Abstract: A system includes a first user device configured to perform captioning session operations, a call-assistant (CA) device remote from the first user device, and a remote relay server separate from the CA device. The relay server initiates a captioning process, receives, from the first user device, a request to initiate a captioning session, establishes the session, assigns the session to the CA, receives first audio data from the first user device derived from a second user device, directs the first audio data to the CA device, receives, from the CA device, second audio data related to the first audio data and derived from CA speech, accesses an ASR engine trained to the CA voice, generates captioned text including a transcription of the second audio data, generates screen information including the transcription, directs the screen information to the CA device, and directs the captioned text to the first user device.

Abstract: A method and system to transcribe communications the method comprising the steps of obtaining an audio message originating at a first device during a voice communication session between the first device and a second device, providing the audio message to a first speech recognition system to generate a first transcript of the audio message, directing the first transcript to the second device, in response to obtaining an indication that indicates a quality of the first transcript is below a quality threshold, using a second speech recognition system to generate a second transcript based on the audio message while continuing to provide the audio data to the first speech recognition system to generate the first transcript and, in response to occurrence of an event that indicates the second transcript is to be directed to the second device, directing the second transcript to the second device instead of directing the first transcript.

Abstract: A method to transcribe communications includes the steps of obtaining a voice signal originating at a first device configured for verbal communication with a second device and providing the voice signal to an automated speech recognition system configured to transcribe the signal. Before determining a final transcription, the method obtains a first hypothesis transcription including one or more first words determined to be a transcription of at least a first portion of the voice signal and a second hypothesis transcription including a plurality of second words determined to be a transcription of at least a second portion of the voice signal that includes the first portion of the voice signal, determines one or more consistent words included in both hypothesis transcriptions, and in response, transmits the consistent words to the second device for presentation before the final transcription of the voice signal is provided to the second device.

Abstract: A captioning method for presenting captions to an assisted user (AU) during communication with a hearing user (HU) where the assisted user uses a captioned device and the hearing user uses a hearing user's device to facilitate the communication, the captioned device including a display screen and a speaker for presenting captions and broadcasting the hearing user's voice signals, respectively, the method comprising the steps of during an ongoing call between the AU and the HU, using an automated speech recognition (ASR) engine to generate initial ASR captions associated with the HU's voice signal, assessing at least one caption quality factor associated with prior initial ASR captions generated during the ongoing call, delaying broadcast of HU voice signal to the AU and based on the at least one caption quality factor, adjusting a duration of the HU voice signal broadcast delay.

Abstract: A system for providing voice-to-text captioning service comprising a relay processor that receives voice messages generated by a hearing user during a call, the processor programmed to present the voice messages to a first call assistant, a call assistant device used by the first call assistant to generate call assistant generated text corresponding to the hearing user's voice messages, the processor further programmed to run automated voice-to-text transcription software to generate automated text corresponding to the hearing user's voice messages, use the call assistant generated text, the automated text and the hearing user's voice messages to train the voice-to-text transcription software to more accurately transcribe the hearing user's voice messages to text, determine when the accuracy exceeds an accuracy requirement threshold, during the call and prior to the automated text exceeding the accuracy requirement threshold, transmitting the call assistant generated text to the assisted user's device for display to the assisted user and subsequent to the automated text exceeding the accuracy requirement threshold, transmitting the automated text to the assisted user's device for display to the assisted user.
