Abstract:
1. A method of data entry by voice under adverse conditions for efficient and robust form filling, the method comprising: communicating an input utterance from a speaker to a speech recognition means; spotting a plurality of spotted words of at least two recognized spoken words within the input utterance, wherein the spotted words form a phrase containing at least one of field-specific values or commands; obtaining blocks of text from input utterances separated from other input utterances by natural speech pauses, exactly one block of text per input utterance; determining whether a block of text contains recognized values as opposed to commands; populating a license plate number field of a form by concatenating, based on a sequence of input utterances from which the blocks of text are obtained, blocks of text determined to contain recognized values; echoing blocks of text back to the speaker via a text-to-speech system, wherein audio feedback echoing the blocks of text is performed upon interpretation of each input utterance, and a sequence of recognized values echoed in the audio feedback reflects a sequence of spotted words within the input utterance from which the recognized values are obtained; rejecting unreliable or unsafe inputs for which a confidence measure is found to be low; and maintaining a dialogue history enabling editing operations and correction operations on all active fields.
