我们带来 VoiceMem,为语音模型增加最后一个组件:灵魂,让它真正越来越懂你。VoiceMem 建立在「流式双脑」架构之上,提供精准、有情感、懂人格、低延迟且最便宜的记忆服务。本仓库将「永久保持全部开源」。
快速理解 VoiceMem:
注意: 播放前需要先取消静音。

git clone https://github.com/xzf-thu/VoiceMem.git
cd VoiceMem
# 安装记忆系统(含 ASR / 声纹 / 场景 / 情绪 / 本地 embedding 全套内置组件)
pip install voicemem
# 可选:用我们微调的 Qwen 回复模型
pip install "voicemem[slm]"
pip install -U huggingface_hub
hf download zhifeixie/VoiceMem_Default_Models_Env --local-dir ./models
…
可以把 VoiceMem 的流式接口看作一个持续处理音频的 VAD 接口。
下面这段:先显式存一条事实,再喂一段问句音频,看记忆是怎么在人还没说完时就查好的;最后照例走一次入库判断。
…
演示代码在仓库里(pip 装的包只有库本身),先确认已经克隆并进入仓库目录。
python web/run.py
然后访问:
http://localhost:8787
Demo 默认把终端输出(含 Python logging 和 Uvicorn 的日志)保存一份到
results/logs/voicemem-时间-PID.log,每行带时间戳和 stdout/stderr 标记。
启动时终端会打印实际路径。指定文件或临时关闭如下。
python web/run.py --log-file results/logs/debug.log
python web/run.py --no-file-log
回复模型的上下文由当前输入、本次会话尚未入库的对话和检索记忆组成。每轮对话先 进入内存 SessionBuffer;异步记忆写入完成并确认产生持久记忆后,对应 turn 从 SessionBuffer 移除。没有产生长期记忆的临时对话会保留到本次会话结束,不同 Memory Space 和不同 WebSocket 会话互相隔离。
播放期间的插话使用两阶段控制:VAD 首先暂停并保留音频队列;明确停止指令或稳定
ASR 文本确认后才清空队列并取消回复;附和、回声、无文字声音和单音节碎片会恢复
播放。候选静音回退和最长等待时间可分别通过 BARGE_REJECT_SILENCE_MS、
BARGE_CANDIDATE_TIMEOUT_MS 调整。
两种回复模式共用以 PCM 样本位置为基准的输出时间轴。浏览器 AudioWorklet 回报
实际渲染进度,打断时只把已经播放的回复写入 SessionBuffer。TTS 后端可选返回
TimedAudioChunk 提供文字对齐;普通 PCM 后端按分段音频长度和动态语速估算。
VoiceMem 是一个面向实时语音智能体的记忆系统。
VoiceMem 不把所有记忆放进同一个检索数据库,而是将记忆拆分成两个互相配合的部分:
整个流程都是流式的。
在用户仍然说话时,VoiceMem 会持续完成音频分段、语音转写、记忆提取,并把结构化信息写入记忆图中。
查询时,VoiceMem 会先路由,再排序,最后只把 Top-K 条记忆注入模型上下文,从而在保留相关信息的同时控制上下文长度。
我们通过三阶段 OPD 训练流程构建 ChatMem-400K:
同一套流程在人工编辑后形成 ChatMem-Bench,评测语音模型是否能够在长期沉淀中形成对用户的理解。
VoiceMem 家族开源模型包括 Qwen2.5-Omni、Qwen3-Omni 和 Step-Audio2-Mini。这些模型可以在对话时接受并理解 VoiceMem 提供的记忆信息。
你可以将 VoiceMem 接入自己的语音模型,用于构建带有长期记忆能力的实时语音智能体。
整体流程如下:
麦克风 → VoiceMem 监听语音并提前检索相关记忆 → 你的模型读取这些记忆并生成回答
export OPENAI_API_KEY=sk-...
# 仅在写入记忆时用于事实信息提取。
# 记忆检索完全在本地运行。
python examples/03_simple_agent_with_voicemem_memory.py
换成你自己的模型:把生成那一步换掉就行,记忆那半边一行都不用动。
def my_reply(text, memory_context): # 同步函数也可以,会自动丢线程
return my_model.generate(system=memory_context, user=text)
vm = VoiceMem(reply=my_reply)
VoiceMem 提供完整的微调代码,可用于训练自己的 VoiceMem Model Family Adapter。
默认训练配置与发布的 checkpoint-3318 使用的配置一致。
使用默认参数运行下面的命令,可以复现相同的 Adapter:
pip install ms-swift==4.5.2 bitsandbytes
python finetune/train.py --data data/train.jsonl
训练数据格式、GPU 显存要求,以及如何更换基础模型,请参阅 finetune/README.md。
评测流程完全开源,并且可以复现。
只需要一条命令即可运行 Benchmark:
export OPENAI_API_KEY=sk-...
