Show HN: Lipdub Videos to Any Language https://ift.tt/DZH0fL9

Show HN: Lipdub Videos to Any Language TLDR: Translate, dub, and lip-sync videos into 29+ languages. Here's an example: https://ift.tt/MupUazj... I was creating a few educational math videos for kids in Latin America last summer, and I noticed they weren't easily following subtitles. I wanted to make the video content more engaging for them, but I'm still a ways away from Spanish proficiency. Went down the rabbit hole of audio + video AI models... and now we have the initial version of Viva Labs! Given a video, we first translate the audio to the target language using a pipeline of ASR models, translation APIs, & LLMs - users can edit translations to fix any errors. Then, we dub the audio with similar voices or voice clones. Finally, we sync the speakers lip movements to match the dubbed audio. Our early users have surprised us with some of the common use cases like dubbing online course content, product explainers + marketing promos, podcasts, and international newscasts Still a lot of work to do to create full immersion. The following areas of technical exploration we're pursuing: 1) matching the output audio's tone, prosody, & emotion with that of the input voice using speech to speech models, 2) training lip sync models with more robust lip sync for extreme poses and occluding objects, 3) using LLMs to produce translations that are more colloquial and more closely match the pacing of original audio. Here's a sample of Mira Murati's GPT4o announcement lip dubbed to Russian: https://ift.tt/MupUazj... Looking forward to seeing what videos you dub! You can dub 3 minutes of video for free at app.vivalabs.ai or you can ask our twitter bot x.com/VivaDubs to audio dub a video on twitter https://app.vivalabs.ai June 18, 2024 at 01:31AM

Show HN: b2v.xyz – Protection against impersonation attacks https://ift.tt/FdKjISU

Show HN: b2v.xyz – Protection against impersonation attacks Hi HN, I’m the founder of https://b2v.xyz , a service that protects organizations against impersonation attacks. The problem I’m trying to solve stems from the following observation: while end-user authentication methods are becoming more advanced as cybersecurity evolves, organizations aren't experiencing the same improvements when we reverse the roles, i.e. when organizations authenticate themselves to their users. This imbalance leaves a gap in secure communications that B2V aims to close. Bad actors have countless ways to pose as trusted entities — through phishing, smishing, vishing, and more. These catchy terms may sound trendy, but the technology to combat them often lags behind. While some larger companies do offer some customised solutions such as in-app notifications, most approaches are still reactive, such as updating email filters after an attack is detected or requesting takedowns of fake domains long after the damage is done. It's surprising that more proactive measures aren't in place, especially considering the serious consequences of these impersonation attacks. How B2V tackles this problem: - Mutual authentication: During critical communications, an organization can initiate an authentication session and share it with a user via a unique URL. When the user opens it, the organization provides a one-time password that the user can verify. These single-use ephemeral sessions also protect against man-in-the-middle attacks, ensuring that the person you're communicating with is truly who they claim to be. This could also be described as *conversational authentication*. - Digital signatures: Prove the authenticity and integrity of information linked to your organization with public-key cryptography. This is especially useful for verifying that text or links posted on platforms/media outside of your control — such as job boards, paper invoices, forums, or messages — truly come from a trusted entity. For example here's the signature of this post's URL: https://b2v.xyz/b2v_/XHEbx8NdqjTF50?s=https://news.ycombinator.com/item?id=40699265 - Verified online identities: Organizations can link their online identities, similarly to the way Keybase does it. For instance, here's the proof of ownership of this HN account: https://b2v.xyz/b2v_/NMiMMr9KWov6oE?s=hn:b2v - Privacy by design: this system respects your privacy by never tracking or storing plaintext identifying information, only digests and signatures. - For deeper integrations, an API is also available. Could this be useful for machine-to-human or machine-to-machine communications, such as chatbots or multi-agent LLMs? Any feedback would be greatly appreciated, especially about my assumptions! Feel free to check out the docs ( https://docs.b2v.xyz ) and ask me anything. Thanks! https://get.b2v.xyz/ June 17, 2024 at 12:33AM

Show HN: Alpha Demo of NotePad.ai (open source) https://ift.tt/p2dfL6h

Show HN: Alpha Demo of NotePad.ai (open source) Hi all, I threw together a small prototype I am calling “Notepad.ai”. A new take on UIs for interacting with LLMs. While I enjoy using LLM’s in the chat format I wanted to see what it would be like to do it in a more long form style. It let’s you write in a pretty free form, much like Window’s Notepad, but you can choose to hit ctrl+[ to analyze the text with a preset prompt of your choosing. It has a few other small features. It’s WIP and very experimental. I would appreciate any feedback or thoughts.

