Abstract
Abstract Audio data processing apparatus connectable to a telephone network, the apparatus comprising a device (50) to receive from the network and record an audio signal comprising a sequence of audio segments separated by audio delimiters, characterised by a device (90) for scanning the recorded signal (65) to detect the audio delimiters (80) and generate a data structure in which a set of predefined field identifiers are each linked to a corresponding one of the recorded audio segments.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
101 words
Audio data processing apparatus connectable to a telephone network (20), the apparatus comprising: means (50) to receive from the network and record an audio signal (65) comprising a sequence of audio segments (70) separated by audio delimiters (80); means (90) for scanning the recorded signal (65) to detect the audio delimiters (80) and generate a data structure (150, 160) comprising a set of audio records (160), each such record containing one of the audio segments (70), and an index file comprising a set of predefined field identifiers each having an associated pointer to a corresponding one of the audio records (160).
Claim 2
Dependent Claim
101 words
Audio data processing apparatus connectable to a telephone network (20), the apparatus comprising: means (50) to receive from the network and record an audio signal (65) comprising a sequence of audio segments (70) separated by audio delimiters (80); means (90) for scanning the recorded signal (65) to detect the audio delimiters (80) and generate a data structure (150, 160) comprising a set of audio records (160), each such record containing one of the audio segments (70), and an index file comprising a set of predefined field identifiers each having an associated pointer to a corresponding one of the audio records (160).
Claim 3
Dependent Claim
24 words
Apparatus as claimed in claim 1 comprising means for editing the index file wherein ones of the recorded audio segments can be selectively processed.
Claim 4
Dependent Claim
59 words
Apparatus as claimed in any preceding claim in which the scanning means (90) has a programmable component, the apparatus further comprising a compiler (100) responsive to a formal description of the set of predefined field identifiers to generate program code for controlling the programmable component to generate the data structure in accordance with the set of predefined field identifiers.
Claim 5
Dependent Claim
87 words
Apparatus as claimed in claim 3 wherein the audio signal receiving and recording means has a programmable component and wherein the formal description of the set of predefined field identifiers comprise structural information defining one of more predefined paths through the set of predefined identifiers, the compiler (100) being responsive to the structural information to generate program code for controlling the audio signal receiving and recording means to prompt a caller to supply information in accordance with the predefined paths through the set of predefined field identifiers.
Claim 6
Dependent Claim
18 words
Apparatus as claimed in claim 1 wherein at least some of the audio delimiters (80) are DTMF tones.
Claim 7
Dependent Claim
22 words
Apparatus as claimed in claim 1 wherein the audio delimiters (80) are DTMF tones each of which identify an associated audio segment.
Claim 8
Dependent Claim
17 words
Apparatus as claimed in claim 1 wherein at least some of the audio segments comprise DTMF tones.
Claim 9
Dependent Claim
117 words
Method for operating audio data processing apparatus to collect information from a caller over a telephone network, the method comprising the steps of receiving over the network from the caller and recording an audio signal (65) comprising a sequence of audio segments (70) separated by audio delimiters (80); and subsequently generating a data structure (150, 160) by scanning the recorded signal (65) to detect the audio delimiters (80) and generating the data structure having a set of predefined field identifiers with each linked to a corresponding one of the recorded audio segments (160); and transcribing selected ones of the audio segments, the results of such transcription being used to prioritize subsequent processing of the recorded signal (65).
Claim 10
Dependent Claim
117 words
Method for operating audio data processing apparatus to collect information from a caller over a telephone network, the method comprising the steps of receiving over the network from the caller and recording an audio signal (65) comprising a sequence of audio segments (70) separated by audio delimiters (80); and subsequently generating a data structure (150, 160) by scanning the recorded signal (65) to detect the audio delimiters (80) and generating the data structure having a set of predefined field identifiers with each linked to a corresponding one of the recorded audio segments (160); and transcribing selected ones of the audio segments, the results of such transcription being used to prioritize subsequent processing of the recorded signal (65).
Claim 11
Independent Claim
105 words
A method for operating an audio data processing apparatus to collect information from callers over a telephone network, said method comprising the steps of: receiving, over the telephone network, information from a caller; recording audio signals representative of the information, said audio signals including a sequence of audio segments separated by audio delimiters; scanning the audio signals to detect the audio delimiters; and generating a data structure comprising a set of audio records with each audio record containing one of the audio segments and an index file comprising a set of tags each having an associated pointer to a corresponding one of the audio records.
Claim 12
Independent Claim
105 words
A method for operating an audio data processing apparatus to collect information from callers over a telephone network, said method comprising the steps of: receiving, over the telephone network, information from a caller; recording audio signals representative of the information, said audio signals including a sequence of audio segments separated by audio delimiters; scanning the audio signals to detect the audio delimiters; and generating a data structure comprising a set of audio records with each audio record containing one of the audio segments and an index file comprising a set of tags each having an associated pointer to a corresponding one of the audio records.
Claim 13
Independent Claim
104 words
A method for operating an audio data processing apparatus to collect information from callers over a telephone network, said method comprising the steps of: receiving over the telephone network information from a caller; recording audio signals representative of the information, said audio signals including a sequence of audio segments separated by audio delimiters; scanning the audio signals to detect the audio delimiters; and using the audio delimiters to generate a data structure comprising audio records with each one containing at least one audio segment and an index file containing identifiers with each identifier being linked to a selected audio segment in the audio records.
Claim 14
Independent Claim
104 words
A method for operating an audio data processing apparatus to collect information from callers over a telephone network, said method comprising the steps of: receiving over the telephone network information from a caller; recording audio signals representative of the information, said audio signals including a sequence of audio segments separated by audio delimiters; scanning the audio signals to detect the audio delimiters; and using the audio delimiters to generate a data structure comprising audio records with each one containing at least one audio segment and an index file containing identifiers with each identifier being linked to a selected audio segment in the audio records.
