How It Works

Using the Dr. Who engine on a mobile device, end users can essentially talk to their devices and have the device understand the intended meaning of their commands and execute the requested tasks. Because mobile devices are often too underpowered to perform continuousspeech recognition by themselves, techniques such as distributedspeech recognition can be applied to stream the audio signal back to a server computer. The server computer performs the processing and interpretation of the spoken command, then sends the resulting action to be taken back to the mobile device for execution.

This type of technique can be applied for general dictation and more advanced functionality such as meeting scheduling. Tasks such as scheduling can be made more accurate by combining modalities. For example, a user can verbally request a meeting while simultaneously tapping certain areas of their calendar onscreen to provide more guidance to the computer.
