AONDevices is a provider of super low-power, high-performance on-device AI processors and full stack solutions that consists of machine learning chips, algorithms, a tool suite and training services. Running as a fabless semiconductor company specializing in application-specific edge AI processors with high accuracy at ultra-low power, the company launched its first AON1100 chip at CES 2023 in Las Vegas.
Traditionally, AI speech enhancement was performed using arrays of multiple microphones, beamforming and large Digital Signal Processing (DSP) algorithms. This method, currently implemented in today's smartphones and other devices such as smart speakers, requires huge amounts of memory and power. The problem is, today's consumers expect to have the same level of performance from miniaturized, battery-constrained devices such as true wireless stereo earbuds. Through its state-of-the-art, AI-based denoiser, AONDevices is addressing those requirements.
Known for its work in super low-power edge AI voice interfaces, AONDevices is expanding its signal processing focus to include innovations in communication and hearing enhancement. With just 50K parameters, the AONDenoise solution is one of the most compact denoising algorithms on the market. It is multiple orders of magnitude smaller than traditional DSP noise reduction methods and at least an order of magnitude smaller than current AI-based denoisers.
The AONDenoise solution addresses the need for customizable noise cancellation in ultra-low power, real-time processing devices, such as chips used for hearing aids. The algorithm can target a wide range of noises, such as chatter in a crowded restaurant, wind noise, dogs barking, babies crying, or keyboards clicking. And according to AONDevices, the solution has the potential to improve noise cancellation in different environments, including providing optimal audio quality in transparency mode, conversation mode, and voice calls.
Leveraging AI and deep learning neural networks, the AONDenoise solution can distinguish human speech from background noise. To maximize the efficiency of this neural network, AONDevices has developed a dedicated software tool suite. This allows both in-house and customer development to customize and train the system to handle specific noise environments or a broader range of noises.
"AONDenoise is a truly remarkable accomplishment in AI speech enhancement," says Dr. Youhong Lu, AONDevices' Technical Director. "A small yet incredibly effective algorithm that works with just a single microphone will positively impact many lives. I have been incredibly impressed by AONDevices’ achievements and am excited for the upcoming technology revolution in which AI delivers better user experiences."
Youhong Lu recently joined AONDevices after having previously served in high-level audio engineering roles for industry leaders including Conexant, Goodix, Plantronics, Verizon, and Microsoft. Mouna El Khatib, CEO of AONDevices is also the company's co-founder and chief technical officer, and previously held engineering leadership roles at Qualcomm as well as Conexant, a fore-runner of Irvine-based chipmaker Skyworks Solutions.
The AONDenoise solution is now available for integration into third-party processors. For developers seeking dedicated hardware solutions, AONDevices is preparing to launch the denoiser hardware IP and the associated next-generation chip – the AON2100.
