| Abstract: | The unequal error protection (UEP) is applied in distributed speech recognition (DSR) system and three schemes are proposed. All of these three schemes are evaluated on the GSM simulating platform for recognizing mandarin digit strings and compared with the equal error protection (EEP) scheme. Experiments show that UEP can protect the data transmitted in DSR system more effectively, which results in a higher word accurate rate of DSR system. |
