The picture shows an improved version of the current device used by Largerís team to recognize spoken digits from 0 to 9. Due to the bulky electronics, it takes the current version of the device around 20 milliseconds to recognize each digit. However, by using state-of-the-art integrated optoelectronic technologies, already standard in the telecommunications industry, it will be possible to recognize a digit in a fraction of a microsecond.
