VocalZoom and iFLYTEK Partner to Give China’s Most Popular Speech Recognition Platform Breakthrough Performance in Noisy Environments

By Business Wire News   


VocalZoom, a leading supplier of Human-to-Machine Communication (HMC) optical sensors that enable a more natural, personalized and secure voice-control experience, today announced it has signed an agreement with iFLYTEK to combine and test the performance of VocalZoom’s optical HMC sensor with iFLYTEK’s Voice Cloud intelligent speech technology platform, China’s most widely deployed solution with hundreds of millions of users. Initial results show that the ASR performance of iFLYTEK’s platform can be improved an average of 50 percent, and even more in noisy environments, by adding VocalZoom sensors to user headsets and automotive infotainment solutions.

“iFLYTEK is already the best-performing voice-control solution by a number of global standards across all popular benchmark test domains, but the biggest challenge is noisy environments and we believe that VocalZoom technology gives us the foundation for breakthrough improvements,” said Haikun Wang, senior researcher at iFLYTEK. “We have tested the VocalZoom sensor in scenarios including the inside of a moving automobile with the windows rolled down and high wind noise, and the improvement is quite substantial.”

The key for human-to-machine interactions using virtual assistants and automotive voice control is whether the machine did what it was told, quickly and accurately enough to satisfy the user. Even with the latest noise reduction algorithms, today’s acoustic microphones can’t achieve adequate voice isolation for this level of control, especially in noisy environments. The VocalZoom multifunction HMC sensor overcomes this problem by gathering additional data generated during speech as facial skin vibrates around the mouth, lips, cheeks and throat. By integrating the VocalZoom optical HMC sensor into a voice-control solution and focusing it on these areas, facial vibrations can be acquired, measured and converted to an isolated, near-perfect reference signal with which the system can operate – regardless of noise levels.

“We are excited to be working with iFLYTEK to significantly improve the performance of one of the most widely deployed ASR platforms,” said Rammy Bahalul, vice president of sales and business development for VocalZoom. “VocalZoom and iFLYTEK intend to complete our joint testing this month as we explore opportunities to combine our two technologies into a revolutionary new solution for voice control and authentication. We share the vision of a significantly better voice-control experience using smaller, sleeker headsets and other solutions across a wide variety of applications.”

VocalZoom and iFLYTEK have tested the performance of a solution combining both companies’ technologies inside a moving automobile across a number of scenarios with varying levels and combinations of music, car noise and other interference. ASR performance is improved to an almost perfect score in environments where high noise previously made adequate voice-control performance impossible.
