China's Baidu looks to patent AI system to decipher animal sounds

Ever wished you could understand what your cat is trying to tell you? A Chinese tech company is exploring whether it's possible to translate those mysterious meows into human language using artificial intelligence. Baidu, owner of China's largest search engine, has filed a patent with China National Intellectual Property Administration proposing a system to convert animal vocalisations into human language, according to a patent document published this week.

Baidu’s proposed system goes beyond just analyzing vocalizations like meows or barks. It incorporates multimodal data vocal sounds, behavior, and even physiological signals (like heart rate or movement), which allows for a much richer and more accurate analysis of an animal’s emotional state. This kind of cross referencing is critical because animals, especially cats, often use subtle cues to communicate that may not be obvious in sound alone. 

Mapping emotional states to human language via AI could revolutionize pet care, training, and companionship. 

• A pet owner might receive a notification like “Your cat is feeling anxious” or “Your dog wants attention.” 
• Veterinarians could use it to identify stress or pain in animals that can’t vocalize distress clearly.
• Animal shelters could improve animal welfare and adoption success rates by understanding individual emotional profiles. 

Of course, as Baidu notes, it's still in the research phase. There are major challenges ahead 

• Species variation (not all animals "speak" the same way). 
• Data diversity (a large dataset is needed for reliable results). 
• Semantic accuracy (translating emotion into meaningful, actionable language).
