Fish can hear sounds, including human voices, but not in the same way that humans do. While they don't have ears like ours, they have a system of sensory organs called the lateral line that detects vibrations in the water.
These vibrations can be caused by a variety of things, including the movement of other fish, the flow of water, and even human voices.
Fish can also hear sounds through their swim bladder, which acts as a resonating chamber, amplifying sound waves.
While fish can detect the sounds of human voices, they likely don't understand the meaning of the words. They may react to the vibrations themselves, or to the changes in water pressure that human voices can create.
Some studies suggest that fish may be able to learn to associate certain sounds with specific events, such as feeding time.
However, this is still an area of ongoing research.
In conclusion, fish can hear human voices, but they likely don't understand the words. They respond to the vibrations and pressure changes created by the sounds.
