1. A portable terminal, comprising:
- a wireless network interface configured to receive, from a server, a set of instructions comprising at least one location, a set of actions to be carried out by a user at the at least one location, and a set of audio processing parameters associated with the at least one location;
a speech synthesizer configured to synthesize a speech command to proceed to the at least one location;
an audio circuit configured to receive audio signals picked up by a microphone and processes the audio signals;
a speech recognition module configured to receive processed signals from the audio circuit and carry out a speech recognition process thereupon to confirm arrival of the user at the at least one location; and
a processor configured to, in response to the speech recognition module carrying out the speech recognition process to confirm the arrival of the user at the at least one location, load the set of audio processing parameters associated with the at least one location, so that speech signals received from the microphone are processed using the set of audio processing parameters associated with the at least one location.

Abstract
A portable terminal has a network interface that receives a set of instructions having a sequence of at least one location and audio properties associated with the at least one location from a server. An audio circuit receives audio signals picked up by a microphone and processes the audio signals in a manner defined by the audio properties associated with the at least one location. A speech recognition module receives processed signals from the audio circuit and carries out a speech recognition process thereupon.

4. A method of processing speech signals at a portable terminal, comprising:
-
receiving a set of instructions from a server, the set of instructions comprising at least one location, a set of actions to be carried out at the at least one location, and a set of audio processing parameters associated with the at least one location; synthesizing a speech command to proceed to the at least one location; receiving a speech signal from a microphone confirming arrival at the at least one location; loading the audio processing parameters associated with the at least one location; and processing speech signals received from the microphone using the audio processing parameters associated with the at least one location. - View Dependent Claims (5, 6, 7, 8, 9, 10)

11. A method of processing speech signals at a portable terminal, comprising:
-
receiving a set of instructions from a server, the set of instructions comprising at least one location, a set of actions to be carried out at the at least one location, and a set of audio processing parameters associated with the at least one location; synthesizing a speech command to proceed to the at least one location; receiving a speech signal from a microphone confirming arrival at the at least one location; loading, in response to the receiving of the speech signal from the microphone confirming arrival at the at least one location, the audio processing parameters associated with the at least one location; and then processing speech signals received from the microphone using the audio processing parameters associated with the at least one location. - View Dependent Claims (12, 13, 14, 15, 16, 17)
