Oregon Relay Service not only offers relay services for deaf or hard-of-hearing consumers but also for consumers with a speech disability. People with hearing and speech disabilities use the phone like everyone else – to find out about a product, make an appointment, reach a teacher, call a parent with a birthday party invitation, or simply to be neighborly.


Two services that are available for callers with a speech disability are:



The HCO user types his/her conversation directly to the TTY user.  HCO users can listen while the Relay Operator is reading/voicing the TTY user's typed reply message.

711 or 800-735-2900

Oregon Relay also offers two additional HCO features; HCO to TTY and HCO to HCO services.

711 or 800-735-2900

HCO users can contact other HCO users through Oregon Relay. The Relay Operator will voice to both parties what is typed on each other's TTY.

711 or 877-735-7525

Speech-to-Speech (STS) allows a speech-disabled person to voice his/her conversation. A specially trained STS operator repeats the words of the person with a speech disability or synthesizer output to the other person. No special equipment is needed to use this service.


This feature makes call set-up easier for STS users.
