The paper introduces ScenA, a novel approach for generating multi-speaker audio scenes by conditioning a text-to-audio flow-matching foundation model on multiple reference voices and a natural language prompt. Unlike existing systems that rely on structured supervision like per-turn tags or speaker embeddings, ScenA operates directly on free-form descriptions of entire audio scenes. The model is pretrained on large-scale in-the-wild data, enabling it to produce ambient textures and realistic conversational dynamics beyond clean vocal sequences. This method aims to bridge the gap between synthetic and real-world audio environments.

- Flow-matching
- A generative modeling technique that learns to transform noise into data through a learned vector field.
- In-the-wild data
- Real-world data collected from diverse, unstructured environments, as opposed to controlled datasets.
- Text-to-audio
- AI models that generate audio (speech, music, or sound effects) from textual descriptions or prompts.
- Speaker embeddings
- Learned representations of speaker characteristics used to condition speech generation models.
- Ambient texture
- Background sounds or environmental noise that contribute to the realism of an audio scene.
