How Speech Recognition Works
Speech Engines Use This Process to Figure out What a Speaker Said:
The engine loads a list of words to be recognized. This list of words is called a grammar.
Audio from a speaker is captured by a microphone or telephone. This audio is turned into a waveform, a mathematical representation of sound.
The engine looks at features — distinct characteristics of sound — derived from the waveform and compares them with its own acoustic model. The engine searches its acoustic space, using the grammar to guide this search.
It then determines which words in the grammar the audio most closely matches and returns a result.
