Simultaneous Communication, known as SimCom, uses sign language and voice to communicate a message in both languages at the same time. SimCom is used by hearing and hard of hearing and some Deaf people. It is impossible to clearly present ASL and English at the same time. SimCom compromises both languages, but eliminates the need for an interpreter and allows the speaker more control over the message. Even many skilled signers can find SimCom difficult to use. Here are some tips for more effective use of SimCom, with emphasis on the signed message.
While preparing the message, consider what it would look like if presented only in ASL.
Consider simple English words and sentence structure for voicing. Avoid hard-to-sign words, idioms, and phrases.
As you prepare for SimCom, consider which parts of the message may be most difficult to communicate clearly in both languages. You may need to voice different words than what normally are associated with a particular sign. It also may be necessary to sign something first, then voice the meaning afterward. Practice signing and voicing those sections until you are confident it is the most clear in both languages.
Present the message primarily in Sign Language using mostly ASL structure. This will help avoid signing English words. Use simple English sentences to voice what you sign. Be sure to say what you sign, not sign what you say.
Be aware of and avoid the tendency to create the message in English and only attach signs to your words.
There are times when SimCom is the preferred method of communication. When it is, practice, practice, practice!
