24 alternatives to KVoiceWalk – Voice cloning for Kokoro TTS using random walk algorithms
I was blown away by Kokoro and what it managed to do with such little space. I became curious if it would be possible to create new voices by direct manipulation of the style tensors. After many failed attempts I finally landed on a method that properly scores the similarity of two audio segments that works well enough to random walk similar voices for Kokoro. I plan on using this scoring as part of a genetic algorithm, but wanted to baseline test it with this code. The scoring mechanism using Resemblyzer to calculate similarity to target audio and similarity to another segment of audio it…
KVoiceWalk is a tool for creating new voices with Kokoro TTS by manipulating style tensors using random walk algorithms. It works by scoring audio similarity using Resemblyzer to measure how closely generated audio… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Prices are shown for the 1 we have checked on their own sites, 1 of them free or with a free tier.

Hey there, I’m Brian. I've been shipping conversational models over here at Tavus for the past two years. I want to tell you about our new audio-understanding model: Sparrow-2! It’s a new category of model and a unique new approach to conversational audio. Earlier this year we launched Sparrow-1, (at the time) our SoTA turn taking model. Since our Sparrow-1 launch, I’ve spent a lot of time listening to humans talking and trying to really understand how people know when to talk, when to listen, and when to wait. I’ve also been hunting down failure modes of the current SoTA models. And while…

I built KokoClone, a small project that adds zero-shot voice cloning on top of Kokoro TTS. The idea was to keep Kokoro’s speed and real-time compatibility while allowing speech to be generated in the timbre of a reference voice. You can type text, upload a ~3–10 second voice sample, and generate speech in that voice. Supports several languages including English, Hindi, French, Japanese, Chinese, Spanish, Portuguese, and Italian. Runs on CPU and can use GPU if available. Live demo: https://huggingface.co/spaces/PatnaikAshish/kokoclone Would appreciate feedback.

Vaani▲308We kept seeing the same problem: creators make great content but the moment they dub it into another language, everything falls apart. Robotic voice. Music gone. Meaning lost. Lips not matching. So we built Vaani. Whatever language you create in, wherever you are in the world, your content can reach a global audience. We clone your voice, match your gestures, preserve your music, and optionally sync your lips to the new language. 10+ Indian languages, 20+ global languages, all in minutes. We built it for 2 reasons: So creators never have to sound like a robot in another language again So the…

In 2020, Magenta released DDSP [1], a machine learning algorithm / python library which made it possible to generate good sounding instrument synthesizers from about 6-10 minutes of data. While working with DDSP for a project, we realised how it was actually quite hard to find 6-10 minute of clean recordings of monophonic instruments. In this project, we have combined the DDSP architecture with a domain adaptation technique from speech synthesis [2]. This domain adaptation technique works by pre-training our model on many different recordings from the Solos dataset [3] first and then…

Inworld TTSfree tier, from $25/mo▲318Hey HN, this is Igor, one of the engineers behind Inworld Runtime, which we're releasing today in public preview. We built it to solve the common problem we and our customers had: engineers spend more time on AI ops and plumbing than on actual feature development. This was often due to the challenge of using Python for I/O-bound, high-concurrency workloads and complexity maintaining pipelines with streams that use always-changing ML models. Our solution is a high-performance runtime written in C++ with the core idea of defining AI logic as graphs. For instance, a basic voice-to-voice…

I built k-synth as an experiment to see if a minimalist, K-inspired array language could make sketching waveforms faster and more intuitive than traditional code. I’ve put together a web-based toolkit so you can try the syntax directly in the browser without having to touch a compiler: Live Toolkit: https://octetta.github.io/k-synth/ If you visit the page, here is a quick path to an audio payoff: - Click "patches" and choose dm-bell.ks. - Click "run"—the notebook area will update. Click the waveform to hear the result. - Click the "->0" button below the waveform to copy…

This is part of my journey on pybind11. I wrote a tiny FM Synthesis library in C++ and a Python wrapper for that using pybind11. There is a command-line piano app in the examples directory if you want to play with it. Here is the link: https://github.com/charstorm/koelsynth/tree/main/examples/si... My next target is to attach this to some kind of physics simulation - like a bunch of balls moving around in a box with some internal walls. When the ball hits certain trigger points, it produces the sound.

Our goal with this project is to build a completely open source, state of the art turn detection model that can be used in any voice AI application. I've been experimenting with LLM voice conversations since GPT-4 was first released. (There's a previous front page Show HN about Pipecat, the open source voice AI orchestration framework I work on. [1]) It's been almost two years, and for most of that time, I've been expecting that someone would "solve" turn detection. We all built initial, pretty good 80/20 versions of turn detection on top of VAD (voice activity detection) models. And…

TLDR: We created a personalised Andrej Karpathy tutor that can response to questions about his Youtube videos in sub 1 second responses (voice-to-voice). We do this using a voice enabled RAG agent. See later in the post for demo link, Github Repo and blog write up. A few weeks ago we released the worlds fastest voice bot, achieving 500ms voice-to-voice response times, including a 200ms delay waiting for a user to stop speaking. After reaching the front page of HN, we thought about how we could take this a step further based on feedback we were getting from the community. Many companies were…
