llama.cpp b12061：mtmd 支持 PocketTTS 预定义音色
原标题：b12061
AI 摘要
llama.cpp 发布 b12061 版本，为 mtmd 模块新增对 Kyutai pocket-tts 预定义音色的支持：转换器将各音色对应的 backbone KV 状态还原为 prompt embeddings 并存入 mmproj，无需 voice cloning 即可选用音色。服务端在 /props 中列出可用音色，未知音色返回 400，未指定音色时默认使用第一个预定义音色。该更新让 llama.cpp 的 TTS 能力覆盖更多轻量语音模型，并改善 API 行为一致性。
