Using The Microphone - Toshiba PSU40C-DW208C User Manual

Using the microphone

Your computer has a built-in microphone that can be used to record
monaural sounds into your applications. It can also be used to issue voice
commands to applications that support such functions. (Built-in microphone
is provided with some models)
Since your computer has a built-in microphone and speaker, "feedback"
may be heard under certain conditions. Feedback occurs when sound from
the speaker is picked up in the microphone and amplified back to the
speaker, which amplifies it again to the microphone.
This feedback occurs repeatedly and causes a very loud, high-pitched
noise. It is a common phenomenon that occurs in any sound system when
the microphone input is output to the speaker (throughput) and the speaker
volume is too loud or too close to the microphone. You can control
throughput by adjusting the volume of your speaker or through the Mute
function in the Master Volume panel. Refer to your Windows documentation
for details on using the Master Volume panel.
Using TOSHIBA Face Recognition
If your computer is equipped with a web camera, the TOSHIBA Face
Recognition feature can be used to verify the face of users when they log
on to Windows. If the verification is successful, a user will be logged on to
Windows automatically. The user can thus avoid having to enter a
password, which makes the login process easier.
Notes
Please note the following hints when using TOSHIBA Face Recognition:
■
Changes of the likeness of a registrant such as hair style changes,
wearing of a cap or wearing glasses may prevent a registrant from
being recognized correctly. In this case, log on to Windows using your
password.
■
Bright background light and/or shadows may prevent a registrant from
being recognized correctly. In this case, log on to Windows using your
password.
■
Faces similar to a registrant's may be recognized accidently.
Warning: Do not use TOSHIBA Face Recognition for high-security
purposes. It is not a suitable substitute for Windows password security. Use
your established Windows passwords for security-sensitive log on.
Disclaimers
Toshiba does not guarantee that the face recognition utility technology will
be completely secure or error-free. Toshiba does not guarantee that the
face recognition utility will accurately screen out unauthorized users at all
times. Toshiba is not liable for any failure or damage that might arise out of
the use of the face recognition software or utility.
