Abstract: A voice transcription system employing a speech engine to transcribe spoken words, detects the spelled entry of words via keyboard or voice to invoke a database of common words attempting to complete the word before all the letters have been input. This database is separate from the database of words used by the speech engine. A voice level indicator is presented to the operator to help the operator keep his or her voice in the ideal range of the speech engine.

Abstract: An editing system for real-time remote transcription, such as may be used by deaf or hearing impaired individuals, displays transcribed text on a screen prior to transmission so that a human call assistant may identify words being held in a buffer by their spatial location on the screen to initiate a correction of those words either through speech or text entry.

Abstract: A training method and apparatus to train a call assistant to operate a telephone relay system for the hearing impaired that uses a re-voicing technique to produce near real-time transcription of a telephone conversation for display on a caption telephone or other device. The invention simulates an actual relay call as realistically as possible and produces a report on the skill of the particular call assistant being trained.

Abstract: A unified TDD and telephone incorporate intelligent mode switching to permit users of either device to use the integrated unit with the other features remaining largely invisible by sensing various signals including the removal of the handset or the turning on and off of the TDD device to determine the likely mode of a transmission and the detection of text to determining the likely mode of the receive text. This intelligent mode conversion includes a voice carryover mode in which text and voice may both be transmitted.

Abstract: A combined telephone AED simply integrates the function of a telephone and an alphanumeric entry device required for alphanumeric paging into a single unit by making use of the handset cradle switch to reset the unit from page mode to telephone mode whenever the handset is lifted. Paging operation is simplified through pre-stored entries in a directory giving both voice and paging numbers with the appropriate number being identified by the previously selected mode of the operation of the unit. Special purpose paging and speed dial buttons serve the combined function of identifying a mode of operation and initiating a search of the directory to reduce the number of keystrokes required of a user during typical operation.

Abstract: A telecommunications device automatically detects the code used by a second telecommunications device to which the devices are linked to transmit and receive therebetween. After the telecommunications device has been set to transmit and receive in code which has been detected, the telecommunications device continues to interrogate the second telecommunications device for a more optimal code (usually a code with higher transmission and receiving speeds) that is common to both devices.
