The California STS service enables people whose speech is difficult for others to understand to communicate by telephone. With this service, you can make calls by yourself, independent of the availability of your assistant or caregiver. When you make a call using STS, a specially-trained STS Communications Assistant (CA) will be on the line with you to assist you during your call. The CA can repeat what you are saying for the person on the other end. You and the person on the phone with you can decide how much of your speech will be repeated: only particularly difficult words or every word you say. No special equipment is needed. You may use your own voice or a Speech Generating Device (SGD). People can also make a call to you through the STS Relay Service. There is no charge to use this STS service; you pay only for the cost of the call from your phone service provider, if any. The California STS service is part of the California Relay Service (CRS), a program of the California Public Utilities Commission (CPUC).

The STS service can be used by anyone whose speech is difficult for others to understand on the phone and would like to have assistance during their call. This service may be especially beneficial for people who have had a stroke, a laryngectomy, who stutter, have Parkinson’s disease, Lou Gehrig’s, Multiple Sclerosis, Cerebral Palsy, brain injury, or any other condition that causes others to have difficulty understanding the user’s speech on the phone. People can also make a call to you through the STS service, e.g., family members, friends, medical professionals or businesses.
Let the CRS relay providers know in advance how you want your STS call handled – by 711 Choice or by a Customer Profile:
By registering your 711 Choice you can pre-select from the following options:
- Type of Communication – Speech-to-Speech
- Preferred Language – English or Spanish
After registering your choices, all your calls will be routed automatically to a trained STS CA and in your preferred language.
You can also let the CRS Providers know exactly how you want your calls handled by setting up a Customer Profile. That includes, but is not limited to:
- Conversation related information (e.g.,a customized explanation of STS service to be provided to the persons you call or a standard message from you that can be left on answering machines)
- Call setup-related information (e.g., your preferred long distance provider; a list of most frequently called names and numbers; when and where you can be reached if someone tries to contact you through STS relay)
Even if you don’t have a Customer Profile, you can give the CA instructions before (s)he places your call. For example:
- You can ask the STS CA to re-voice everything you say, to only re-voice when the person you are talking to doesn’t understand, or not to re-voice anything unless you ask for assistance.
- Before the actual call is placed, you can dictate a message to the CA to be used during the conversation.
- You can ask the CA to retain parts or all of a message for use in future phone calls.
