| Speakup is a kernel based screen review package for the linux operating |
| system. It allows blind users to interact with applications on the |
| linux console by means of synthetic speech. |
| |
| Currently, speakup has several issues we know of. |
| |
| The first issue has to do with the way speakup communicates with serial |
| ports. Currently, we communicate directly with the hardware |
| ports. This however conflicts with the standard serial port drivers, |
| which poses various problems. This is also not working for modern hardware |
| such as PCI-based serial ports. Also, there is not a way we can |
| communicate with USB devices. The current serial port handling code is |
| in serialio.c in this directory. |
| |
| Some places are currently using in_atomic() because speakup functions |
| are called in various contexts, and a couple of things can't happen |
| in these cases. Pushing work to some worker thread would probably help, |
| as was already done for the serial port driving part. |
| |
| There is a duplication of the selection functions in selections.c. These |
| functions should get exported from drivers/char/selection.c (clear_selection |
| notably) and used from there instead. |
| |
| The kobjects may have to move to a more proper place in /sys. The |
| discussion on lkml resulted to putting speech synthesizers in the |
| "speech" class, and the speakup screen reader itself into |
| /sys/class/vtconsole/vtcon0/speakup, the nasty path being handled by |
| userland tools. |
| |
| Another issue seems to only happen on SMP systems. It seems |
| that text in the output buffer gets garbled because a lock is not set. |
| This bug happens regularly, but no one has been able to find a situation |
| which produces it consistently. |
| |
| Patches, suggestions, corrections, etc, are definitely welcome. |
