STMicroelectronics, DSP Group and Sensory jointly develop voice control equipment keyword smart microphone

     STMicroelectronics, the world's leading semiconductor supplier and the world's top MEMS supplier across multiple electronic applications, and DSP Group, the world's leading provider of converged communication wireless chipset solutions, and the world's largest developer of voice interfaces and keyword detection algorithms Sensory Co., LTD., jointly announced the technical details of the high efficiency speech detection processing microphone. The microphone is compact and has keyword recognition.

    The device integrates ST's low-power MEMS microphone, DSP Group's ultra-low-power voice processing chip and Sensory's voice recognition firmware in a micro-system package (SiP), leveraging ST's advanced packaging technology to achieve a very lightweight package, extremely long battery life and advanced features.

     Typical Sound Wake up microphones can wake up the device and exit sleep mode without the user touching it. However, due to limited processing performance, the main system processor needs to be woken up to recognize the received instructions. With the powerful computing power of the DSP Group voice processor, ST microphones can detect and recognize commands without waking up the main system, achieving efficient and intuitive seamless human-computer interaction, which is suitable for scenarios where users issue voice commands to voice-activated appliances such as smart speakers, TV remote controls, and smart home systems.

     Using DSP Group's HDClear ultra-low power audio processing chip, the new microphone solution extends the life of battery-powered devices for many years without needing to recharge or replace the battery. The system executes commands immediately without the need to identify commands in advance, so voice commands respond faster.

     Andrea Onetti, General Manager of MEMS Devices and Sensors Products at STMicroelectronics, said: "Unlike existing solutions, the new microphone not only listens to sound, but also understands voice commands immediately, eliminating the need for main processor resources and computing resources. "Iot hardware and applications, including Industry 4.0. devices, are adding voice interfaces, and this intelligent integration technology is an important part of making it possible."

     Ofer Elyakim, CEO of DSP Group, said: "As voice control becomes the default user interface, more and more innovative products are introducing intelligent voice processing technology. Our solutions combine small packages, high integration and low power consumption to enable a seamless, energy-efficient voice user interface within battery-powered devices. By partnering with industry leaders ST and Sensory in the smart microphone market, we are bringing to market a best-in-class, energy-efficient solution for smart systems that require integrated quality voice capabilities."

     Todd Mozer, CEO of Sensory, added, "Voice control has the potential to revolutionize the way people interact with a variety of appliances, mobile devices or office devices. St's new high level of integration solution integrates our latest firmware to enable Oems to provide end-users with a natural and easy human-machine interaction experience."
