This document is in accordance with the provisions of GB/T 1:1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents" Drafting: Please note that some of the contents of this document may involve patents: The issuing organization of this document does not assume the responsibility for identifying patents: This document was proposed by the China Electrical Equipment Industry Association: This document is under the jurisdiction of the National Technical Committee for Standardization of Household Automatic Controllers (SAC/TC212): This document was drafted by: Guangdong Midea Refrigeration Equipment Co:, Ltd:, China Electric Power Research Institute Co:, Ltd:, Guangdong Zhongchuang Zhijia Scientific Research Co:, Ltd:, Qingdao Haier Technology Co:, Ltd:, Hisense Air Conditioning Co:, Ltd:, Zhuhai Gree Electric Appliances Co:, Ltd:, Panasonic Home Appliances (China) Co:, Ltd:, BSH Electric (Jiangsu) Co:, Ltd:, Philips Home Appliances (China) Investment Co:, Ltd:, Qingdao Guochuang Intelligent Home Appliances Research Institute Research Institute Co:, Ltd:, iFLYTEK Co:, Ltd:, China Mobile (Hangzhou) Information Technology Co:, Ltd:, Weikai Testing Technology Co:, Ltd:, Shenzhen Kaidu Electric Co:, Ltd:, Midea Group Co:, Ltd:, Guangzhou Langguo Electronic Technology Co:, Ltd:, Foshan Nationstar Optoelectronics Co:, Ltd: Co:, Ltd:, Ningbo Aux Electric Co:, Ltd:, Shanghai Chemours Electric Co:, Ltd:, Ningbo Fotile Kitchenware Co:, Ltd:, Zhejiang Shaoxing Supo Haier Home Appliances Co:, Ltd:, Qingdao Haier Whole House Co:, Ltd:, Hisense (Guangdong) Air Conditioning Co:, Ltd:, Midea Group (Shanghai) Co:, Ltd: Co:, Ltd:, Hubei Midea Refrigerator Co:, Ltd:, Zhongshan Kezhuoer Electric Appliance Co:, Ltd:, Zhejiang Maixin Technology Co:, Ltd:, Zhuhai Leitech Technology Co:, Ltd:, Zhuhai Maike Intelligent Technology Co:, Ltd:, Qingdao Hisense Hitachi Air Conditioning System Co:, Ltd:, Guangzhou Hualing Refrigeration Equipment Co:, Ltd:, Guangdong Midea Kitchen Appliance Manufacturing Co:, Ltd:, Hangzhou Xingshuaier Electric Appliance Co:, Ltd:, Qingdao Haier Intelligent Technology R&D Co:, Ltd: Ltd:, Zhejiang Hals Vacuum Container Co:, Ltd:, Bear Electric Appliance Co:, Ltd:, Guangdong Galanz Group Co:, Ltd:, Shenzhen

Intelligent speech refers to the process of intelligent control systems realizing information processing such as sound collection, speech recognition, and semantic understanding through machine perception technology: The program uses natural language understanding and other technologies to analyze, thereby realizing a complete set of computing processes including human-computer dialogue, intelligent analysis and decision-making: Research shows that voice has become an important landing technology for artificial intelligence: The combination of voice and home appliances has created an explosive growth point for the home appliance industry: Home appliances with voice technology have become one of the important interactive entrances to smart homes, but at the same time, smart home device intrusion and user privacy data theft are also a major concern: Incidents such as the use of encrypted messaging systems indicate that there are huge security risks in the smart voice ecosystem: Since traditional controllers mainly focus on hardware and electrical aspects, with the integration of intelligent technology, it is urgent to add corresponding specifications to Adapt to changes, and because smart technology generally uses big data and wireless networks, corresponding regulations are also needed in terms of information security and privacy: Intelligent voice technology relies on the collection, transmission, recognition and understanding of the user's voice to achieve specific functions, such as home appliance control and information query: and identity recognition, and may use voiceprint analysis, voice feature collection, voice content storage, etc:, involving the prevention of Security requirements such as unauthorized access to hardware, preventing unintended use of voice functions, and protecting user privacy data from unauthorized access: This requires corresponding specifications to ensure the safe use of intelligent voice control: General safety technical requirements for intelligent voice controllers

1 Scope

GB/T 43969-2024 sets the general safety technical requirements for intelligent voice controllers, the devices that take a spoken command and act on something physical, a lock, a heater, a cooker, a window, a vehicle function. The safety problem is specific to the modality and is not covered by ordinary appliance safety: speech can be issued by someone outside the room or the house, replayed from a recording, synthesised, or embedded inaudibly in other audio, and a command that would require a deliberate physical act if it were a switch can be given accidentally by a television. The standard sets the requirements that answer that: the identification and authentication of the speaker where a command is consequential, the rejection of replayed and synthetic speech, the confirmation required before a high-risk action, the limits on what may be commanded by voice alone, the local fallback and manual override, the protection of the audio data and of the user's privacy, and the electrical and functional safety requirements, together with the corresponding test methods. It takes effect on 1 November 2024.

This document specifies the classification, technical requirements and test methods for the general safety of intelligent voice controllers: This document applies to all types of household and similar electronic products with intelligent voice control functions covered by the GB/T 14536 series of standards Security assessment of the voice controller (hereinafter referred to as the "voice controller"):
