Description

METHOD AND APPARATUS FOR INTERACTIVE AUDIO TECHNICAL FIELD
[0001] The invention relates generally to the field of audio advertisement, and in particular to a method and apparatus enabling interactive response to an audio advertisement. BACKGROUND OF THE INVENTION
[0002] Various forms of media are supported to a great extent by advertising income. Newspapers, magazines, television, radio and many Internet based information providers are to a great extent funded by income derived from advertising. Internet advertising has garnered a large share of advertising dollars, primarily due to its interactive features. In particular, an individual viewing a web page may click on a link, bringing the individual to a potential sales site. Thus, a clicking individual is an interested potential lead, and payment to lead source can be reliably apportioned.
[0003] The above feature is however basically absent from most other forms of advertising. In particular, newspapers, magazines, television and radio advertisements lack the interactivity of the Internet, and it is thus much more difficult to track the impact of a particular advertisement. Furthermore, an interested potential lead must take significantly more action than simply clicking a mouse in order to indicate interest in a particular advertised product.
[0004] The above difficulty has led to the use of dedicated toll free numbers, and coupons which may be clipped and used for discounts at points of purchase. Certain inroads have been made with television advertising driving in the direction of interactivity by allowing a viewer to respond to an advertisement by clicking on an icon displayed on the screen.
[0005] Unfortunately, the above does not resolve the issue for audio advertisements, and particularly radio advertisements. Many radio listeners, i.e. potential consumers, listen while in motion, either as pedestrians or in moving vehicles. Thus any requirement to click on a particular icon, or to call a particular number, will not lead to satisfactory results. [0006] Arbitron Inc., of Columbia, Maryland provides a Portable People
Meter™ (PPM™) which is operative to track what consumers listen to on the radio, and what consumers watch on broadcast TV, cable and satellite TV. The PPM works by detecting identification codes that are embedded into the audio portion of a transmission which is to be tracked. Such a technology enables an advertiser to get statistical information on listeners based on the information tracked by the PPM, however this technology does not provide the needed interactivity. Furthermore, it requires the advertiser to embed an identification code, which adds expense.
[0007] There is thus a long felt need for a method and apparatus to provide interactivity for audio advertising.
SUMMARY OF THE INVENTION
[0008] In view of the discussion provided above and other considerations, the present disclosure provides methods and apparatus to overcome some or all of the disadvantages of prior and present methods of audio advertising feedback. This is accomplished in certain embodiments by providing an audio recorder exposed to the audio output of an audio advertisement receiver, such as a radio or TV. The audio recorder is arranged to maintain a trailing audio record of the audio output by the audio advertisement receiver. A user input device is further provided.
[0009] A user expressing an interest in an audio advertisement provides a user input. The user input may be in the form of a switch or voice recognition without limitation. Responsive to the user input, a function of the trailing audio record is transmitted, optionally being a compressed predetermined portion of the trailing audio record, to a server, along with identification information associated with the source of the user input. Preferably, the identification information comprises a device identifier associated with the audio recorder or identification information associated with the transmitter of the audio record. Optionally a date and time stamp, and further optionally audio channel information, is further transmitted. In one non-limiting embodiment, the audio record and associated information is transmitted over a registered user cellular telephone utilizing general packet radio service (GPRS) or other cellular services.
[00010] The server, responsive to the received audio record, is operative to identify the audio record and correlate the audio record with an advertisement. In one embodiment, the server compares particular acoustical properties of the received audio record with a database of advertisements.

In another further embodiment the server further comprises a lead forwarding module arranged to forward user associated information to a predetermined source of the identified maintained trailing portion of audio.
[00019] Independently, certain embodiments provide for a method of providing interactive response to an audio message part, the method comprising: maintaining a trailing portion of the audio message part; receiving a user input; and transmitting a function of the maintained trailing portion of the audio message part responsive to the received user input.
[00020] In one further embodiment, the received user input is a voice command. In another further embodiment the transmitting is via a cellular network.
[00021] In one further embodiment the method further comprises, prior to the transmitting, compressing the maintained trailing portion of the audio message part, wherein the transmitted function of the maintained trailing portion of the audio message part is the compressed maintained trailing portion of the audio message part. In another further embodiment the transmitted function of the maintained trailing portion of the audio message part is the maintained trailing portion of the audio message part.
[00022] In one further embodiment the method further comprises transmitting identification information with the transmitted function of the maintained trailing portion of the audio message part. In another further embodiment the maintained trailing portion is of a predetermined time length.
[00023] In one further embodiment the method further comprises: receiving the transmitted function of the maintained trailing portion of the audio message part; and identifying the transmitted maintained trailing portion of the audio message part.