Show HN: I Made a Project Management Software for Freelancers After about 2 months of coding and many late nights I just finished building this simple project management tool that I designed to be specifically for freelancers. Tell me what you think, I am trying to get better at building with NextJS, thank you for any feedback. There is a 10 day free trial if you want to buy it outright. I made this as I didn't like the other tools out there and thought about how the tool could be specialised for freelancers. https://ift.tt/5J3oLyw June 16, 2024 at 12:05AM

Show HN: Summarize Trending GH Repos in Terminal or Browser https://ift.tt/CGL2iZB

Show HN: Summarize Trending GH Repos in Terminal or Browser Hey HN, I built a tool that fetches the daily trending GitHub repositories and uses GPT-4o to generate useful, detailed markdown-style summaries. The app then offers to render them in the terminal itself or as HTML, which is then opened your default web browser. I'm neither a trained programmer nor a computer science student, but I'm a geek nonetheless and had fun building this, so I wanted to share. Maybe it doesn't save anyone any time, but again, I had fun building it. Cheers! https://ift.tt/eBtQouW June 15, 2024 at 06:53AM

Show HN: 100% open-source voice assistant – as a HAL9000 https://ift.tt/0Cfcroj

Show HN: 100% open-source voice assistant – as a HAL9000 It started in 2018 with my first 3D printer and some openscad designs - just something that looks like a HAL9000 (and had a controlled red LED for the visuals) - it ended up being a full software-project...that hasn't ended yet. But: it is at a (quality-)point at which I am OK with putting it up on stage. My project goals: A digital voice-assistant that is... - actually usable (response times, error rates, ...) - performs everything on-device ("look ma, no cloud") - is entirely Free/Libre Open-Source-Software - is as-easy-as-possible to build I consider all four goals to be accomplished even at this ~90% stage of the project. If you just want to get some quick impressions, check out the "Demos" (video-)page in the github wiki (prominently linked in the README in the github repo). If you want to spend some more time on this, it's probably easiest to watch my presentation at Hackaday Europe from two months ago: https://www.youtube.com/watch?v=oqJCU8FRMQg&t=14761s https://ift.tt/YbTKxd7 June 15, 2024 at 05:57AM

Show HN: Epidemik a Python package for epidemic simulation https://ift.tt/vy9Y7S3

Show HN: Epidemik a Python package for epidemic simulation Hi everyone, I'm happy to share `epidemik`, a Python package for epidemic modeling. Epidemik, currently supports: - Homogeneously mixed Model: Easily define compartmental models by just specifying the transitions and rates - Age Structure: Convert any compartmental model to an age-structured model by simply adding an age contact matrix and a the population of each age group - Network Model: Easily define epidemic models running over an arbitrary network structure - Meta-Population Models: Define metapopulation model In a previous life (circa 2008-2012), I worked as the leading developer for a large-scale epidemic model so when CoVID hit I wrote a series of blog posts (see https://ift.tt/6WPcuD9 ) working through the mechanics of how this kind of model works. Epidemik is the result of all the code that got written during the lockdowns, and in the years since that, I finally cleaned up and decided to publish it in case others find it useful (perhaps as a teaching tool?) This is my first package, so feedback, comments and suggestions are definitely welcome. https://ift.tt/3bCspov June 12, 2024 at 12:41AM

Show HN: A keyboard-centric clipboard history app for macOS https://ift.tt/75BvuF6

Show HN: A keyboard-centric clipboard history app for macOS Hey HN, As a Software Engineer, I frequently copy and paste content. The fact that macOS clipboard buffer can keep only one item is very frustrating. It’s very annoying to copy → switch app → paste → switch app → copy → switch app → paste, and so on. Losing items I copied hours ago and having to find and copy them again is a waste of time. I tried many third-party clipboard managers like Alfred, Raycast, Paste, Maccy, etc. While great, they didn't fully meet my needs. As a developer, my requirements are: 1. Keyboard-centric operation to avoid using the mouse. I don’t want to waste my time moving my hands from the keyboard. 2. Display many clipboard history items at once. I don’t like the idea with big tiles, so I can see only 5-7 history items on my 32” monitor. 3. Full content preview for each clipboard item. 4. Quick search functionality. So, I created ClipBook for my own use. After months of development, daily use, and positive feedback from my colleagues, I decided to share it publicly. It’s free. All data is securely stored on your computer. I’m planning to make it open source as well. If you try it out, please let me know if you found it useful, if you have anything you’d like me to add, or if you have any other feedback. Happy to answer any questions. Much appreciated. https://clipbook.app/ June 11, 2024 at 10:10PM
