Character recognizing and translating system and voice recognizing and translating system

A voice recognizing and translating system for recognizing a detected voice and translating the voice into words or sentences, comprising:

• a voice memory which stores voice data representing the detected voice;
• a noise deletion unit which removes data corresponding to noise from the voice data;
• a sound data base which stores the data from which the noise is removed by said noise deletion unit;
• a first sound analysis unit which extracts the feature of a voice corresponding to the voice data stored in said sound data base;
• a model learning unit which creates an acoustic model from the analysis result of said first sound analysis unit;
• an acoustic model storing unit which stores the acoustic model;
• a second sound analysis unit which extracts the feature of the voice corresponding to data which are obtained by removing the data representing noise from the voice data of the voice;
• a voice collating unit which collates the voice data obtained by said second sound analysis unit with the data of the acoustic models stored in said acoustic model storing unit to recognize the detected voice;
• and
• a translation unit which translates words or sentences which are composed of the detected voice recognized by said voice collating unit;
• wherein said voice recognizing and translating system further comprises a stationary-mount information equipment having an external storage device, and a portable information equipment which is detachably connected to said stationary-mount type information equipment, and wherein said sound data base, said first sound analysis unit and said model learning unit are provided to said stationary-mount-type information equipment, said external storage device containing said sound data base, and all remaining constituent elements being provided to said portable information equipment.

A voice recognizing and translating system for removing noise data corresponding to noise from voice data representing an input voice so as to extract a feature of the voice corresponding to the voice data from which the noise data is removed and a feature of the noise corresponding to the noise data, creating an acoustic model on the basis of the feature of the voice and the feature of the noise, recognizing a newly input voice to be translated on the basis of the acoustic model, and translating words or sentences constituting the recognized voice, including:

• a second sound analysis unit which extracts a feature of the newly input voice to be translated and extracts a feature of noise of the newly input voice;
• a voice collating unit which collates the feature of the newly input voice extracted by said second sound analysis unit with the acoustic model corresponding to the feature of the noise extracted by said second sound analysis unit to recognize the newly input voice, wherein a different acoustic model is created for a feature of the input voice indicative of a same input voice if the feature of the noise differs;
• and
• a translation unit which translates words or sentences constituting the newly input voice recognized by said voice collating unit.
