#005 IT 热点速递 | Chatterbox TTS Turbo, Sopro TTS, 嵌入式框架 Embassy

Fri, 09 Jan 2026 10:37:59 +0800

Hi, 各位读者朋友，欢迎回到 FS IT’s English Channel. 这是我们的第 5 期内容。

本期我们来看 2 个 TTS 项目介绍和一个基于 Rust 的嵌入式框架。

Chatterbox TTS Turbo

Made with ♥️ by RESEMBLE.AI.

github 地址：https://github.com/resemble-ai/chatterbox HF 地址: https://huggingface.co/spaces/ResembleAI/chatterbox-turbo-demo (model-scope 上也可以找到，方便下载 model)

关注到这个是因为前段时间（所以这个也没有“速递”了 :)）看到的 tweet:

“ Source Text

This is the DeepSeek moment for Voice AI.

Chatterbox Turbo is an MIT-licensed voice model that beats ElevenLabs Turbo & Cartesia Sonic 3!

<150ms time-to-first-sound
Voice cloning from just 5-second audio
Paralinguistic tags for real human expression

100% open-source.

这里的 Paralinguistic, 词典解释是 relating to communication through ways other than words, for example tone of voice, expressions on your face and actions，就是用来控制语调、语速、发声质量等的标记，如 [laugh], [cough].

这里介绍的是新发的 Turbo model，参数量 350M, 仅支持 English. Chatterbox-TTS 其实已经发布很久了（至少8个月），看下 Github 的描述：

“ Source Text

Chatterbox is a family of three state-of-the-art, open-source text-to-speech models by Resemble AI.

We are excited to introduce Chatterbox-Turbo, our most efficient model yet. Built on a streamlined 350M parameter architecture, Turbo delivers high-quality speech with less compute and VRAM than our previous models. We have also distilled the speech-token-to-mel decoder, previously a bottleneck, reducing generation from 10 steps to just one, while retaining high-fidelity audio output.

单词 retain, To retain something means to continue to have that thing, 保留、保持，比较正式的一个词。看下面几个例句：

retain 例句

The interior of the shop still retains a nineteenth-century atmosphere.

这家商店的内部装修仍然保留着19世纪的风格。
If left covered in a warm place, this rice will retain its heat for a good hour.

如果加盖放在暖和的地方，这些米饭可以保温足足一个小时。

我自己跑了下这个 model, 模型下载下来一共 3.8G; 在我的 3060 12G 上可以跑起来，速度也还可以接受。需要一个 clone 音源，我拿之前 kokoro 的音频作为音源，跑了下结果，可以听下对比：

Kokoro Output:

Your browser does not support the audio element.

ChatterTTS Turbo

Your browser does not support the audio element.

这个例子来看，Chatterbox Turbo 效果不太好——主要体现在音质比较差。或许还是拿 TTS 的音频去做 clone 音源的问题。我之前测试它的 Demo，感觉它的结果更自然点，特别是配合上 paralinguistic tag, 不过在我这个设置下，确实没啥优势。

Sopro TTS

葡萄牙的一个个人开发者作品。Github 地址 https://github.com/samuel-vitorino/sopro

“ Source Text

Sopro (from the Portuguese word for “breath/blow”) is a lightweight English text-to-speech model I trained as a side project. Sopro is composed of dilated convs (à la WaveNet) and lightweight cross-attention layers, instead of the common Transformer architecture. Even though Sopro is not SOTA across most voices and situations, I still think it’s a cool project made with a very low budget (trained on a single L40S GPU), and it can be improved with better data.

