Voice guidance is a technology that provides spoken instructions to help users navigate various tasks or environments. It is commonly used in devices like smartphones, GPS systems, and navigation apps to assist users in reaching their destinations or completing specific actions without needing to look at a screen. This feature is particularly beneficial for individuals with visual impairments or those who prefer auditory information. By using voice guidance, users can receive real-time updates and directions, enhancing their overall experience and making technology more accessible to everyone.
