7. The computer-readable memory according to claim 6 , further comprising: converting the symbolics into text using symbolic metadata.
6. A computer-readable memory having stored therein one or more sequences of instructions which when executed by a computer system causes the computer system to implement a server based screen reading method, comprising: receiving display information from an application operating on said server; parsing said display information such that symbolics and text content of the display information are detected by said server; extracting said text and symbolics from the display information by said server; converting the text and symbolics into a first performant format comprising a representation of phonemes in the text and symbolics, the first performant format being selected based on a first bit rate of transmission across a network to a first client machine; converting the text and symbolics into a second performant format comprising a representation of diphones in the text and symbolics, the second performant format being selected based on a second bit rate of transmission across the network to a second client machine; transmitting the text and symbolics in the first performant format from said server onto said network to the first client machine, the first client machine being configured to convert the text and symbolics in the first performant format to a first device specific format for rendering on the first client machine; and transmitting the text and symbolics in the second performant format from said server onto said network to the second client machine, the second client machine being configured to convert the text and symbolics in the second performant format to a second device specific format for rendering on the second client machine, wherein the first device specific format is different from the second device specific format, wherein the text and symbolics in the first performant format requires less memory and transmission capacity comparing to the text and symbolics in the second performant format.