Some of the main features are:

169M parameters
Streaming
Zero-shot voice cloning
0.25 RTF on CPU (measured on an M3 base model), meaning it generates 30 seconds of audio in 7.5 seconds
3-12 seconds of reference audio for voice cloning

这个有点奇怪，听 demo 音频显然音质是很差的，但是 Hacker News 上倒是挺多赞的。所以有一条评论是质疑的：

“ Source Text

I don’t understand the comments here at all. I played the audio and it sounds absolutely horrible, far worse than computer voices sounded fifteen years ago. Not even the most feeble minded person would mistake that as a human. Am I not hearing the same thing everyone else is hearing? It sounds straight up corrupted to me. Tested in different browsers, no difference.

feeble

If you describe someone or something as feeble, you mean that they are weak.

feeble 例句

He’s a bit feeble nowadays.
a feeble old man.

feeble minded 字面指心智虚弱，也即愚蠢、智力极低的，是一个有点冒犯性的词语。

mistake A as/for B

If you mistake A as B, you wrongly believe that A is B, or think that A and B are the same thing.

常见变体：mistake A for B（更常用、更自然）

mistake A as/for B 例句

I mistook him as a tourist because of his accent.
From a distance, the object could easily be mistaken as a person.
She was mistaken for someone else at the conference.

也许 Hacker News 上也有软文推广吧。不过这个项目确实还挺有意思的——对机器资源有限又想要训练一个 TTS 的朋友，可以参考看看。

Embassy

项目地址：https://github.com/embassy-rs/embassy

一个用来写嵌入式程序的框架。对此方向不是特别了解，ChatGPT 介绍背景如下：

Embassy programs are compiled into firmware and flashed directly onto microcontrollers. There is no operating system — the code runs on bare metal, and Embassy provides its own async executor to schedule tasks after power-on.

基于 Rust + Async 来开发。

“ Source Text

The Rust programming language is blazingly fast and memory-efficient, with no runtime, garbage collector, or OS. It catches a wide variety of bugs at compile time, thanks to its full memory- and thread-safety, and expressive type system.

Rust’s async/await allows for unprecedentedly easy and efficient multitasking in embedded systems. Tasks get transformed at compile time into state machines that get run cooperatively. It requires no dynamic memory allocation and runs on a single stack, so no per-task stack size tuning is required. It obsoletes the need for a traditional RTOS with kernel context switching, and is faster and smaller than one!

blazingly: blazingly is used to emphasize that something is extremely intense or impressive, especially in informal or technical contexts.

unprecedentedly: Unprecedentedly is used to say that something happens in a way or to an extent that has never happened before. 前所未有的

obsolete

/ˌɑːbsəˈliːt/，注意是 iː.

传统词典里只有形容词用法，Something that is obsolete is no longer needed because something better has been invented. 这里是动词，To obsolete something means to cause it to become outdated or unnecessary.

obsolete 例句

Smartphones obsoleted standalone GPS devices.
The system was obsoleted by a more efficient alternative.
With technological changes many traditional skills have become obsolete.
So much equipment becomes obsolete almost as soon as it’s made.

这么多设备几乎一生产出来就要被淘汰。

有相关需求的朋友可以看看这个，依赖简单，看起来编译好刷到固件里就可以用了。

End

好啦，这就是本期的内容啦。我们在继续缩减投入量，所以现在就不放 TTS 音频了。

但是更新还是会继续的，所以 stay tuned for updates!

#004 IT 热点速递 | Mockito TimvdLippe: Stepping down as maintainer after 10 years

Mon, 29 Dec 2025 22:37:59 +0800

Hi, 各位读者朋友，欢迎回到 FS IT’s English Channel. 这是我们的第 4 期内容。

今天我们摘录部分 Mockito (“The most popular mocking framework for Java”) 核心维护者 TimvdLippe 宣布卸任的原文，学习下当我们要选择离开某个职位时，该如何贴切表达吧 :)

source：Stepping down as maintainer after 10 years

Stepping down as maintainer after 10 years

首先我们看下短语

Step down

If someone steps down, they leave an important job or position, especially one of responsibility.

