Speech and Language Technology for Disabled Persons
Patients with cochlear implants must be trained to associate the electric signal with its linguistic significance. Several techniques have been developed. Their success has been limited since: 1) patients use upper level knowledge to predict what is said, and 2) content is not lexically and semantically balanced (and adapted to signal processing). And present techniques presume most patients will remain lipreading-dependant. The training techniques here make patients use "low level" hearing instead of prediction and progressively increase lexicon and semantic content (and task difficulty). Patients start with lipreading and gradually become independent of it. Assessment of progress is compatible with training and the final goal. These exercises are independent of training, and also assess the patient's "low-lever processes without higher level "interference", using known vocabulary and familiar subjects. The method was tested by several multichannel implant patients. Training and assessment techniques are described and results discussed.
