Introduction to Automatic Speech Recognition (ASR) - GitHub Pages
The acoustic model is a complex model, usually based on Hidden Markov Models and Artificial Neural Networks, modeling the relationship between the audio signal and the phonetic units in the language. In isolated word/pattern recognition, the acoustic features (here \(Y\)) are used as an input to a classifier whose rose is to output the correct ...
