Speech Recognition

Description: A wide variety of techniques are used to perform speech recognition. There are many types of speech recognition. There are many levels of speech recognition / analysis / understanding.

Typically speech recognition starts with the digital sampling of speech. The next stage is acoustic signal processing followed by the recognition of phonemes, groups of phonemes and words.

Most systems utilise some knowledge of the language to aid the recognition process.

Some systems try to "understand" speech. That is, they try to convert the words into a representation of what the speaker intended to mean or achieve by what they said.
