Mobile Phone: New device gives hearing-impared people the ability to roam freely

For the hearing impaired, using the phone is never an easy task.

Most devices, such as a TTY teletypewriter or TDD machine, are bulky keyboard terminals that use a telephone line to establish a text connection with others using a similar machine.

The problem with TTYs and TDDs is that they are heavy, can only be used on one phone and are not portable.

But a deaf couple in Fort Worth is trying to solve that problem.

Krown Manufacturing, co-founded by Sidney and Barbara Ander, is taking the technology used in cellular phones and pages to create a smaller, portable device called the Pocket Speak and Read VCO.
