Syntiant: Optimizing Silicon and Deep Learning Models to Customize Voice Experiences at Edge


Syntiant is enabling customized voice experiences at the edge, across multiple products and use cases including wake word, command control, and event detection, free from cloud connectivity, ensuring privacy and security.

Headquartered in Irvine, California, Syntiant Corp. is moving artificial intelligence (AI) from the cloud to edge devices. The company’s advanced chip solutions merge deep learning with semiconductor design to produce ultra-low-power, high performance, deep neural network processors for always-on applications in battery-powered devices, such as hearing aids, earbuds, smart speakers, mobile phones and laptops.

Backed by some of the world’s strongest strategic investors, including Intel Capital, Microsoft M12, Bosch Ventures, and the Amazon Alexa Fund, Syntiant’s deep learning “intelligent voice” solution opens new markets and business opportunities for customers as demand for speech grows globally.

The company’s highly accurate, ready-to-use, always-on voice solution adds wake word and speech control (in multiple languages) to any smart device, with ultra-low-power and greater efficiency. Other applications include sensors, event detection, and speaker recognition.

Custom built to run AI workloads, the Syntiant® NDP100™ and Syntiant® NDP101™ microwatt-power Neural Decision Processors™ (NDPs) improve efficiency by 100x and throughput by 10x vs. traditional microcontroller units (MCUs).

The company also protects user privacy and security by deploying deep learning at the edge, while lowering costs due to die size, as well as enabling implementation into the smallest devices. Syntiant also collects and trains its own data. Technical specs  on the company’s NDPs can be found by clicking on the following links: and


A Mission to Succeed in Disruptive Market

Founded in late 2017, Syntiant is driven by a global mission of bringing AI voice solutions to edge devices, free from touch and cloud connectivity, and that are more useful, more efficient, and more safe and secure.

The company’s deep learning voice technology is leading the way toward universal hands-free functionality, changing the way people interact with their devices.

Syntiant has moved very fast, from closing its Series A round in October 2017, to sampling its first products in June 2018, to closing its Series B round in October 2018. In September 2019, the company started shipping its Syntiant Neural Decision Processors (NDPs) to customers across the globe.

Designed into a wide range of battery-powered devices, Syntiant expects the first of these NDP-embedded consumer products to be available this year.


A Leadership with Futuristic Vision

Tech veteran and CEO of Syntiant, Kurt Busch is quickly building Orange County’s next great chip company. He along with Jeremy Holleman, Ph.D., Chief Scientist; Pieter Vorenkamp, COO; and Stephen Bailey, Ph.D., CTO, and Chief Architect; founded Syntiant using a clean-sheet design for AI processors to make voice the new user interface of the future.

Kurt has extensive experience in product development, having driven the successful launch of new products, ranging from SAS and semiconductors for telecom and broadcast video to consumer electronics and data center systems. Prior to Syntiant, he was President, CEO, and a member of the Board of Directors at Lantronix (NASDAQ: LTRX), a global provider of secure data access and management solutions for the Internet of Things (IoT) and information technology (IT).

Kurt has also served as a Senior Vice President and General Manager of a high-performance analog business unit at Mindspeed Technologies, acquired by MACOM. He served at the University of California at Irvine’s (UCI) alumni board for six years, dedicating his time to help graduates find success after college. Kurt is a member of the UCI CEO Roundtable and an inductee of the UCI School of Engineering Hall of Fame. He recently was recognized by UCI’s School of Engineering with the school’s Lauds & Laurels Distinguished Alumni Award.

Also, a member of the Global Semiconductor Alliance, Kurt earned Bachelor of Science degrees in electrical engineering and biological science at UCI and holds a Master of Business Administration from Santa Clara University.


Extending Quintessential Innovations for Industry-Demands 

Using a co-design methodology that optimizes silicon and deep learning models together, Syntiant’s architecture achieves breakthrough performance by slashing power consumption while increasing throughput. The result is an inference solution capable of intelligent processing with months of always-on life from a coin-cell battery, providing consumers a smart device experience in battery-powered edge devices.

With over 500k parameters, far more than available on typical microcontroller-based neural solutions, Syntiant’s NDP100 and NDP101 microwatt-power processors provide the neural capability for accurate inference on challenging tasks, supporting up to 64 different events that could include words, audio events such as breaking glass or gunshots, or other sensor inputs such as gas or vibration.

Syntiant’s NDPs also can serve as an always-on gate-keeper, providing a significant classification of events, allowing larger systems to remain dormant until absolutely needed. With support for multiple programmable words, Syntiant’s technology expands the voice interface from simple wake words to a command language model, enabling a local speech control interface that does not require a cloud connection, increasing security and ensuring privacy.

Syntiant’s NDPs are now available for use with the Amazon Alexa Voice Service (AVS). As a low-power processor for close-talk voice-enabled devices, the company’s neural network technology allows customers to offer a built-in Alexa experience to even the most power-sensitive battery-powered devices.


Moving Towards an AI-Driven Reality

Kurt believes that “As our world becomes increasingly interconnected through data and technology, we are inching closer to a reality that’s driven by artificial intelligence, the merging of our physical and digital lives.”

According to him, Edge AI is at the heart of this paradigm shift. More importantly, Syntiant’s technology is enabling customers to bring deep learning to battery-powered devices at the edge with significantly less power consumption than current MCUs and without cloud connectivity.

In remote parts of the world, for example, Syntiant’s NDPs easily can enable the lowest-cost feature phone to listen to the human voice, enable a voice assistant and use the Internet just like a very high-end smartphone.

Similarly, high-performance neural networks at the edge are essential for demanding public safety environments and industry operations. According to Scott Mottonen, Corporate Vice President, devices at Motorola Solutions, “Syntiant’s deep learning neural decision processors can provide users working remotely in the field with enhanced safety and efficiency by powering a new breed of applications at the edge.”

The company’s NDPs incorporates an optimized neural network architecture supporting more than 500,000 weights to bring significant neural processing power to a very small energy footprint. This level of neural processing enables voice interfaces in even the harshest environments.

At the nexus of technology and social reform, lies the concern over security and privacy. By running inference on the local device, the company’s neural technology avoids the privacy risk incurred by transmitting personal data to potentially insecure servers.

From enhanced functionality and better productivity to improving safety and privacy, Syntiant’s technology is impacting innovation, making AI at the edge a reality.


Advancing with New-Age Technologies and Significant Partnerships

Deep learning has provided a toolset that yields vastly superior decisions to traditional methods based on human intuition, essentially making devices smarter through the use of AI voice solutions.

However, deep learning methods are computationally intensive. Traditional semiconductor solutions for advanced deep learning at the edge are severely limited by excessive power dissipation.

With a power consumption of less than 140µW and package sizes down to 1.4mm X 1.8mm, the company’s neural decision processors provide battery-powered consumer products typically 100x more efficiency and 10x the throughput of the typical low-power MCU solution.
