do the display info audible for blind people

Hi Guys
I need to become the information in my display LCD1602A audible for blind people.
We are Ham radio and it will be very useful for blind people whose can not see the frequency displayed.
I was learning how to use the "Serial.println(data)", maybe some one can help me to complete this project.
Please let me know any concern.
Thank you in avance
