A telecommunication system and method having a transmitter and receiver for voice encoded signals. The receiver has a speech post-processor connected as an element before conversion of the speech from digital form and delivery of the speech to a listener. The speech post-processor processes select sequences of speech signals of a predetermined duration, and obtains the most likely estimation of a speech sequence that contains unrecognized phonemes. The speech post-processor has a recognizer and parser that receives speech signals, parses them into corresponding phonemes or unrecognized phonemes. Speech sequences of preselected duration are selected, and processed through an execution trellis implemented by a Viterbi algorithm to obtain a most likely sequence estimation for sequences which contain unrecognized phonemes, and determined phonemes replace the unrecognized phonemes. Only speech sequences with unrecognized phonemes are directed to the execution trellis. Following processing, the speech sequences are re-combined in time order.
A telecommunication system including a wireless transmitter and wireless receiver for voice encoded signals, said wireless receiver comprising a digitally operated speech post-processor connected as an element before conversion of the speech to analog form and delivery of the speech to a listener, said speech post-processor digitally processing speech signals and obtaining a most likely estimation of at least one speech sequence containing at least one unrecognized phoneme;
A device for effecting telecommunications comprising a wireless receiver, said wireless receiver including a digitally operated speech post-processor connected as an element before conversion of the speech to analog form and delivery of the speech to a listener, said speech post-processor digitally processing speech signals and obtaining a most likely estimation of at least one speech sequence containing at least one unrecognized phoneme;
