Standard Intelligence Inc. has recently unveiled a groundbreaking open-source audio model, Hertz-dev, poised to revolutionize real-time conversational interaction for organizations across industries. From possibilities such as customer support agents to interactive voice-driven analytics, Hertz-dev is the first of its kind. With unprecedented low latency averaging just 120ms in real-world conditions with consumer-grade equipment, this new model empowers developers to design and deploy applications which can respond with human-like immediacy in conversation. Importantly, it is licensed with the popular Apache-2.0 open-source license, allowing the model to be used in commercial enterprises and organizations. With further development organizations can expect a vast swath of options for conversational AI programs that sound natural and engaging.

The Breakthrough Behind Hertz-dev: An Open-Source Audio Model
Hertz-dev stands out as the world’s first open-source audio base model designed specifically for conversational audio generation. Comprising a relatively small model at 8.5 billion parameters, it combines several critical innovations, including a full-duplex transformer, enabling seamless back-and-forth interaction with the voice model. By releasing this model into the open-source community, Standard Intelligence empowers AI developers, researchers, and enterprises to experiment and build on this powerful foundation, advancing their own voice-enabled technologies.
Redefining Efficiency with Hertz-codec
A core component of Hertz-dev, Hertz-codec, is a convolutional audio autoencoder tailored to efficiently process audio data. It takes mono, 16kHz speech and compresses it into an 8Hz latent representation, with a remarkably low bitrate of about 1kbps. This codec is not only more efficient than other leading solutions—outperforming Soundstream and Encodec at higher bitrates—but also produces highly compressed, quality audio with minimal latency. The result is faster, smoother language modeling, ideal for real-time applications and interaction where responsiveness is key.
Enhanced Audio Generation with Hertz-vae
Hertz-dev incorporates a 1.8-billion parameter transformer known as Hertz-vae. This audio Variational Autoencoder (VAE) uses a predictive framework to steer audio generation, creating coherent, continuous speech. With the ability to handle 17 minutes of input in its context-based memory, Hertz-vae allows the model to maintain coherence over extended interactions, making it perfect for applications requiring prolonged conversational engagement. It’s these features that set Hertz-dev apart, enabling real-time interactions that feel natural rather than mechanical.
Low-Latency Processing with Hertz-dev’s Transformer Stack
At the heart of Hertz-dev is its transformer stack, a 6.6-billion parameter model designed to maximize conversational flow. Partially initialized from pre-trained language model weights and trained on an impressive 500 billion tokens. With real-world latency averaging around 120ms this is significantly faster than any other publicly available open-source model, making it ideal for AI solutions requiring near-instantaneous response times, such as virtual assistants, customer-support, NPCs in game development, or interactive learning platforms.
A Glimpse into the Future of Voice Interaction
Hertz-dev provides a foundation for researchers and developers eager to explore and innovate within real-time audio modeling. Its focus on usable latency and open-source accessibility invites a wide array of fine-tuning opportunities, supporting use cases that range from telecommunication to virtual reality. The scalable nature of Hertz-dev also hints at what lies ahead: even more advanced conversational models with greater coherence and expressive capabilities, thanks to ongoing development and reinforcement learning and fine-tuning.