“辞去某个职位，卸任”。常用于主动让位、平稳交接的语境。反过来，step up 就是指上任、承担更重要职责。

step down 后面常用介词 as 或者 from，as 后面常接具体的身份/角色；from 后面除了接职位，还可以是组织等。

Step down 例句

The CEO stepped down after ten years in charge.
She announced that she would step down as project lead at the end of March.
He stepped down from leadership after the transition.
After the scandal, the minister was forced to step down from office. (scandal, 丑闻)

接下来看正文，首先是离任的声明。

“ Source Text

In March 2026, I will be Mockito maintainer for 10 years (nearly a third of my whole life). Looking ahead, I decided that a decade milestone is a good moment to pass on maintainership to other folks. In the coming months until March, I will spend time ensuring a smooth transition in maintainership.

In this issue I list several considerations why I made the decision. Communication and discussion of plans for future maintainership will be somewhere else, most likely in a separate GitHub issue. Stay tuned for that.

关注 2 个短语。

pass on A to B

If someone passes on something to another person, they give it to them so that the other person can take responsibility for it or continue with it.

“交接”。另一个常用的表交接的词是 hand over；要做对比的话，可以认为 pass on A to B 强调传承这种略虚的东西; hand over 偏重具体的事情或者流程本身。看下面的例句：

Pass on A to B 例句

After a decade, he chose to pass on the torch to the next maintainers.
She felt it was time to pass on her knowledge to the next generation.
The maintainer is preparing to hand over the codebase.
The founder handed over control of the company to a new CEO.

最后，注意 “pass on” 本身有“拒绝”的含义，如 I’ll pass on the offer (我不考虑这个提议).

Stay tuned

If you say stay tuned, you are telling people to continue watching, listening, or paying attention because more information will be given later.

“敬请关注”，应用非常广泛的词语。看下面的例句是否很熟悉：

Stay tuned 例句

More details will be announced soon — stay tuned.
We’re working on the next release. Stay tuned for updates.

Energy drain because of JVM agent change

上面 2 段 Tim 说了决定，接下来就将展开 3 点理由。限于篇幅，我们就摘第一点来看。

在看第一点前，先补充下背景（据 ChatGPT）： Mockito 主要用 ByteBuddy 库修改底层字节码来实现 Mock；但是 JVM 22 出于安全考量限制了普通包(artifact)的字节码修改能力；要想实现之前的类似能力，必须得编译成 Agent 类型的包。但 JVM 对 Agent 类型的支持尚不足够完善，配套工具链也没有完全建立。也就是说，Mockito 要适配这种变更，不得不去踩坑！

基于此背景，我们先看第一点的前半部分：

“ Source Text

As you might know, Mockito 5 shipped a breaking change where its main artifact is now an agent. That’s because starting JVM 22, the previous so-called “dynamic attachment of agents” is put behind a flag. This change makes sense from a security point-of-view and I support it.

However, the way this was put forward to Mockito maintainers was energy draining to say the least. Mockito is probably the biggest user of such an agent and is often looked at for inspiration by other projects. As such, Mockito often pioneers on supporting JVM features, built on a solid foundation with ByteBuddy. Modules was such a feature that took months of hard work by Rafael to figure out, including providing feedback to JVM maintainers.

Unfortunately such a collaborative way of working was not the case when discussing agents. To me, it felt like the feature was presented as a done deal because of security. While dynamic attachment is problematic in many ways, no alternative solutions were proposed. That’s okay, as Mockito pioneers on these solutions, yet in this case I felt we were left alone.

先看单词

drain

非常重要的一个单词。动词形式有排空、使耗尽的意思；名词形式有下水道、排水管、消耗的含义。这段里都是和 energy 搭配，用了 2 个形式：

Energy drain: 做名词，消耗
(be) energy draining，现在分词做形容词

实际上 energy drain 或者 energy-draining 都是一个固定搭配，An energy drain is something that makes you feel very tired, either physically or mentally, because it requires a lot of effort or causes stress.

Energy drain / Energy-draining 例句

Constant meetings have become a real energy drain.

