System for speech recognition and correction, correction device and method for creating a lexicon of alternatives
First Claim
1. A speech recognition and correction system which comprises at least one speech recognition device (1) to which a spoken text (GT) can be fed, it being possible for said spoken text to be transcribed into a recognized text (ET), and a correction device (3) for correcting the text (ET) recognized by the at least one speech recognition device (1), said correction device being connected to the at least one speech recognition device (1) via a data network (2) for the transmission of the recognized text (ET) and where appropriate of the spoken text (GT), characterized in that the correction device (3) has a lexicon of alternatives (23) which contains word parts, words and word sequences that can be displayed (22) by the correction device (3) as alternatives to individual word parts, words and word sequences of the recognized text.

- 2. A correction device for correcting a text recognized by a speech recognition device, characterized in that a lexicon of alternatives (23) is stored in the correction device (3), which lexicon of alternatives contains word parts, words and word sequences that can be displayed (22) by the correction device (3) as alternatives to individual word parts, words and word sequences of the recognized text.
- 7. A method of creating a lexicon of alternatives for determining data record entries for a lexicon of alternatives (23) for the correction of recognized text (ET) which has been transcribed from spoken text (GT) by a speech recognition device (1), characterized in that sources of knowledge (12, 13) that are independent of the speech recognition device (1), in particular text files specific to the field of application, such as medical or legal texts, or confusion statistics compiled from a large number of corrected texts (KT) and associated recognized texts (ET) generated by speech recognition devices, are examined with respect to text elements such as word parts, words or word sequences that can be confused with one another, and such text elements that can be confused with one another are put together as alternatives in a data record entry of the lexicon of alternatives (23).
