1. A device for automatic speech recognition (ASR) comprising:
- a multi-mode voice controlled user interface employing at least one hardware implemented computer processor, wherein the user interface is adapted to conduct a speech dialog with one or more possible speakers and includes;
a broad listening mode which accepts speech inputs from the possible speakers without spatial filtering; and
a selective listening mode which limits speech inputs to a specific speaker using spatial filtering;
wherein the user interface switches listening modes in response to one or more switching cues.
