This activity has big use nowadays. First of all, due to such conversion we don’t need to focus on reading, because while listening we can also do other activities. It is more comfortable with text to speech mobile phones, because with them while listening we can also run. Secondly, this technology helps people with a disability such as blindness to learn and acquire knowledge. Thanks to text to speech mobile phones they have a possibility to learn whenever and wherever they want. This is very good for them, because they have equal rights for education as non-disabled people and thanks to the opportunity of getting higher education they can work as well as average people and feel needed as they do.
