TL;DR: In this paper, the authors investigated the relationship between verbal ability and speech reading and found that lexical access speed was related to speech reading performance, but not directly related to vocabulary size.
Abstract: Eighteen hearing-impaired subjects participated in the present study. The purpose was to investigate one general question: The nature of the relationship between verbal ability and speechreading. Verbal ability was assessed by two types of measure: a test of vocabulary size, and four tests of lexical access speed. The results demonstrated that lexical access speed was related to speechreading performance. Vocabulary size was not found to be directly related to the speechreading criterion; rather, its influence was in an indirect fashion via its relation to lexical access speed. It was concluded that lexical access speed could be used as a diagnostic tool, such that when an individual demonstrates lexical access that is unreasonably slow, it could be taken as an indication to suggest that rehabilitation programs should emphasize alternatives to speechreading. A general implication of the present results is that absence of relation between a predictor variable and the speechreading criterion does not necess...

TL;DR: Tactiling is generally better than speechreading alone, and the results from the test given by the familiar speaker are better than with the unfamiliar speaker, indicating that the method is worth pursuing as a communication system for the deafened adults.
Abstract: The purpose of this study was to find out whether deafened adults can take advantage of the extra information in speechreading given by the vibrational and motional patterns picked up by placing a hand on a speaker's throat and shoulder, and how valuable this tactile supplement is as a support system for speechreading. We have named this method —speechreading with tactile supplement — tactiling. Eight deafened adults participated in the study, conducted with a pre-test/post-test control group design. The experimental and the control groups took speechreading classes together. The experimental group received additional individual training in tactiling during six 1 h lessons. Both the experimental and the control groups were tested, before and after training, first by a familiar person and thereafter by an unfamiliar person. The results demonstrated two significant main effects. Tactiling is generally better than speechreading alone, and the results from the test given by the familiar speaker are better tha...
