How Speech Recognition System Works?
means of an algorithm implemented as a computer program. Speech recognition applications that have emerged over the last years include voice dialing (e.g., Call home), call routing (e.g., I would like to make a collect call), simple data entry (e.g., entering a credit card number), and preparation of structured documents (e.g., a radiology report). Speech Recognition system converts acoustic signal, captured by microphone or telephone to a set of words. Recognized words can be final results, as for applications such as commands and control, data entry, and document preparation. They can also serve as input to further linguistic processing in order to achieve speech understanding. There are two types of Speech Recognition Systems: 1. speaker-dependent: user must provide samples of his/her speech before using them. 2. speaker-independent: no speaker enrollment necessary. External parameters can affect speech recognition system performance: characteristics of environmental noise, type and
