21.   But getting speech systems into small devices means overcoming size and power constraints.

22.   Carnegie Mellon has its own speech recognition system, CMU Sphinx, which is similar to commercially available speech recognition systems for dictation programs, he said.

23.   Comerford said that the protoype was based on three decades of work by IBM scientists to create increasingly nimble programming codes for speech systems.

24.   Continuous speech recognition systems are also available from Philips Electronics NV and Dragon Systems Inc.

25.   Given the wide variations in accent, pace and clarity in human speech, the best speech recognition systems get a significant percentage of words wrong.

26.   IBM, another m-commerce cheerleader, is developing a speech recognition system that could be used for wireless purchases.

27.   Industry analysts expect continuous speech systems, like the one IBM is expected to unveil tomorrow, to vastly expand the market for speech recognition products.

28.   It is far from perfect, but it is nonetheless the first speech recognition system I would seriously consider using in my work.

29.   One is in an extremely sophisticated speech recognition system, which understands complex sentences, not just words.

30.   Recent advances in getting personal computers to recognize words and numbers have started to reduce the complexity of using speech systems.
