
We have produced more than 2,000 hours of audio data with a 64-voice timbre pool spanning 13 personas and 5 age buckets; 3.8% of all turns carry at least one full-duplex behavior. This data has been validated through internal full-duplex model training. We will release a curated subset of 6,400 bilingual dialogues (800 hours, Chinese ∼500 h + English ∼300 h) to advance full-duplex spoken dialogue model research. An asset bank supplies 600 environment audios (across 7 scene categories) and 2,203 sound event audios (52 categories), both injected into the dialogue track through a match strategy. Data samples are available on this page; LLM-judge evaluation prompts will be released with the dataset.
The three full-duplex tiles are each tag family's share across all ∼362k turns (Table 2). The corpus-level 3.8% in the Abstract is the union of all three families at the utterance level.
Synthetic audio: all voices are generated. The audio in this demo export does not carry an AudioSeal watermark.
Note: these are excerpts, not complete dialogues — cut this way so the dataset's characteristics are audible at a glance rather than buried in a several-minute recording. Expand "Transcript" to read every turn in the excerpt; the event turn is highlighted in amber.
