Abstract: A captioning system comprising a processor and a memory having stored thereon software such that, when the software is executed by the one or more processors, the system generates text captions from speech data, including at least the following, receiving, from a hearing user's (HU's) device, an HU's speech data, generating, at the one or more hardware processors, first text captions from the speech data using a speech recognition algorithm, automatically determining, at the one or more processors, whether the generated first text captions meet a first accuracy threshold and when the first text captions meet the first accuracy threshold, sending the first text captions to an assisted user's (AU's) device for display, when the first text captions do not meet the first accuracy threshold, generating, at the one or more processors, second text captions from the speech data based on user input to the speech recognition algorithm from a call assistant and sending the second text captions to the AU's device for display.

Abstract: A method to transcribe communications includes the steps of obtaining a plurality of hypothesis transcriptions of a voice signal generated by a speech recognition system, determining consistent words that are included in at least first and second of the plurality of hypothesis transcriptions, in response to determining the consistent words, providing the consistent words to a device for presentation of the consistent words to an assisted user, and presenting the consistent words via a display screen on the device, wherein a rate of the presentation of the words on the display screen is variable.

Abstract: A system and method for use with an assisted user's communication device that includes a display. The method includes providing a user communication device including a processor that is programmed to perform the step of, upon disconnection of an emergency call to a hearing user in which a captioning service has provided text transcription of voice messages from the hearing user, maintaining a link to the captioning service for a predetermined period of time. The processor also is programmed to perform the step of recognizing the call as an emergency call upon placement of the call, and the captioning service is automatically initiated upon the processor performing that recognition.

Abstract: A method and system for providing captioned telephone service, the method comprising the steps of, initiating a first captioned telephone service call, during the first captioned telephone service call, creating a first set of captions using a call assistant, simultaneous with creating the first set of captions using a call assistant, creating a second set of captions using an automated speech recognition engine, comparing the first set of captions and the second set of captions using a scoring algorithm based on errors between the first and second sets of captions to generate a score for the second set of captions, in response to the score being within a predetermined threshold range, continuing the call using only the automated speech recognition engine to generate text and in response to the score being outside of the predetermined threshold range, continuing the call using a call assistant to generate captions.

Abstract: A system and method for use with an assisted user's communication device that includes a display and a speaker, the method comprising the steps of providing a processor programmed to perform the steps of, upon placement of an emergency call to a hearing user, recognizing the call as an emergency call, automatically initiating a captioning service to provide text transcription of voice messages from the hearing user and providing some indication to the assisted user that captioning has been automatically commenced and, upon placement of a non-emergency call, only starting the captioning service after a request for the captioning service from the assisted user is received.

Abstract: A system and method, the method comprising receiving, at a processor, an hearing user's (HU's) voice signal from an HU participant during a first call, wherein the first call is a communication across a communication network, the processor programmed to perform the steps of, examining at least a portion of the voice signal to determine an identity of the HU, identifying a voice model associated with the identity of the HU, wherein the voice model comprises a plurality of rules, and further wherein each of the plurality of rules is a rule for transcribing a word in the HU voice signal into text and generating a text output, wherein the text output is a transcription of a plurality of words identified in the HU voice signal, and further wherein at least one of the plurality of words identified is identified using at least one rule of the plurality of rules.