# 建议先运行仓库中自带的小型示例,
# 确认环境和配置没有问题。
# 2 个对话,5 个问题。
python evaluation/run.py \
--dataset locomo \
--data evaluation/examples/locomo_sample.json
# 然后运行完整数据集。
python evaluation/run.py \
--dataset locomo \
--data data/locomo.json
示例结果:
LoCoMo: 10 conversations · 152 questions
Score: 139/152 = 91.4%
multi_hop 88.2%
temporal 85.7%
single_hop 95.1%
Median retrieval latency: 12 ms
Median retrieved memory: 298 tokens
在运行完整评测之前,可以加入 --inspect,检查数据集是否被正确解析。
这个模式不会调用模型,因此也不会产生 API 费用:
python evaluation/run.py \
--dataset locomo \
--data data/locomo.json \
--inspect
评测过程中,回答模型只会收到检索得到的记忆,不会收到原始对话历史。
如果直接把完整对话交给模型,Benchmark 测试的就会变成模型的阅读理解能力,而不是记忆系统本身的能力。
完整评测流程,以及添加新 Benchmark 的方法,请参阅 evaluation/README.md。添加一个新的 Benchmark 只需要增加一个文件并实现两个函数。

We introduce VoiceMem, adding the final component to voice models: a soul, so they truly come to understand you better over time. VoiceMem is built on a streaming dual-brain architecture and provides accurate, emotional, personality-aware, low-latency, and lowest-cost memory services. This repository will remain fully open source, permanently.
A quick overview of VoiceMem:
Note: Please unmute the video before playback. https://github.com/user-attachments/assets/0d919f8c-e9ba-4fdb-8078-b049e4b99a28
Prerequisite: Python 3.10+
git clone https://github.com/xzf-thu/VoiceMem.git
cd VoiceMem
# Install the memory system (bundles ASR / speaker ID / scene / emotion / local embedding)
pip install voicemem
# Optional: run our fine-tuned Qwen reply model
pip install "voicemem[slm]"
pip install -U huggingface_hub
hf download zhifeixie/VoiceMem_Default_Models_Env --local-dir ./models
…
Think of VoiceMem's streaming interface as a VAD interface that continuously processes audio.
The example below stores one fact explicitly, then feeds a question as audio to show how the memory is already retrieved before the speaker finishes. It ends, as always, with the ingest decision.
…
The demo lives in the repo (the pip package ships the library only) — make sure you have cloned it and are in the repo root.
python web/run.py
Then open:
http://localhost:8787
By default, the demo mirrors terminal output — including Python logging and
Uvicorn's own logs — to results/logs/voicemem-TIME-PID.log, one timestamped
line per record, tagged stdout or stderr. The resolved path is printed at
startup. To choose a path or disable file logging:
python web/run.py --log-file results/logs/debug.log
python web/run.py --no-file-log
Reply context combines the current input, turns from this session that are not yet represented by persistent memory, and retrieved memory. Each turn enters an in-memory SessionBuffer first. The asynchronous ingest completion callback removes it only after persistent memory is created. Buffers are isolated by Memory Space and WebSocket session.
Barge-in uses two stages during playback. VAD first pauses playback while
preserving the audio queue. An explicit stop command or stable ASR updates
confirm cancellation; backchannels, echo, non-text sounds, and isolated
syllables resume playback. BARGE_REJECT_SILENCE_MS and
BARGE_CANDIDATE_TIMEOUT_MS configure rejection timing.
Both reply modes share a PCM-sample media timeline. The browser AudioWorklet
reports actual rendered progress, so interrupted context contains only the
heard prefix. TTS providers may return TimedAudioChunk alignment metadata;
plain PCM providers use segment duration and an adaptive speech-rate fallback.
VoiceMem is a memory system built for real-time voice agents.
Instead of storing every type of memory in a single retrieval database, VoiceMem separates memory into two complementary parts:
The entire pipeline is streaming.
