Speech Input

Speech Input

1. How it works

   • The data is inputted in audio form, either directly, via a microphone, or indirectly, via an audio tape .
   • Software analyses the inputted sound and matches it against library of sounds
   • When a match is found the value is sent for processing

2. Applications

   • allows users to dictate text straight into the computer
   • It has also been used in control systems, e.g. instructions to robots in the manufacturing industry

3. Strengths

   • A user can speak much more quickly than even the most skilled of typists can type

4. Limitations

   • Interpreting human language is a complex process
   • The human voice is not uniform: we speak in different styles and different accents
