Operating Basics
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)
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.
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 pre-
installed with some models.

TOSHIBA Face Recognition does not guarantee the correct identification of
a user. Changes to the likeness of a registrant, such as hair style changes,
