The speech recognition module, for exam- ple, was originally implemented by our LPNN, described in Chapter 6 (Waibel et al 199 1, Osterholtz et al 199 2); but it was later replaced b...

This architecture was initially developed for phoneme recognition (Lang 198 9, Waibel et al 198 9), but it has also been applied to hand- writing recognition ... performance. We will see that neural networks help to avoid this problem. 1.2. Neural Networks Connectionism, or the study of artificial neural networks, was initiall...
