Voice recognition service demand is rising. With Amazon's Alexa and Google's application services such as Ok Google becoming more mature, users' requirements for voice recognition will be more stringent. The AcuEdge Development Kit for Amazon AVS is a complete development kit with a development board directly connected to the Raspberry Pi processing unit and plastic frame to support placement of microphones and speakers in targeted applications. To further enhance the audio processing capabilities to enable emerging human-machine interconnect (H2M) applications to improve speech recognition rates in harsh audio environments in the IoT, Industrial IoT, and Automated Assist markets, Microsemi ( Microsemi has launched the AcuEdge Development Kit development kit; it is understood that this development kit is currently available in the Alexa Voice Service (AVS). Shakin Sadeghi, marketing director of Microsemi, said that many smart home appliances similar to Alexa can be found in the market recently; the company's suite supports third-party developers and original equipment manufacturers to evaluate their H2M using the AcuEdge Development Kit. Applications, as well as the introduction of voice recognition, allow customers to quickly develop product development schedules. In addition, the AcuEdge Development Kit also provides an interface to the company's TImberwolf ZL38063 multi-microphone audio processor; it is understood that the company's TImberwolf series is a field-programmable, field-upgradeable digital signal processor that is operational A special hardware accelerator for three sets of Synchronous Acoustic Echo Canceller (AEC). Sadeghi further stated that the AcuEdge Development Kit for Amazon AVS is a complete development kit with a development board directly connected to the Raspberry Pi processing unit and plastic frame to support placement of the microphone and target in the target application. speaker. It is understood that TImberwolf is equipped with a compressor / limiter / expander (CLE) microphone pickup algorithm, beamforming, and fixed and non-stationary noise suppression technology, which can improve the effective distance of voice control and voice recognition. Sadeghi stated that even if it is four to five meters away from the device, it can be clearly heard, and it can be used in places with unfavorable noise and audio sound. This kit comes with a TImberwolf evaluation board and a Raspberry Pi connector for fast and easy setup. In addition, the kit comes with a board and speaker stand that allows users to quickly evaluate the performance of the solution. While the Raspberry Pi runs the Amazon AVS client and Alexa wake-up words, the Timberwolf solution also runs a variety of audio processing functions to dramatically improve speech recognition accuracy. Silicon Transistor are solid-state semiconductor devices with functions such as detection, rectification, amplification, switching, voltage regulation, and signal modulation. The transistor acts as a variable current switch and can control the output current based on the input voltage. Unlike ordinary mechanical switches (such as Relay and switch), transistors use electrical signals to control their opening and closing, and the switching speed can be very fast. The switching speed in the lab can reach more than 100GHz.