没完没了的会议成了真正的精力消耗。
Maintaining the project alone was an energy drain over time.

长期独自维护这个项目逐渐消耗了他的精力。
The process was slow and energy-draining.
Long-term maintainership can be energy-draining.

长期的维护工作可能非常耗费精力。

再看下面这个句子：

the way this was put forward to Mockito maintainers was energy draining to say the least.

句子核心是 the way was energy-draining, this was put forward to Mockito maintainers 是后置定语从句，修饰 the way, 省略了关系代词 that/in which.

其中两个重点短语：

put forward

提出、提议. 常见于技术提案、标准讨论等正式场景。 If someone puts forward an idea, suggestion, or plan, they formally suggest it for consideration or discussion.

put forward 例句

She put forward a proposal to change the review process
Several options were put forward during the discussion.

to say the least

固定短语，“至少可以说”、“往轻了说”（实际更严重）。在这句话里是一个表语气的插入语，一般放在句子末尾，正式书面语境下前面会加一个 dash 或者逗号与主句隔开。 You use to say the least to emphasize that a statement is an understatement, and that the real situation is stronger or more extreme than you have said.

to say the least 例句

The last few months have been difficult, to say the least.

最近几个月很困难——实际情况更糟。
Running the project alone was demanding, to say the least.

独自运行这个项目非常吃力——远不止如此。

最后列出其他比较重要的短语：

so-called: 所谓的
make sense: 有道理（高频口语）
pioneer: n, 先锋；v, 当开拓者
a done deal: 已经板上钉钉的事 (比较口语化)。Once the contract is signed, the promotion is a done deal. 合同一签，升职就板上钉钉了。
yet (in this case…): 但是。转折显得克制但带失望——“按理说不该这样”；对比: but, 转折强度普通、中性；however, 正式、书面，偏理性。

继续看着点的后半段：

“ Source Text

My personal take is that folks involved with the change severely underestimated the societal impact that it had. The fact that proper build support is non-existent to this day shows that agents are not a priority. That’s okay if it isn’t a priority, but when it was communicated with Mockito I perceived it as “Mockito is holding the JVM ecosystem back by using dynamic attachment, please switch immediately and figure it out on your own”.

Here, the fact that I (and others) are volunteers doing their best for the project, is important to understand the societal impact. When you put individuals under pressure, who do this work in their own time out of goodwill, things crumble. It’s commonly joked about with XKCD’s on the fact that the whole open source world relies on a couple of individuals. That couldn’t be more true in this situation, where the collaborative system collapses when too much pressure is put on individual folks.

This saga planted the seed to reconsider my position as maintainer.

这里我们先看 2 个重点词汇/短语：

hold back

这里是“阻碍，拖慢”。If something holds someone back, it prevents them from making progress or developing. 还有一个意思是“克制自己不去做某事”。

hold back 例句

I don’t want my availability to hold the project back.
Outdated processes are holding the team back.
She held back her anger during the meeting.

crumble

碎裂、崩溃、瓦解。If something crumbles, it breaks into small pieces, or begins to fall apart. If a system, organization, or feeling crumbles, it suddenly or gradually fails or loses its strength.

crumble 例句

The old stone wall began to crumble.
The biscuit crumbled in his hand. (biscuit /ˈbɪskɪt/, 饼干)
Her confidence crumbled after the setback. (setback, 挫折)
The system began to crumble under pressure.

再看最后一句话：

This saga planted the seed to reconsider my position as maintainer.

比较漂亮。学习 2 个点：

saga /ˈsɑːɡə/

原意是“长篇史诗”，这里指“持续很久、反复拉扯、让人 energy-draining 的一整套事情”。 A saga is a long and complicated series of events or experiences.

saga 例句

After all the delays, the saga of getting the project approved finally ended.
The saga of our move across the country took months to resolve.

我们跨州搬迁的“史诗级”折腾，耗时数月才尘埃落定。

plant the seed (of/for/to) ...

