The research purpose of Artificial Intelligence (AI) is to expand human intelligence by exploring the essence of intelligence-to make intelligent agents listen (speech recognition, machine translation, etc.), see (image recognition, character recognition, etc.), speak (speech synthesis, man-machine dialogue, etc.), think (man-machine game, expert system, etc.) and learn (knowledge representation, machine learning, etc. A classic definition of AI is: "Intelligent agents can understand data and learn from it, and use knowledge to achieve specific goals and tasks. (A system’s ability to correctly interpret external data, to learn from such data, and to use those learnings to achieve specific goals and tasks through flexible adaptation)”

The whole house is clean, and Si Bichi calls AI to sweep the floor ＂monk＂
With the growth of household disposable income, post-80s and post-90s gradually become the main force of household consumption. Smarter and healthier sweeping robots, glass cleaning robots, smart toilets, dishwashers and other emerging household appliances are popular. According to relevant survey data, 62.8% of the respondents indicated that they needed a sweeping robot, and thought that this product greatly saved their time and energy.
Aiming at the high noise characteristics of cleaning robots such as sweeping/dragging, Spirits has launched an intelligent sweeper solution. Equipped with Spitz ring 4 microphone array, built-in AI voice dedicated chip TH1520, combined with traditional signal processing+deep neural network noise reduction algorithm, it can effectively eliminate the self-noise and environmental noise of the sweeper, and with the full-link voice language interaction technology, the whole house is clean and barrier-free, and naturally calls the "monk" to sweep the floor.
Far-field interaction, omnidirectional pickup
With the help of big data, edge computing, artificial intelligence and sensors, the sweeping robot industry has developed at a high speed, and its functions have been continuously optimized, achieving better cleaning effect and user experience. As one of the most intelligent cleaning products, sweeping robot has won the unanimous favor of consumers. Relevant data show that by the end of November 2022, the offline retail sales of sweeping robots increased by 21.8% year-on-year.
In the home scene, far-field voice interaction has the characteristics of low signal-to-noise ratio, low signal-to-interference ratio, low signal-to-return ratio and serious multipath interference. Aiming at the problem of far-field interaction, Spitz intelligent sweeper solution is equipped with Spitz ring 4 microphone array, which can realize far-field interaction of 5 meters or more in home environment and 360 wide range pickup; The sound source location technology based on multi-dimensional strategy has a sound source location error of 5; The wake-up rate of equipment is over 95%, and the recognition rate is over 92%.
In addition, the scheme also optimizes the models of different timbres, so that the elderly and children at home can easily give instructions. No matter where the user is in the living room, bedroom or kitchen, he can interact with the sweeping robot in the far field, "start cleaning the living room", "go to the kitchen to clean" and "turn to the silent mode", so that the whole house can be cleaned easily without hands.
AI chip, faster interaction
In order to make the machine understand human speech and realize better voice control. Spitz intelligent sweeper solution has built-in AI voice chip TH1520, which supports 100+ offline instructions and makes interaction faster and more convenient. Users can start the whole house cleaning action by issuing voice commands without using mobile phones or remote controls.
TH1520, the AI voice chip, adopts the method of soft and hard integration, which makes the chip have the ability to quickly give voice interaction to various devices, and has the characteristics of strong performance, low power consumption, off-line/on-line, flexible and rapid deployment, which greatly improves the user experience and product flexibility.
The chip integrates Spitz full link intelligent dialogue technology and is modularized and packaged. In the far field and complex sound field environment, it can realize efficient identification and rapid response; The power consumption is as low as milliwatts, the power consumption of typical working scenes only needs tens of milliwatts, and the peak power consumption of extreme scenes does not exceed 100 milliwatts; With ultra-high customization ability, you can customize wake-up words and synthesized sounds, select broadcast timbre, and support voiceprint recognition and dialect recognition; Off/on-line dual-mode hybrid interaction, full-duplex interaction, nearby wake-up, multi-module collaboration, call noise reduction and other high-level natural interaction capabilities.
Intelligent noise reduction, summoning "monks" to sweep the floor
Keeping the family clean is actually a big project, especially for families with pets or babies, which is time-consuming and labor-intensive. With the development of artificial intelligence, Internet of Things and other technologies, the sweeping robot with the functions of voice control, automatic dust collection, intelligent obstacle avoidance, whole house planning and deep cleaning has become a good helper for family cleaning.
The voice interaction in the home space needs to overcome the interference of all kinds of noise. Spitz intelligent sweeper scheme, built-in Spitz customized far-field call noise reduction algorithm, makes the sweeper act as a mobile monitoring device, picks up clear voices, and can monitor abnormal sounds. Customized active noise reduction+deep learning noise reduction algorithm for high noise scenes can effectively reduce machine noise by 20db；; Customized adaptive wake-up algorithm, the false wake-up rate is less than 1 time /48 hours, and the wake-up rate is effectively doubled.
At present, Spitzer’s intelligent sweeper scheme has landed in pursuit of exclusive edition of luxury cleaning flagship X10, series of fully automatic sweeping and towing integrated robot S10 Plus, and new 10th generation sweeping and towing flagship W10s Pro. Thanks to the support of Spitz’s intelligent sweeper solution, Chasing products can effectively eliminate the self-noise and environmental noise of the sweeper, support full-scene voice commands, and realize natural human-computer interaction.
Adhering to the mission of "communicating everything and taking care of everything", Spirits relies on AI technology to empower many industry scenarios and constantly explore and optimize smart life segmentation scenarios. In the future, Spirits will continue to provide more artificial intelligence technologies and products and services combining software and hardware for the home field, create a futuristic living space and realize universal intelligent human-computer information interaction.
