## Abstract

Embodiments may be a standalone module or part of mobile devices, desktop computers, servers, stereo systems, or any other systems that might benefit from condensed audio presentations of item structures such as lists or tables. Embodiments may comprise logic such as hardware and/or code to adjust the temporal characteristics of items comprising words. The items maybe included in a structure such as a text listing or table, an audio listing or table, or a combination thereof, or may be individual words or phrases. For instance, embodiments may comprise a keyword extractor to extract keywords from the items and an abbreviations generator to generate abbreviations based upon the keywords. Further embodiments may comprise a text-to-speech generator to generate audible items based upon the abbreviations to render to a user while traversing the item structure.

### Claim 8

An apparatus for adjustment of temporal acoustical characteristics of words in an item structure, the apparatus comprising:
a keyword extractor to receive the item structure comprising at least a first item, the first item to represent a first set of one or more words, the keyword extractor to extract one or more keywords from the first set to generate a first keyword item, the keyword extractor to select the one or more keywords to distinguish the keyword item from other items; and
an abbreviations generator to abbreviate the keyword item by generating a first alternative representation for the first keyword item to create a first abbreviated item, the abbreviations generator to store the first abbreviated item.

### Claim 9 (depends on 8)

The apparatus of claim 8, further comprising a text mining knowledge base coupled with the keyword extractor to store data related to word comprehension and grammar, wherein the keyword extractor comprises logic to extract the one or more keywords based upon the data related to word comprehension and grammar.

### Claim 10 (depends on 8)

The apparatus of claim 8, further comprising a user context and history module coupled with the keyword extractor to store data related to user context and history, wherein the keyword extractor comprises logic to extract the keywords based upon the data related to user context and history.

### Claim 11 (depends on 8)

The apparatus of claim 8, further comprising an audio knowledge base coupled with the abbreviations generator to store data related to pronunciation of the one or more keywords, wherein the abbreviations generator generates altered representations of the one or more keywords based upon the data related to pronunciation of the one or more keywords.

### Claim 12 (depends on 8)

The apparatus of claim 8, further comprising a text-to-speech generator to generate an audible item for the first abbreviated item by creating an audio rendering of the first abbreviated item in a data storage format.

### Claim 13 (depends on 8)

The apparatus of claim 8, further comprising an audible user interface controller, an indication of a number of speeds, the number of speeds to represent different speeds with which the audible user interface controller may sound the first abbreviated item.

### Claim 14 (depends on 13)

The apparatus of claim 13, wherein the abbreviations generator comprises logic to receive an indication of a number of speeds, the number of speeds to represent different speeds with which the audible user interface controller may sound the first abbreviated item, and to generate more than one first alternative representations, to create more than one first abbreviated items corresponding to the first keyword item, each of the more than one first abbreviated items to represent a different speed of the number of speeds.

### Claim 15

A system for adjustment of temporal acoustical characteristics of words in an item structure, the system comprising:
an audible item structure generator to receive the item structure comprising at least a first item, the first item to represent a first set of one or more words, the audible item structure generator comprising:
