Abstract: A method for comparing text in a first file to text in a second file. The method includes segmenting text in the first and second files to one word per line; comparing the segmented versions of the versions of the first and second files on a line by line basis; creating a result file using the segmented version of the first file; and augmenting the result file with indication of error using a sandwiching technique. This sandwiching technique includes identifying correct segments that are immediately adjacent any differences identified by comparing the segmented versions of the first and second files on a line by line basis toward sandwiching the erroneous segments between correct segments. Said method incorporates video monitor (26), keyboard (24), and mouse (23), along with microphone (25) and digital recorder (14) for implementing the invention.

Abstract: A system for substantially automating transcription services for multiple users (10, 11, 12) including a manual transcription station (50), speech recognition program (40) and a routing program (200). A uniquely identified voice dictation file is generated from a user and—based on the training status—routes the voice dictation file to a manual transcription station and speech recognition program. A human transcriptionist creates transcribed files for each voice dictation file. The speech recognition program creates written text for each dictation file if the training status is training or automated. If the training status of the current user is enrollment or training, a verbatim file is manually established and the speech recognition program is trained with an acoustic model using the verbatim and voice dictation files. The transcribed file is returned to the user if the training status is enrollment or training or written text is returned if the status is automated.

Abstract: A system for automating transcription services for one or more users. This system receives a voice dictation file from a current user, which is automatically converted into a first written text based on a set of conversion variables. The same voice dictation file is automatically converted into a second written text based on a second set of conversion variables. The first and second sets of conversion variables have at least one difference, such as different speech recognition programs, different vocabularies, and the like. The system further includes a program for manually editing a copy of the first and second written text to create a verbatim text of the voice dictation file. This verbatim text can be delivered to the current user as transcribed text. The verbatim text can also be fed back into each speech recognition instance to improve the accuracy of each instance with respect to the human voice in the file.

Abstract: A system and method for improving the accuracy of a speech recognition program. The system is based on a speech recognition program that automatically converts a pre-recorded audio file into a written text. The system parses the written text into segments, each of which can be corrected by the system and saved in a retrievable manner in association with the computer. The standard speech files are saved towards improving accuracy in speech-to-text conversion by the speech recognition program. The system further includes facilities to repetitively establish an independent instance of the written text from the pre-recorded audio file using the speech recognition program. This independent instance can then be broken into segments and each erroneous segment in said independent instance replaced with the corrected segment associated with that segment. In this manner, repetitive instruction of a speech recognition program can be facilitated.

Abstract: A system and method for quickly improving the accuracy of a speech recognition program. The system is based on a speech recognition program that automatically converts a pre-recorded audio file into a written text. The system parses the written text into segments, each of which is corrected by the system and saved in an individually retrievable manner in association with the computer. The standard speech files are saved towards improving accuracy in speech-to-text conversion by the speech recognition program. The system further includes facilities to repetitively establish an independent instance of the written text from the prerecorded audio file using the speech recognition program. This independent instance can then be broken into segments and each segment in said independent instance replaced with an individually retrievable saved corrected segment associated with that segment. In this manner, repetitive instruction of a speech recognition program can be facilitated.

Abstract: A system for substantially automating transcription services for multiple voice users including a manual transcription station, a speech recognition program and a routing program. The system establishes a profile for each of the voice users containing a training status which is selected from the group of enrollment, training, automated and stop automation. When the system receives a voice dictation file from a current voice user based on the training status the system routes the voice dictation file to a manual transcription station and the speech recognition program. A human transcriptionist creates transcribed files for each received voice dictation files. The speech recognition program automatically creates a written text for each received voice dictation file if the training status of the current user is training or automated.

Abstract: A day/night vehicle rearview mirror assembly comprises a casing carrying a prismatic mirror, the casing being pivotally mounted on a mounting plate. Preferably, the casing and mirror are driven between a full reflectance position and partial reflectance position by a rack and pinion assembly having interengaging gear teeth extending between a d.c. motor operated drive shaft and a portion of the casing. Alternately, a friction coupling extends between the drive shaft and casing. A noise and vibration reducing coupling are provided in the drive shaft while appropriate glare sensing circuitry and/or switches control operation of the reversible motor and, thus, the reflectance position of the mirror.

Abstract: The present invention is concerned with apparatus for selectively opening and closing doors to vacuum bodies, for example the bodies of industrial vacuum loaders and cleaners and the vacuum bodies used in pneumatic sewer cleaners.

Abstract: A hose reel apparatus is disclosed which permits proper winding and unwinding of a hose, for example the water hose of a sewer cleaning machine. The apparatus includes a reel, preferably a power driven reel, for winding and unwinding a hose and a series of rollers coupled together by links. The rollers are positioned on the outside circumference of the hose windings in such a manner that a radial force is exerted on the hose causing hose windings to remain tight against the core of the reel. The preferred embodiment also includes means for holding the rollers against the windings whether the hose is fully wound, fully unwound or partially unwound, i.e. regardless of the circumference of the hose windings. This latter feature is accomplished by providing spring means coupled to the rollers and links to urge the rollers into contact with the hose.
