Abstract

Abstract An electronic recording and playback aid for use in stenographic reporting, by means of which the speakers'' voices are recorded and later played back to prepare a typewritten transcript of their words. Identification of which speaker is speaking at a given time is enabled by a unit associated with the recording apparatus and having a key for each speaker, the court reporter or attendant operating the appropriate corresponding key when a given speaker is speaking. Operation of the key applies a particular frequency of signal to a channel or track separate from that in which the speech is recorded, the frequency or tone continuing throughout the speech by that speaker, until a different key for a different speaker is operated. A light associated with each key is also automatically turned on when that key is operated, so that the operator can assure himself that the proper key is operated. When the recording is later played back, the particular speaker''s identification signal is automatically detected and used to turn on the light associated with the corresponding speaker''s key, while the speaker''s words are also being played back. This enables the operator on playback to start at any point on the tape with the speaker automatically identified by the light associated with his key, and without any interference with the sound of the recorded words.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 149 words
In a method for recording voices of a plurality of speakers and for enabling later identification of each voice with the proper corresponding speaker, the steps of: producing voice signals representative of said voices and recording said voice signals upon a sound storage medium; producing a plurality of identifiably different voiceidentification signals, one for each of said speakers; and separately recording on said sound storage medium, continuously througout each time one of said voice signals produced by one of said speakers is being recorded, that one of said different voice-identification signals corresponding to the voice then speaking, in a manner to permit electrical separation of said voice-identification signals from said recorded voice signals upon later reproduction of signals on said storage medium, thereby to enable continuous identification of the speaker during reproduction of each voice signal without the interference with the sound of each voice by the voiceidentification signals.
Claim 2
Dependent Claim 149 words
In a method for recording voices of a plurality of speakers and for enabling later identification of each voice with the proper corresponding speaker, the steps of: producing voice signals representative of said voices and recording said voice signals upon a sound storage medium; producing a plurality of identifiably different voiceidentification signals, one for each of said speakers; and separately recording on said sound storage medium, continuously througout each time one of said voice signals produced by one of said speakers is being recorded, that one of said different voice-identification signals corresponding to the voice then speaking, in a manner to permit electrical separation of said voice-identification signals from said recorded voice signals upon later reproduction of signals on said storage medium, thereby to enable continuous identification of the speaker during reproduction of each voice signal without the interference with the sound of each voice by the voiceidentification signals.
Claim 3
Dependent Claim 28 words
A method as claimed in claim 1 wherein said recording comprises recording on two different storage tracks, one for said voice signals and one for said voice-identification signals.
Claim 4
Dependent Claim 33 words
A method as claimed in claim 1 wherein said recording comprises recording on different storage tracks, at least one for said voice signals and at least one other track for said voice-identification signals.
Claim 5
Dependent Claim 30 words
A method as claimed in claim 1 wherein said producing of voice-identification signals comprises producing oscillations in different frequency ranges, each range corresponding to a particular one of said speakers.
Claim 6
Dependent Claim 22 words
A method as claimed in claim 1 comprising producing a visual indication of which voice-identification signal is being recorded at any time.
Claim 7
Dependent Claim 45 words
A method as claimed in claim 1 comprising reproducing said voice signals and their corresponding voice-identification signals from said storage medium, and discriminating among said reproduced voice-identification signals to produce a visual indication of the identity of the speaker whose voice is being played back.
Claim 8
Dependent Claim 114 words
A method as claimed in claim 1 wherein said producing of said voice-identification signals compriSes producing oscillations in different frequency ranges, each range corresponding to a particular one of said speakers, and said method comprising reproducing said voice signals and their corresponding voice-identification signals from said storage medium, and discriminating among said reproduced voice-identification signals to produce a visual indication of the identity of the speaker whose voice is being played back, said discriminating comprising applying said voice identification signals to a plurality of frequency-selective filter means each passing voice-identification signals in only one of said ranges, and producing a different visual display depending upon which of said filter means is passing voice-identification signals.
