1. A method for use with a multimodal computing device capable of displaying visual messages comprising the steps of:
- providing a multimodal interface that includes an audio interface and a visual interface;
sampling for a background noise to produce a sampled noise level;
comparing the sampled noise level with a first predetermined noise threshold;
in response to determining that the sampled noise level is above the first predetermined noise threshold, enabling interaction with the user via the visual interface by providing at least one visual prompt for user input;
comparing the sampled noise level with a second predetermined noise threshold; and
in response to determining that the sampled noise level is below the second predetermined noise threshold;
disabling interaction with the user via the audio interface;
enabling interaction with the user via the visual interface;
determining whether earphones are connected to the multimodal computing device; and
when it is determined that earphones are connected to the multimodal computing device, re-enabling interaction with the user via the audio interface.

Abstract
A method for enhancing voice interactions within a portable multimodal computing device using visual messages. A multimodal interface can be provided that includes an audio interface and a visual interface. A speech input can then be received and a voice recognition task can be performed upon at least a portion of the speech input. At least one message within the multimodal interface can be visually presented, wherein the message is a prompt for the speech input and/or a confirmation of the speech input.
