TEXT TO SPEECH

DESCRIPTION

PRODUCT NAME: TEXT TO SPEECH

PRODUCT DESCRIPTION:

     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.

FEATURES

Ø  Self-contained stand alone speech recognition circuit

Ø  User programmable

Ø  Up to 20 word vocabulary of duration two second each

Ø  Multi-lingual

Ø  Non-volatile memory back up with 3V battery onboard. Will keep the speech recognition data in memory even after power off.

Ø  Easily interfaced to control external circuits & appliances

Applications

There are several areas for application of voice recognition technology.

  • Speech controlled appliances and toys
  • Speech assisted computer games
  • Speech assisted virtual reality
  • Telephone assistance systems