种下…的种子。中文里也很常用，在英语里也是一个地道的表达。You plant the seed when you start an idea that may grow in the future.

plant the seed (of/for/to) 例句

Her question about sustainability planted the seed of doubt in the team’s mind about the current design. (sustainability, 可持续性)
The workshop didn’t propose a solution — it simply planted the seed to rethink how we measure success.
Early exposure to open-source projects can plant the seed of curiosity that grows into a lifelong career.

最后简单列出其他重点词汇：

societal: /səˈsaɪətl/ 社会的。与 social 做对比，societal 强调社会“制度”的，social 更多指“人际、社交”层面的。
perceived: 察觉到的，强调主管感受。扩展词: perception(感知), perceptron(感知器).
out of goodwill: 出于善意
XKCD: 指 https://xkcd.com，一个网络漫画网站。这里的 joke 应该就是 https://xkcd.com/2347/.

Summing it up

最后我们摘录 Tim 总结部分的一段如下：

“ Source Text

While these points had impact on me as maintainer, my hypothesis is that it doesn’t apply to others in the same way. I know others are eager to work on Kotlin support for example. That’s why I concluded that a decade is enough time to have helped Mockito forward. Now it’s time for somebody else to take over, as I believe that’s in the best interest of Mockito as a project. Because ultimately that’s why I chose to become maintainer in the first place: I believed that with my work, I could improve Mockito for millions of software engineers.

就重点说 1 个短语：

in the best interest of ...

对 … 最有利，符合 … 的最佳利益。If something is done in the best interest of a person or group, it is done to benefit them most effectively

in the best interest of ... 例句

The doctor made the decision in the best interest of the patient’s health.
We postponed the release in the best interest of product quality and user safety.
The court ruled that placing the child with her grandmother was in the best interest of the child.

再来翻译最后一句话：Because ultimately that’s why I chose to become maintainer in the first place: I believed that with my work, I could improve Mockito for millions of software engineers.

ChatGPT 翻译：因为归根结底，这就是我当初选择成为维护者的原因：我相信，通过我的工作，我能够让数百万软件工程师受益，并改善 Mockito 项目。

抉择时刻，记得回望初心啊。

#003 IT 热点速递 | 基于 Yaml 的简历渲染器 RenderCV, MicroQuickJS and 企业网络下实现稳定视频流的极简方法

Tue, 23 Dec 2025 14:07:59 +0800

Hi, 各位朋友，这是本频道的第 3 期内容。我们开启新的系列—— IT 热点速递。本文选取了 GitHub trending 和 Hacker News 上的热门、有一定普适性的内容，希望对你的工作有所帮助。

1. RenderCV: resume generator for academics and engineers

source: https://github.com/rendercv/rendercv

resume 这里是“简历”的含义，注意发音是 /‘rɛzjuːmeɪ/，近似：REZ-you-may. 它还有“继续”的含义，此时发音 /rɪˈzuːm/ 近似：ri-ZOOM. 为了区分，有时做“简历”意时可以写成 résumé.

简历, 在北美常用 resume 这个单词，而英式、欧洲用 CV (curriculum vitae).

“ Source Text

Write your CV or resume as YAML, then run RenderCV by rendercv render John_Doe_CV.yaml, and get a PDF with perfect typography. No template wrestling. No broken layouts. Consistent spacing, every time. With RenderCV, you can:

Version-control your CV — it’s just text.
Focus on content — don’t worry about the formatting.
Get perfect typography — pixel-perfect alignment and spacing, handled for you.

typography: 排版

wrestling: 有“摔跤”的含义，here means struggling with something difficult, awkward, or frustrating, rather than the sport - “较劲/折磨”。注意发音 /ˈre-sliŋ/, t is silent.

wrestling 例句

I spent hours wrestling with the configuration files.
No more wrestling with CSS layouts.

2. Fabrice Bellard Releases MicroQuickJS

source: https://news.ycombinator.com/item?id=46367224

今日 Hack News top1.

