has become nvidia One of the world’s most valuable companies Thanks to the stock market in recent years, seeing how much demand is for graphics processing units (GPUs), which creates powerful chips NVIDIAs that are used to present graphics in video games, but fast, AI trains large language and dispersion models.
But NVIDIA only works more than making hardware, and making software to run it. Since the Generative AI ERA, the Santa Clara-based company has been releasing more and more AI models-most of the open-source and the latest for researchers and researchers and developers are free to modify and use them. Parakat-TDT -0.6 B-V 2Identity of an automatic speech (ASR) who, can I be Facial Waboo “VB” Srivasto words to embrace, “Copy of 60 minutes of audio in 1 second (blowing emoji).”
This Parakate Model is a new generation of Nvidia is the first time in January 2024 and it has been updated again April of this yearBut this version is two so powerful, at the moment it is at the top Hugs face open ASR Leader Board With average “literal error rate” (times the model incorrectly imitate a word) only 6.05 % (100 out of 100).
In this context, it is near the IT, it is close to the proprietary transcript model such as Openi’s GPT -4OO Transkib (with a WER of 2.46 % in English) and eleven labs (3.3 %).
And it is all presenting it while commercially permitted under permission Creative Affairs CC-BY-4.0 LicenseIt makes an attractive proposal for commercial businesses and Indi developers who seek to prepare speech recognition and duplication services in their payment requests.
Performance and benchmark standing
The model contains 600 million parameters and takes advantage of the combination of festicular manufacturer encoder and TDT decoder architecture.
It is only capable of copying audio one hour in one second, provided it is running on a sharp hardware from NVIDIA’s GPU.
The performance benchmark is measured on 3386.02 RTFX (real -time factor), with the size of 128, and hugging it in the upper part of the existing ASR benchmark.
Use matters and availability
Released globally on May 1, 2025, the purpose of the Parakat-TDT-0.6 BV2 is to make applications such as developers, researchers, and industry teams such as transcript services, voice assistants, subtitles generators, and exchanged AI platforms.
The model supports the time stamping of the surface, capital and detailed words, which offers a full transcript package for a wide range of text needs from speech.
Access and deployment
Developers can deploy the model using NVIDIA growth toolkit. The setup process is compatible with pitcher and piturich, and the model can be used directly or fine tones for domain -related tasks.
Open source license (CC by 4.0) also allows commercial use, which appeals to startups and enterprises equally.
The development of the training data and model
The Parakat-TDT-0.6 B-V2 was trained on a diverse and widely trained carpus, called Greenry Dataste. It contains about 120 120,000 hours of English audio, which contains 10,000 hours of high quality human transfer data and 110,000 hours of stirring speech.
Sources are from leading datases, such as Labor Ipt and Mozilla Common Voice to YouTube Commons and Libless.
NVIDIA plans to make the granular dataset publicly available after its offer in Interpack 2025.
Diagnosis and tightly
This model was diagnosed in a multiple English -language ASR benchmark, which includes AMI, income 22, gigaspich, and spacespikes, and was generally performed in general. It is strong in various noise situations and performs well with telephone -style audio formats, which only has a slight decline in the proportion of low signal -to -noise.
The compatibility and performance of hardware
Parakat-TDT-0.6 B-V2 Nvidia has been improved for the GPU environment, which supports hardware such as A100, H100, T4, and V100 boards.
Although high -end GPUs perform more and more, this model can still be filled on a minimum 2GB of RAM system, which allows wider deployment scenario.
Ethical reservations and responsible use
Nvidia notes that the model was developed without the use of personal data and is responsible for the AI ​​framework.
Although no specific steps were taken to reduce the settlement bias, the model approved the internal standard standards and included detailed documents on its training process, datastate provision, and privacy compliance.
The release attracted attention to machine learning and open source communities, especially after public lighting on social media. Observers noted the ability to improve trade ASR alternatives while fully open source and commercially usable.
Developers interested in trying the model can access through this The hugs face Or through the NVIDIA growth tool cut. Installation instructions, demo scripts, and integration are readily available to facilitate experience and deployment.
