🤖AI Summary
Facebook Research introduces the Latent Speech-Text Transformer (LST), which aggregates speech tokens into higher-level patches to improve computational efficiency and cross-modal alignment. The model achieves up to +6.5% absolute gain on speech HellaSwag benchmarks while maintaining text performance and reducing inference costs for ASR and TTS tasks.
Key Takeaways
- →LST addresses the computational inefficiency of auto-regressive speech-text models by aggregating speech tokens into latent patches.
- →The model achieves up to +6.5% absolute gain on speech HellaSwag benchmarks in compute-controlled training settings.
- →Performance gains scale with model size from 420M to 1.8B parameters and persist up to 7B parameters.
- →LST reduces effective autoregressive sequence length during ASR and TTS inference without degrading reconstruction quality.
- →The approach improves cross-modal knowledge transfer between speech and text modalities while maintaining text performance.
