AI BriefingScaling Properties of Continuous Diffusion-Based Speech Language Models
Key point
A Continuous Diffusion-based speech model was shown to follow scaling laws while demonstrating potential for efficient inference.
Details
Existing discrete autoregressive (AR) speech models suffer from a bottleneck caused by the process of discretizing continuous speech. To address this, the efficiency of a Continuous Diffusion (CD)-based speech language model (SLM) was explored.
The research found that CD SLM follows Scaling Laws in both Validation Loss and the pJSD (phoneme Jensen-Shannon divergence) metric. The optimal token-to-parameter ratio of the model decreases as compute increases, suggesting that faster inference is possible.
Training at a scale of 16B parameters with tens of millions of hours of conversational data confirmed the following capabilities:
- Emotive speech generation
- Prosodic and Multi-speaker support
- Multilingual speech generation
However, maintaining long-form coherence remains a key challenge yet to be solved.
