Language is an important way for people to transmit and obtain information. With the development of speech recognition technology, this interaction mode has also been applied to people and machines. It can be said that speech recognition technology is one of the key breakthroughs to achieve artificial intelligence. In the post epidemic era, non-contact equipment against the spread of the epidemic has been widely developed, and voice recognition technology, as a precise and non-contact technology, has also attracted much attention. In this context, Dalianda Pinka launched the Amazon intelligent Internet of Things speech recognition scheme based on MediaTek Filogic 130A (MT7933), which combines advanced Wi Fi and Bluetooth functions with the latest voice processing and power management technologies to provide high-quality choices for smart homes and home entertainment systems.
