FastSLM: Hierarchical Temporal Abstraction for Efficient Long-Form Speech Adaptation

FastSLM introduces a Hierarchical Temporal Abstractor (HTA) that compresses long-form speech into just 1.67 tokens per second—a 97% reduction—while maintaining competitive performance on speech understanding benchmarks. This architecture solves a critical scaling bottleneck for multimodal AI models by preserving acoustic detail despite extreme compression, enabling efficient deployment of speech-capable language models.

Assessment of Personality Dimensions Across Situations in Dyadic Role-Play Scenarios

Researchers investigated how perceived personality traits vary across different conversational contexts, finding that acoustic and non-verbal features better predict personality dimensions than speaker embeddings. The study reveals that personality perception is situational rather than static, with stress levels significantly influencing how traits like neuroticism are perceived.

Acoustic Cue Alignment in Audio Language Models for Speech Emotion Recognition

Researchers demonstrate that instruction-following audio language models can effectively utilize explicit acoustic cues for speech emotion recognition, with aligned acoustic tokens improving performance on standard benchmarks while remaining grounded in the underlying audio signal.

In-Context Learning in Speech Language Models: Analyzing the Role of Acoustic Features, Linguistic Structure, and Induction Heads

Researchers investigate in-context learning (ICL) in speech language models, revealing that speaking rate significantly affects model performance and acoustic mimicry, while induction heads play a causal role identical to text-based ICL. The study bridges the gap between text and speech domains by analyzing how models learn from demonstrations in text-to-speech tasks.
