The speech recognition system is a completely assembled
and easy to use programmable speech recognition circuit.
Programmable, in the sense that you train the words (or vocal
utterances) you want the circuit to recognize. This board allows
you to experiment with many facets of speech recognition
technology. It has 8 bit data out which can be interfaced with
any Microcontroller for further development. Some of
interfacing applications which can be made are controlling home appliances, robotics movements, Speech Assisted
technologies, Speech to text translation, and many more. The
schematic diagram of voice recognition kit is shown in Fig 5.
The circuit is built with the features of self-contained
standalone speech recognition, reprogrammable, up to 20 word
vocabulary of duration two second each, multi-lingual, nonvolatile
memory back up with 3V battery onboard which
maintains the speech recognition data in memory even after
power off. Also the kit can be easily interfaced to control
external circuits and appliances.
