Editing Screen reader (section)

=== Web-based ===

A relatively new development in the field is web-based applications like Spoken-Web that act as web portals, managing content like news updates, weather, science and business articles for visually-impaired or blind computer users.{{citation needed|date=January 2015}} Other examples are ReadSpeaker or [[BrowseAloud]] that add [[text-to-speech]] functionality to web content.{{citation needed|date=January 2015}} The primary audience for such applications is those who have difficulty reading because of learning disabilities or language barriers.{{citation needed|date=January 2015}} Although functionality remains limited compared to equivalent desktop applications, the major benefit is to increase the accessibility of said websites when viewed on public machines where users do not have permission to install custom software, giving people greater "freedom to roam".{{citation needed|date=January 2015}}

This functionality depends on the quality of the software but also on a logical structure of the text. Use of headings, punctuation, presence of alternate attributes for images, etc. is crucial for a good vocalization. Also a web site may have a nice look because of the use of appropriate two dimensional positioning with CSS but its standard linearization, for example, by suppressing any CSS and Javascript in the browser may not be comprehensible.{{citation needed|date=January 2015}}