[00034] In operation, audio capture device 20 is exposed to the audio output of an audio advertisement receiver, such as a radio. Microphone 30 receives the audio output and, in one embodiment, via A/D converter 35, stores a digital conversion of the audio output on memory 40, and particularly on trailing audio section 44. In another embodiment, in which identification information of an advertisement is encoded on the received radio wave at a human inaudible frequency, the received radio output is filtered through a filter (not shown) and only the necessary information is converted by A/D converter 35 and stored on memory 40. Memory 40 stores the digitized audio output for a predetermined amount of time, thus maintaining a trailing audio portion of the audio output by the audio advertisement receiver. Additionally, memory 40 optionally stores a date and time stamp and audio channel information.
[00035] The above has been described in an embodiment in which audio capture device is exposed to the audio output of a receiver, such as a radio or television, however this is not meant to be limiting in any way. In another embodiment A/D converter 35 is in communication with the audio device, and receives the audio signal in either analog or digitized format without requiring microphone 30. [00036] A user expressing an interest in an audio advertisement provides a user input via user controlled input device 50. In the embodiment in which user controlled input device 50 is a voice recognition device, the user speaks a predetermined word or set of words, and control circuitry 70 is operative to identify the selected command works received via microphone 30 and digitized via A/D converter 35. In the embodiments in which user controlled input device 50 is a mechanical switch or a touch screen, the user toggles the switch or touches a predetermined spot on the touch screen. Responsive to the user input at user controlled input device 50, control circuitry 70 extracts from trailing audio section 44 of memory 40 the stored trailing audio portion, optionally compresses the extracted trailing audio via compression functionality 75, and transmits the optionally compressed trailing audio to server 80 via communication module 60. Optionally, control circuitry 70 further extracts any relevant identification information from ID section 42 and transmits the extracted identification information along with the optionally compressed trailing audio to server 80 via communication module 60. In one non-limiting embodiment, communication module 60 is a Bluetooth link and the trailing, optionally compressed, audio portion and optional identification information is transmitted over user cellular telephone 62 utilizing general packet radio service (GPRS) or other cellular service via cellular network 67. Optionally, identification information associated with cellular telephone 62 is further transmitted by cellular network 67 along with the transmitted, optionally compressed, audio portion.
[00037] In one embodiment control circuitry 70 is further arranged to retrieve from user cellular telephone 62 an identifier associated with user cellular telephone 62, such as the SIM card identification number, and the telephone number of user celluar telephone 62, such as the MSISDN of user cellular telephone 62, and store the retrieved information in ID section 42. The retrieved information from user cellular telephone 62 is preferably transmitted as relevant identification information association with identification informaiton of audio capture device 20.
[00038] In another embodiment, ID section 42 is pre-programmed with identification information, and in a registration phase a user associate the preprogrammed identification information of the ID section 42 with user identification information, such as an MSISDN of user telephone 62. Thus, upon transmission of the pre-programmed information from ID section 42, user identification and a contact call back number is thus provided. [00039] In yet another embodiment, particularly applicable in the event communication module 60 is arranged to be in Bluetooth communication with user cellular telephone 62, communication module 60 controls user cellular telephone 62 to call server 80 at a predetermined phone number with instructions to provide caller ID. In one embodiment this is accomplished by controlled user cellular telephone 62 to make the call with a non-masked number code, such as *31#. In the event that server 80 does not have a record of user cellular telephone 62, server 80 will answer the call, and in one particular embodiment communication module 60 will transfer identification information from ID section 42, either digitally or as DTMF encoded signals, thus associating user cellular telephone 62 with pre-programmed identifying information for audio capture device 20. Alternately, control circuitry 70, upon detection that user cellular telephone 62 has provided new identification information not previously stored in ID section 42, forces server 80 to answer by maintaining the calling signal longer than a predetermined minimum number of call signal, i.e. more than a predetermined number of rings. Server 80 is then arranged to respond and thus receive the registration information identification information thereby associating user cellular telephone 62 with pre-programmed identifying information for audio capture device 20.
[00040] The transmitted trailing audio portion and identification information is received by receiver 90. Audio identification module 100 is operative to identify the received trailing, optionally compressed, audio portion and locate a correlating product or service in database 110. Preferably, in the event that the received trailing portion has been compressed, audio identification module is operative to decompress the received trailing audio portion via optional decompression functionality 105. In one embodiment audio identification module 100 compares particular acoustical properties of the received trailing audio portion, also known as a digital fingerprint, with the stored digital fingerprints of advertisements in database 110. In another embodiment the inaudible encoded message is emphasized and associated with stored inaudible encoded messages in database 100 thus providing advertisement identification. In one embodiment, responsive to the successful identification of a product or service, a notification, including the received user and/or device and/or cellular telephone identification information and information about the identified product or service, is sent to the respective advertiser notifying the advertiser that a user is interested in the identified product or service via lead forwarding functionality 120. Advantageously, the advertiser can now directly contact the user interested in their product or service. Further advantageously, advertisers can accumulate statistical data of the success of their advertisements.
[00041] The above has been described in an embodiment in which the trailing audio portion, optionally compressed, is transmitted to the server for identification, however this is not meant to be limiting in any way. In another embodiment, some or all, of the functionality of server 80 is provided within audio capture device 20. In one particular embodiment, audio identification module 100 and database 110 are provided within audio capture device 20, and thus only advertisement identification and user identification information is transmitted by communication module 60. Advantageously, complementary information can be displayed on an optionally supplied screen, such a discount coupon. In another embodiment, complementary information is transmitted to user cellular telephone 62.
[00042] In one embodiment server 80 is further arranged to transmit an audio file to audio capture device 20, to be output at predetermined times, such as at start up of the audio capture device 20. In one particular embodiment such an audio file may constitute an advertisement.
[00043] Fig. 2 illustrates a high level flow chart of an embodiment of a method of providing interactive response to an audio message. In stage 1000, a trailing portion of a target audio, such as an advertisement of a product or service, is maintained on an audio capture device. As described above in relation to Fig. 1, in one embodiment this is accomplished by exposing a microphone to the target audio of stage 1000, such as a radio, and storing a trailing digitized representation of the target audio on a memory, optionally the trailing representation is of a predetermined amount of time. In stage 1010 a user input is received indicating an expressed interest of a user. In one embodiment the user input is an activation of voice activated switch. In another embodiment the user input is a toggled mechanical switch. In yet another embodiment the user input is a touched spot on a touch screen.
