Abstract:

This project demonstrated hardware and software technology to produce a miniature two-way voice translator capable of operating in high noise environments. This effort built upon Integrated Wave Technologys work with a miniaturized one-way translator. This involved adding separate audio channels for second microphones and speakers. Separate channels allow the circuit board to process the input from the interviewers microphone and to play audio directly to the interviewee. The system was designed to be hand held or pocket-mounted for eyes-free, hands-free operation, to consume a fraction of a watt of power, and to work in high background noise with high accuracy. Speaker independence for the Arabic language was also a goal of this research. There was marginal success due to limited amounts of speech for building universal templates in this language. The accuracy and utility of this device has been demonstrated and documented in this report.
