ExperimentSec92_AnechoicSpeechSignal.wav:
Source signal used for experiments in Sec. 9.3

ExperimentSec92_ObservedSignal.wav:
Reverberant signal used for experiments in Sec. 9.3

Speech_AnechoicSpeechSignal.wav:
Anechoic speech signal from the TIMIT database, down-sampled from 16kHz to 4kHz. No changes made otherwise.

Speech_ReverberantSignal.wav:
The speech signal was distorted by WGN varying according to a random walk and normalised to 35dB SNR. The resulting noisy signal was filtered by the 8-th order time-varying channel with circular poles. Segmental SRR: -5.5485dB

Speech_MARBLEEstimate.wav:
The speech estimate acquired by the MARBLE particle filter using the Markov chain based model with a model order of Q = 15 and 2000 particles. The SRR is improved by approximately 3dB to -2.9718dB. The metallic effects due to the channel are partially removed in the very beginning and towards the end of the signal. However, the signal quality cannot be recovered in the middle of the speech sequence.
