Abstract :
In this work, we investigated performance improvement of the distributed Turkish continuous speech recognition system (TCSRS) with some well-known packet loss concealment (PLC) techniques. The PLC techniques, Lagrange, Spline and maximum a-posteriori (MAP) are applied to the sparse and burst packet losses in the system. The experimental results showed that the interpolation methods give acceptable performance during sparse packet losses. But for burst losses, the performance of MAP estimation method is better than that of interpolation methods.
