Speech is conveyed through a succession of pronounced phonemes. The duration of these sounds can be altered without altering their tone quality or pitch. The basic patents are expired. New and improved software can be protected by copyrights.
The future of training, apprenticeship, institutional education, home schooling, and independent learning can be drastically changed through improvements in media presentation brought about by programmers using ordinary computers.
Consider this future high school study hall: Each desk has a video monitor, keyboard, pointing device, and headphones. Input from the keyboard and pointing device select the speed of presentation (from very slow to very fast). The video needs to track the audio. Selections must include going back a word, a sentence, a paragraph, a page, or whatever. The video needs to include visual mnemonics associated with the audio. The spelling of new words can also be displayed.
The speech produced by some people is more intelligible than that produced by other people. Recorded speech can be enhanced by making phonemes more consistent and more distinct from each other than they are likely to be naturally. Existing software does not provide smooth transitions between phonemes and clarity suffers when compression exceeds a factor of 1.8. These enhancements represent a valuable service. Flash drives could fill libraries and store shelves.
There are many aspects to this business. Any organization that needs to train people will value the fact that people hear faster than they can read.
