MiPad is one of the application prototypes in a project codenamed
Dr Who. As a wireless Personal Digital Assistant (PDA), MiPad
fully integrates continuous speech recognition (CSR) and spoken
language understanding (SLU) to enable users to accomplish
many common tasks using a multimodal interface and wireless
technologies. It tries to solve the problem of pecking with tiny
styluses or typing on minuscule keyboards in today’s PDAs or
smart phones. It also avoids the problem of being a cellular
telephone that depends on speech-only interaction. MiPad
incorporates a built-in microphone that activates whenever a field
is selected. As a user taps the screen or uses a built-in roller to
navigate, the tapping action narrows the number of possible
instructions for spoken language processing. MiPad currently runs
on a Windows CE Pocket PC with a Windows 2000 Server where
speech recognition is performed. The Dr Who CSR engine has a
64k word vocabulary with a unified context-free grammar and ngram
language model. The Dr Who SLU engine is based on a
robust chart parser and a plan-based dialog manager. This paper
discusses MiPad’s design, implementation work in progress, and
preliminary user study in comparison to the existing pen-based
PDA interface.
