SpeechRole
Qwen3.5-Omni-Plus 123.5 Fading Speech role-playing agents talk in character across 98 roles. A model judge scores interaction ability, speech expressiveness and role fidelity from the generated speech.
Released with a 111k-conversation training set (SpeechRole-Data). Qwen reports scores above 100, so the scale is not a percentage.
In the authors’ words
Speech is essential for realistic role-playing, yet existing work on role-playing agents largely centers on text, leaving Speech Role-Playing Agents (SRPAs) underexplored and without systematic evaluation. We introduce SpeechRole, a unified framework for developing and assessing SRPAs. SpeechRole-Data contains 98 roles and 111k speech-to-speech conversations with rich timbre and prosodic variation, providing large-scale resources for training SRPAs. SpeechRole-Eval offers a multidimensional benchmark that directly evaluates generated speech, preserving paralinguistic cues and measuring interaction ability, speech expressiveness, and role-playing fidelity. Experiments show that end-to-end SRPAs such as GPT-4o Audio achieve strong fluency and naturalness, but remain limited in prosody consistency and emotion appropriateness. In contrast, current open-source end-to-end models exhibit substantial performance gaps across multiple evaluation dimensions. Cascaded and end-to-end systems achieve comparable results in interaction ability and role-playing fidelity, suggesting that these aspects are still largely influenced by the underlying text-based language models. We release all data, code, and evaluation tools at https://github.com/yuhui1038/SpeechRole.

Qwen3.5-Omni-Plus leads with 123.5
Best score per model as labs report them in their own cards. Labs pick their own settings, so these compare less cleanly than independent runs.

Scores over time
All the scores we have, one dot each, so a model tested at several settings appears more than once.
Labs headline it less often now, last in Mar 2026
