Counteracting Adverse Speaking Environments: A Model for HeO2 Speech

There are many situations where adverse speaking conditions operate to prevent good message transfer. However, most research on the factors which degrade reasonably good speech intelligibility have focused on only a single form of disruption. The problem is that, until virtually all (multiple) distortions/degradations have been studied, there are a number of situations where not even marginal communication is reasonably possible. A model is proposed where multiple remedies are applied simultaneously. The approach attempts to provide acceptable speech intelligibility even where the nature of the distorting factors are not fully understood. An example is given to illustrate how the model would work; it involves speech uttered in the deep diving situation where ambient pressure is great and exotic gas mixtures (HeO2) are used. The model in this case, involves the development of a speech lexicon, articulatory modification of speakers output, a variety of electronic processors and the training of the listeners/decoders
