StepAudio 2.5 Technical Report

StepAudio 2.5 is a unified audio-language model that combines understanding and generation in one system.

The report says task-tailored RLHF and specialized decoding improve ASR, TTS, and real-time spoken interaction.

It claims state-of-the-art results on standard benchmarks across speech recognition, synthesis, and dialogue.

If validated, it could reduce the need for separate speech models and simplify deployment.
