Voice Detection: AI Makes Baby Care Intelligent

3 min readApr 16, 2023


In recent years, the baby industry has developed into a deep-water area. The increase in capital has made the baby market more and more standardized and scaled, and the development route has become clearer and clearer.

The three core trends of investment and financing in the baby industry are: content entrepreneurship, artificial intelligence, and new retail for mothers and babies. Artificial intelligence has long been favored by market players, and baby-empowering AI has become an inevitable result of the mature development of the baby industry.

Babies (0–3 years old) are characterized by the inability to accurately express their intentions in words, and their actions are highly uncertain and dangerous. The application of artificial intelligence technology in the baby product and service industry is of great value. It not only allows babies to receive more humane care, but also reduces the pressure on parents to a certain extent.

Specifically, artificial intelligence for babies mainly includes face recognition and voice detection technologies.

Face Recognition

Several AI companies have developed artificial intelligence baby monitors to keep an eye on babies. Such camera systems collect data on babies around the clock and alert parents if they spot signs of crying, vomiting or distress.

Voice Detection

Speech detection also has important implications for children’s medical research. Because infants do not understand expressions, “self-report”, an indicator for judging diseases and taking treatment measures, is usually difficult to obtain in the field of pediatrics. By studying the baby’s voice and other external manifestations, AI can be used to obtain more accurate positioning, which is conducive to the symptomatic treatment of pediatrics.
