Abstract
Abstract An audio editor displays not only the electrical waveform (34) of an audio or audio-visual recording being edited, but also the text (36) of speech material included in the recording, the text being generated automatically from the recording by a speech recognition device (18). Location of a desired edit point is greatly facilitated, and editing of the audio recording may be performed by word processing operations on the text alone.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
110 words
A method of editing an audio or audio-visual
recording, the method comprising the steps of: replaying at least part of the recording to generate
an electrical signal representing the audio material
recorded on the recording; applying speech recognition techniques to the
electrical signal to generate a text signal representing
as text spoken words which are included in the audio
material recorded on the recording; displaying at least the text represented by the text
signal generated by the application of speech recognition
techniques to an editing operator; identifying a desired edit by reference to the
displayed text signal; and making an edit such as to edit the audio or
audio-visual recording.
Claim 2
Dependent Claim
31 words
A method according to claim 1, in which the
displaying step includes displaying the text adjacent to a
display of a signal directly representing the waveform of
the said electrical signal.
Claim 3
Dependent Claim
33 words
A method according to claim 1 or 2, in which the
recording is an audio-visual recording and the displaying
step includes the step of displaying the video image
represented by the audio-visual recording.
Claim 4
Dependent Claim
55 words
A method according to claim 1, 2 or 3, in which the
step of making an edit comprises making an edit by
operator commands to cut, copy or paste the text to cause
editing of the text signal and automatically editing the
audio or audio-visual recording in correspondance with the
operations on the text signal.
Claim 5
Dependent Claim
161 words
Apparatus for editing an audio or audio-visual
recording, the apparatus comprising: means (16) for storing an audio or audio-visual
recording; means (14, 16) for replaying at least part of the
recording to generate an electrical signal representing
the audio material recorded on the recording; speech recognition means (18) coupled to the
replaying means to receive the electrical signal and to
apply speech recognition techniques to the electrical
signal to generate a text signal representing as text
spoken words which are included in the audio material
recorded on the recording; a display device (20) coupled to the replaying means
and to the speech recognition means for displaying at
least the text represented by the text signal generated by
the speech recognition means to an editing operator; and editing means (14) for making an edit at a point
identified by an operator by reference to the displayed
text signal such as to edit the audio or audio-visual
recording stored on the storage means.
Claim 6
Dependent Claim
32 words
Apparatus according to claim 5, in which the display
device displays the text signal (36) adjacent to a display
of a signal (34) directly representing the waveform of the
said electrical signal.
Claim 7
Dependent Claim
21 words
Apparatus acccrding to claim 5 or 6, in which the
display device also displays a video image derived from
the recording.
Claim 8
Dependent Claim
54 words
Apparatus according to claim 5, 6 or 7, in which the
editing means (14) includes a text editor responsive to
operator commands to cut, copy or paste the text by
operating on the text signal and the editing means editing
the audio or audio-visual recording in correspondance with
the operations on the text signal.
Claim 9
Dependent Claim
60 words
Apparatus according to claim 8, in which the display
device is operable in a first mode wherein it displays the
text adjacent to a display of a signal directly
representing the waveform of the electrical signal and in
a second mode wherein it displays the text without the
display of a signal directly representing the waveform of
the electrical signal.
