The CVoiceControl Handbook: Introduction

## 1. Introduction

CVoiceControl is a tool that gives the user voice control over unix commands. A template matching based speaker dependent isolated word recognition approach is employed.

Note, that isolated word does not necessarily mean one single word. It just describes a class of recognition systems among

- Isolated word
- Connected words
- Continuous speech
- Spontaneous speech

Consider the following example:

CVoiceControl knows five utterances (being connected to appropriate commands ...)

- connect to internet
- netscape communicator
- one xterm please
- launch emacs NOT VI!
- how are you today?

In this example the recognition vocabulary consists of five ``words'' (=utterances) that can only be recognized one at a time, i.e you cannot connect the words to build ``sentences'' like ``how are you today? please launch netscape communicator and connect to internet''!

Important Note:

As mentioned above you do not need to use one single word as an utterance - and it is strongly recommended to use longer sequences !!!!! This is due to the underlying concept of this recognition system: template matching. Thus, if you use short commands like say xterm and xedit confusability will increase significantly and therefore recognition accuracy will drop rapidly!!!
