Portable terminal device

A portable terminal device capable of carrying out a voice communication which couples a first housing to a second housing to be opened and closed through a hinge portion, and constitutes the first housing to be rotatable around a rotating shaft member which is orthogonal to an opening and closing shaft member of the hinge portion with respect to the second housing, comprising:

• first voice output means, provided on a surface of the first housing which is opposed to the second housing in a closing state;
• second voice output means, provided on a surface of the second housing which is opposed to the first housing in the closing state and having a higher output level than the first voice output means;
• position deciding means, for deciding a positional relationship of the first housing with the second housing;
• and
• setting means, for setting an output source for a voice in a voice communication to either the first voice output means or the second voice output means corresponding to a result of the decision obtained by the position deciding means.