“ Source Text

MicroQuickJS (aka. MQuickJS) is a Javascript engine targeted at embedded systems. It compiles and runs Javascript programs with as low as 10 kB of RAM. The whole engine requires about 100 kB of ROM (ARM Thumb-2 code) including the C library. The speed is comparable to QuickJS.

引起如此热议的原因有 2 个: JS related; Fabrice Bellard (the developer) related.

“ Source Text

(comment 1) This engine restricts JS in all of the ways I wished I could restrict the language back when I was working on JSC. You can’t restrict JS that way on the web because of compatibility. But I totally buy that restricting it this way for embedded systems will result in something that sparks joy.

(comment 2) Well, as Jeff Atwood famously said, “any application that can be written in JavaScript, will eventually be written in JavaScript”. I guess that applies to embedded systems too.

buy

注意这个 buy, 非常 native 的用法。 If you buy an idea or explanation, you believe it, accept it, or find it convincing, 类似中文的 “买账”.

buy (≈ believe) 常见用法

I buy that.
Do you really buy this explanation?
I don’t buy the idea that complexity is unavoidable.
At first I was skeptical, but now I buy it. (skeptical, 怀疑的)

“ Source Text

(comment 1) Fabrice Bellard is widely considered one of the most productive and versatile programmers alive.

(comment 2) Fabrice is an absolute legend. Most people would be content with just making QEMU, but this guy makes TinyC and FFmpeg and QuickJS and MicroQuickJS and a bunch of other huge projects. I am envious that I will never anywhere near his level of productivity.

(comment 3) For all the praise he gets here, few seem interested in his methods: writing complete programs, based on robust computer science, with minimal dependencies and tooling.

(comment 4) When I first read the source for his original QuickJS implementation I was amazed to discover he created the entirety of JavaScript in a single xxx thousand line C file (more or less). That was a sort of defining moment in my personal coding; a lot of my websites and apps are now single file source wherever possible/practical.

versatile: “多面手”,常用来形容人或者工具。

be content with: If you are content with something, you are satisfied with it and do not want more or anything different. “满意，知足”。

envious: adj 嫉妒的(动词 envy)

a sort of: If you say a sort of something, you mean a type or kind of it, or something that is like it but not exactly the same. 口语里常用。

A sort of 例句

Quill acts as a sort of rich-text playground for web developers.
The configuration file is a sort of blueprint for building the system.

3. We replaced H.264 streaming with JPEG screenshots (and it worked better)

source: https://news.ycombinator.com/item?id=46367475

基于 ChatGPT 摘要，我再重新组织了下重点，希望对你有所启发。

The initial implementation used a modern video pipeline: hardware-accelerated H.264 encoding, WebSockets, and browser-side decoding. On paper, it delivered smooth, high-frame-rate video. In practice, it frequently failed. Many corporate networks aggressively restrict traffic, deprioritize UDP, or block WebRTC-related protocols altogether, leaving only HTTPS traffic on port 443 reliably usable.

企业网络上对网络协议有限制，阻碍了新技术的应用。On paper, In practice 适合用在理想和实际的对比中；aggressively 激进地；deprioritize 使低优先.

In the end, the most reliable solution turned out to be the simplest one: periodically serving JPEG screenshots over plain HTTPS. Despite being more than a decade old, this approach worked consistently across locked-down enterprise networks, degraded gracefully under poor conditions, and required far less infrastructure and client-side complexity.

最简单的方法成为了最可靠的方法。turned out to be 适合用在结论处；periodically 定时地；locked-down, 封锁的, 高度受限的。

The takeaway is not that modern streaming technologies are bad, but that real-world constraints matter more than theoretical elegance. Sometimes, shipping a robust product means choosing boring, well-understood tools — and accepting that older technology can still be the right answer.

方法是为问题服务的。The takeaway is 适合做经验总结；elegance 优雅；ship a product 固定用法。
