The first release of the open sapi tool for rbutil has been confirmed to work under Windows and Linux but Mac testting is still needed. This tools allows the generation of supporting speech files needed for the speech accessibility features found in rockbox. This allows the user to take a standard SAPI voice and use it on Windows, Mac and Linux systems to produce text to speech clips in wav format.
The code rework from the main project has allowed for more efficient and faster code execution. The analysis of time critical function has enabled me to use tihe most time efficient commands in these areas.
Now using the system under Ubuntu Linux in combination with speech dispatcher, pulseaudio and Orca we recieive performance close to that currently seen with espeak.
Making the server multi threaded has increases the scailability of the system. There are still increased time improvements to be made with the full intergration into speech dispatcher with a native open sapi module.
Further development of the threading model will enable the server to handel multiple client efficiently.
This has help ease the worry of the looming question of will the system ever been effecient enough to do real time speech synthesis. There are still problems to iron out but we are well on the way.
