Abstract

The present invention relates to a method for selecting and downloading content from a content provider which is accessible via an IP/DNS/URL address to a mobile device, the content being any text information data, for converting the text information data to at least one audio message and for storing the at least one audio message as at least one audio file on the mobile device, wherein the at least one audio file is playable and discernable as a music file. Said method implemented on a mobile phone enables controlling and playing the audio messages as music files, for instance also in a car environment with a car kit enabling a control and a selection of one or more of said at least one audio files for playing from the mobile phone.

Claims

a) Reading the IP address or the associated DNS-/URL-address from a memory in the mobile device;

b) Connecting to the content provider via the IP address or the associated DNS-/URL-address and downloading the content from said IP address or the associated DNS-/URL-address to the mobile device, the content being information data and the information data including the character text;

c) Recognizing the character text within the information data and determining by a text message determination rule at least one text message from the character text;

d) Determining by a short title determination rule at least one short title which is an information related to the at least one text message and which is used as an at least one file name for the at least one audio file of the at least one text message;

e) Converting the at least one text message by a Text-to-Speech software (TTS) to the respective at least one audio message;

f) Storing the respective at least one audio message as the at least one audio file on the mobile device with the respective short title as the file name; and

g) Enabling a selection of one or more of said at least one audio files for playing.

2. ) Method according to claim 1, wherein in step a) the memory is an address table, a bookmark table, a register, a database or a data file wherein at least one IP address or associated DNS-/URL-address is stored, wherein the IP address or the associated DNS-/URL-address is preferably input from keys of the mobile device, and/or

wherein in step b) the connection to the IP address or the associated DNS-/URL-address is established wired or wireless and/or

wherein the IP address or the associated DNS-/URL-address is related to a content server associated to the content provider providing email content, the content server being preferably a POP/IMAP, a Microsoft Exchange email server, a Send-mail email server.

3. ) Method according to claim 1, wherein the memory contains a plurality of IP addresses or associated DNS-/URL-addresses and wherein the steps a)-f) are executed recursively for each IP address or associated DNS-/URL-address contained in the memory.

4. ) Method according to claim 1, wherein prior to step a) a control function is executed, the control function detecting the selection by an user and the playing of a control audio file, whereupon the control function initiates, based on a unique file name of the control audio file, an execution of the steps a)-g) with a certain IP address or associated DNS-/URL-address which is retrieved from the memory based on the unique file name of the control audio file, and wherein the detection of the selection and playing of the control audio file is done by polling.

5. ) Method according to claim 1, wherein in step f) the audio file gets stored in already available or foreseen either folder, directory or database structures like a music file.

6. ) Method according to claim 1, wherein the mobile device is a smart-phone, a mobile phone, a music player, a laptop, a PC, wherein the mobile device comprises means for a wired and/or a wireless data connection.

7. ) Method according to claim 1, wherein in step d), in addition to the determination of the short title, at least one headline is determined by a headline determination rule and set in front of the at least one text message, in order to inform the listener at the beginning of the playing of the audio message preferably about the source, the date of the message, a content of the text message and a keyword, the headline determination rule taking into account one or more of:

the respective IP address or the respective associated DNS-/URL-address as a source;

a character string of a database table assigned to the IP address or to the associated DNS-/URL-address;

the character text;

the text message;

the first sentence of the text message;

attributes of words within the at least one text message as e.g. bold words, big or underlined words, the date connected to the respective at least one text message and the keyword.

8. ) Method according to claim 1, wherein in step d) the short title determination rule takes into account an information source based on the IP address or the associated DNS-/URL-address, an email sender, a name from a connected database table associated with the IP address or to the associated DNS-/URL-address, the content or the date of the text message, a keyword, a content of the respective headline or parts thereof, in order to build a descriptive audio file name understandable for a respective selection for a playing, the descriptive audio file name having a length suitable for displaying on the mobile device;

and/or

wherein the short title determination rule takes into account already existing audio files based on a root name and an incremented number related to the already stored audio files of a same kind.

9. ) Method according to claim 1, wherein in step c) at least two text messages are determined by the text message determination rule, wherein the text message determination rule is based on a recognition of different paragraphs by detection of one or more of:

line spacing, bold, underlined words, big sized words, keywords, and whereupon each of the determined at least two text messages are extracted as a separate text message, in order to generate by the steps following step c) from each separate text message the at least one audio message and audio file, respectively, and/or

wherein the text message determination rule takes into account old text messages from a same IP address or associated DNS-/URL-address, detecting which information is new, taking the new information as the text message, and rejecting the text messages which are already part of already existing converted audio files.

10. ) Method according to claim 1, wherein in step a) at least one IP address or associated DNS-/URL-address is an email address, an instant messaging or a social network address, and wherein in step b) at least one email with or without data attachment, an instant message or a social network feed message gets downloaded, and/or

wherein one or more of the source or the sender, the reference line, the date of reception is taken into account for the determination of the short title and within the headline determination rule.
