Operating Basics
Using the microphone
You can use the built-in or an external microphone that connects to the
microphone jack 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 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 the TOSHIBA Face Recognition
TOSHIBA Face Recognition uses a face verification library to verify the
face data of users when they log in to Windows. The user can thus avoid
having to enter a password or the like, which makes the login process
easier. This software is preinstalled with some models.
Note on Use
■ TOSHIBA Face Recognition does not guarantee the correct
identification of a user. Changes to the likeness of a registrant, such as
hair style changes, wearing a cap, or wearing glasses may effect the
recognition rates when such changes occur after the registrant had
registered.
■ TOSHIBA Face Recognition may incorrectly recognize faces that are
similar to a registrant.
■ For high security purposes, TOSHIBA Face Recognition is not a
suitable substitute for Windows passwords. When security is a high
priority, use your established Windows passwords to log in.
