Title: Method of recognizing alphanumeric strings spoken over a telephone network
Inventor: SCHALK THOMAS B
IPC: H04M3/487
Filed: 1991-05-14
Abstract: The present invention describes a method for recognizing alphanumeric strings spoken over a telephone network wherein individual character recognition need not be uniformly high in order to achieve high string recognition accuracy.      Preferably, the method uses a processing system having a digital processor, an interface to the telephone network, and a database for storing a predetermined set of reference alphanumeric strings.      In operation, the system prompts the caller to speak each character of a string, beginning with a first character and ending with a last character. Each character is then recognized using a speaker independent voice recognition algorithm. The method calculates recognition distances between each spoken input character and the corresponding letter or digit in the same position within each reference alphanumeric string. After each character is spoken, captured and analyzed, each reference string distance is incremented and the process is continued, accumulating distances for each reference string, until the last character is spoken. The reference string with the lowest cumulative distance is then declared to be the recognized string.

Abstract: A converted feed gas comprising a first portion of the SO2-enriched stripper gas is formed. A conversion gas comprising SO3 and residual SO2 is formed by passing the converted feed gas through a plurality of catalyst beds in series, the plurality comprising at least 2 and no greater than 4 catalyst beds. A  second portion of the SO2-enriched gas is introduced into at least one catalyst bed which is downstream of the most upstream catalyst bed in the plurality to fortify the SO2 concentration in the gas fed to the downstream bed. The present invention is also directed to a process for making sulfuric acid and/or ileum from a source gas comprising SO2. A conversion gas comprising SO3 and residual SO2 is formed by passing the SO2-enriched stripper gas through a plurality of catalyst beds in series. The conversion gas is combined with water vapor to form an acid product gas comprising: (a) sulfuric acid formed by a gas phase reaction between SO3 from the conversion gas and water vapor, thereby generating the heat of formation of sulfuric acid in the gas phase; (b) SO3; and (c) SO2. Heat energy from the gas phase heat of formation of sulfuric acid is recovered by transfer of heat from the acid product gas to steam or feed water in an indirect heat exchanger. The cooled acid product gas is then contacted with liquid sulfuric acid in an SO3 absorption zone to form additional sulfuric acid and/or oleum and an SO3-depleted gas comprising SO2.
