This is a response to Patti Raswant's blog post as well as the DBC requests.
There seems to be some confusion about what total communications and simultaneous are. I was brought up via the oral method as a child, but then started using simultaneous communications later on. I often use sim comm when I'm with other deaf and with those who don't use or don't know sign language.
Observe these URLs;
Simultaneous communications, according to what I was told and experienced multiple times, is the use of speech/lipreading and sign at the same time. Total Communications is the use of all means of communications whenever. Meaning, in the course of the day, someone goes through speech therapy, and then at home, uses sign language. It's not time-sensitive.
