SPEECH VISUALIZATION SISTEM AS A BASIS FOR SPEECH TRAINING AND COMMUNICATION AIDS

One receives much more information through a visual sense than through a tactile one. However, most visual aids for hearing-impaired persons are not wearable because it is difficult to make them compact and it is not a best way to mask always their vision.

Generally it is difficult to get the integrated patterns by a single mathematical transform of signals, such as a Foruier transform (Liberman et al., 1968). In order to obtain the integrated pattern speech parameters should be carefully extracted by an analysis according as each parameter, and a visual pattern, which can intulitively be understood by anyone, must be synthesized from them. Successful integration of speech parameters will never disturb understsnding of individual features, so that the system can be used for speech training and communication.
