|Where does NaturallySpeaking performance come from?
||In order to get the most accurate recognition, NaturallySpeaking
In order to obtain the best "performance", one must reduce or eliminate
any factors that will slow any of these 4 processes.
- Hear clearly what was said.
- Match the acoustical information with words in the vocabulary
- Adjust the word selection based on the statistical word association
and frequency of usage model developed in the current voice profile.
- Write the identified words or execute the identified command.
NaturallySpeaking tries to be as accurate as possible, taking as much time
as possible to achieve the best results. Increasing performance is
accomplished by reducing the time it takes NaturallySpeaking to arrive at
an acceptable "recognition solution". Assuming that everything that
can be done concerning #1 (signal clarity) has been done, we are left with
increasing Disk Access performance and reducing CPU processing overhead
to maximize NaturallySpeaking performance.
- Signal clarity depends primarily on microphone quality, sound
card recording quality, position of microphone, and dictation style
- Acoustical matching is a very CPU intensive process with
a great deal of disk access involved to look up vocabulary information.
- Statistical analysis is also a very CPU intensive process and
may also require disk access.
- Writing to the screen is a CPU process and also depends to
some degree on video card performance.
|What can be done to increase Performance?
Increasing Disk Access Performance
- Maintain good "Hard Disk Hygiene" - check the disk for errors
and defragment the files routinely. This could be once a week for
someone who creates and deletes a large number of files or once a month
for less intense computer operation.
- Do not try to use NaturallySpeaking from Network Drives or
compressed drives as the access time for these types of drives is usually
- Do not over fill a drive. A drive should not be more
than 85% full. If less than 15% of the drive NaturallySpeaking is
using (usually C:) is free, try deleting some files, empty the Recycle Bin
and defragment the drive.
Reducing CPU Overhead
- In some cases it may be very helpful to turn off as much of
the Windows Office automatic features as possible. Turn off the office
assistant, auto correct, and animations. Even try turning off auto
spell check and auto grammar check. Check the Office Help in each application
(Word, Excel, etc.) for the steps to accomplish this as the settings are
in different places depending on the version of Microsoft Office.
- In Windows XP, turn off all the performance drainers by optimizing
XP for maximum performance. In My Computer, Properties, Advanced ,
Performance Settings, select "Adjust for best performance".
- In NaturallySpeaking 7 Professional, use the Acoustic Optimizer
in the Tools, Accuracy Center. Running the Acoustic Optimizer periodically
helps NaturallySpeaking to identify words faster, producing better performance.
- If possible, run fewer programs at one time.
- Increase the RAM in the computer. This reduces the amount
of "swapping" that is required by the CPU in order to keep necessary information
in the main system memory.
- Make sure that your computer meets or exceeds the minimum recommended system, not the minimum system
