The speech recognition market is tamping. According to research by Strategy AnalyTIcs, a market research agency, by 2022, it is estimated that there will be more than 62 million devices in the global consumer market with personal voice assistants. In order to intervene in this market, the semiconductor industry has launched a new generation of solutions. For example, Infineon combines radar, MEMS microphones and audio processors to further improve the voice recognition performance of MESM microphones; ST is working with the developer of voice interfaces and keyword detection algorithms-Sensory and communications DSP Group, a supplier of wireless chipset solutions, has jointly developed microphone technology for efficient voice detection and processing. According to Lu Peiru, an analyst at the IEK Electronics and Systems Research Group at the Industrial Research Institute, although voice assistant services are still in their infancy, with the rapid growth of market demand, smart home appliances, in-vehicle systems, and even more IoT devices will penetrate in the future Application. At present, semiconductor manufacturers, telecommunications companies and other companies who want to enter the voice recognition market, in addition to actively developing related applications, how to improve voice recognition performance is also a key development direction in the future. To this end, the semiconductor industry accelerates its layout. Infineon combines radar, silicon microphone sensor, and XMOS audio processor to provide far-field voice capture function through audio beamforming and radar target presence detection technology to ensure that a wide range of voice control devices can perform Ideal voice recognition to perform digital voice assistance functions, thereby improving the dilemma of the MESM microphone cannot accurately identify the location of the voice source and cannot separate from the murmurs emitted by objects when talking with multiple people. It is reported that Infineon's 60GHz 2Tx / 4Rx radar IC with the included antenna and 70dB SNR microphone will help overcome these obstacles. This microphone uses the company's dual backplane MEMS technology and is suitable for far-field voice acquisition and beamforming. In addition, the improved SNR of the microphone will also further enhance the performance; and the XMOS audio processor will analyze the signal data from the company's digital microphone array, and adjust the angle and distance data provided by each microphone, in the angle of radar data identification Beam forming. Through the combination of radar and XMOS beamformer, even if the object is moving and there is blurry noise, the microphone can accurately target the specific object. On the other hand, the law of law is to join hands with the DSP Group and Sensory to announce the technology of efficient voice detection and processing microphones. This component integrates ST's low-power MEMS microphone, DSP Group's ultra-low-power voice processing chip, and Sensory's speech recognition firmware in a miniature system-in-package (SiP) to achieve light weight through the company's advanced packaging technology Quantitative packaging, long battery life and advanced functions. At the same time, the new microphone uses the DSP Group's HDClear low-power audio processing chip, which can greatly reduce energy consumption and extend the battery life of battery-powered equipment for many years without the need to recharge or replace the battery; and the system immediately executes the command without pre-recognizing the command. Voice command response speed will be more rapid. 10 KV Oil Immersed Transformer 10 Kv Oil Immersed Transformer,10Kv Oil Immersed Transformer,500Kva/630Kva 10Kv Oil Immersed Transformer,Efficient 10 Kv Oil Immersed Transformer Tianhong Electric Power Technology Co., Ltd , https://www.tianhongtransformer.com
