We use the viral video to raise a serious question: can we understand animal talk? ‘Bowlingual’ detects a dog’s emotions by analysing a bark’s sound waves. Students look at emerging research to decide what else the technology can do. Can we translate the sound waves into human speech?
- Apply knowledge about sound waves
- Construct an argument supported by evidence and reasoning to support the claim that a device can interpret dog barks
