More Synthetic Vocal Bursts (Raw)

Synthetic vocal burst audio samples generated from a taxonomy of 202 vocal burst types across multiple text-to-audio and TTS models. Each sample is a short (3–10 second) non-speech vocalization — laughs, cries, gasps, sighs, growls, etc. — generated from text prompts describing the burst type, gender, and age group.

Models Used

Model	Type	Samples	Sample Rate	Notes
DramaBox (ResembleAI/Dramabox)	TTS DiT	2000	44.1 kHz	Original DramaBox DiT v1, cfg=2.5, stg=1.5, 30 steps
Stable Audio 3 Small SFX (cocktailpeanut/stable-audio-3-small-sfx)	Text-to-Audio	2000	44.1 kHz	SFX model, 8 steps, cfg_scale=1.0
MOSS SoundEffect v2 (OpenMOSS-Team/MOSS-SoundEffect-v2.0)	Text-to-Audio DiT 1.3B	781	48 kHz	100 steps, cfg_scale=4.0, bfloat16
