As we can consider that music is a kind of language, the language recognition approach could be used for music recognition:
- get data (speech signal / musical signal)
- extract reliable features (dynamic, spectrum, ceptrum, ...)
- model (diagrams, trees, neural networks...)
- compare (expected text in a dictionnary / expected sequence in a score)
Furthermore, as a speaker adaptation is used in speech recognition systems, we can have an instrument adaptation in music recognition system, in order to improve the acuracy of the matched performance.
The speech recognition approach has been already used for the HMM score Following described above.
