Realtek’s Multi-Mic Far-Field Speech Recognition Enhanced Single Chip Solution (ALC5520) Wins Innovative Product Award 2018


HSINCHU, Taiwan – December 12, 2018 – Realtek Semiconductor Corp. (Taiwan Stock Exchange: 2379.TW), one of the world’s leading IC providers, today announced that its Multi-Mic Far-Field Speech Recognition Enhanced Single Chip Solution (ALC5520) has received an Innovative Product Award 2018 from the Hsinchu Science Park Administration in Taiwan.

Realtek’s ALC5520 Audio/Voice DSP is a total solution for Far-Field Voice applications. The integration of embedded 103dB SNR Hi-Fi, low power ADC, multi-core 32-bit DSP with vFPU, and Realtek proprietary voice processing technology greatly enhances the Speech Recognition performance of the ALC5520, even in very noisy and far-field (over 10 meter) environments.

Realtek’s ALC5520 provides ultra-low power consumption and a highly integrated total solution in a competitive package size (QFN 8x8mm), and offers the following technical and market advantages:

● Total solution for Far-Field Voice applications
● 103dB SNR HiFi low power ADC
●High performance multi-core 32b DSP with vFPU
● Ultra-low power consumption design
● Excellent Speech Recognition enhancement in very noisy and far-field environments
● Compact rBOM and PCB size for end-product
● Easy addition of voice capability to any type of application/product

“The high performance and ultra-low power design enables the ALC5520 to be widely adopted in products requiring voice input and recognition functions, such as smart speaker, smart TV, mobile device, white goods, and automotive electronics”, said Realtek’s Vice President and Spokesman, Yee-Wei Huang. “Realtek's ALC5520 not only establishes a higher entry barrier for speech recognition enhancement, but also speeds voice technology acceptance in various industrial products”.
