This paper studies the effect of Bluetooth wireless channels on distributed speech recognition. An approach for implementing speech recognition over Bluetooth is described. We simulate a Bluetooth environment and then incorporate its performance, in the form of packet loss ratio, into the speech recognition system. We show how intelligent framing of speech feature vectors, ex- tracted by a fixed-point arithmetic front-end, together with an interpolation technique for lost vectors, can lead to a 50.48% relative improvement in recognition accuracy. This is achieved at a distance of 10 meters, around the maximum operating dis- tance between a Bluetooth transmitter and a Bluetooth receiver. |
