Speech recognition (in many contexts, also known as automatic speech recognition, computer speech recognition or voice recognition) is the process of converting a speech signal to a set of words, by 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).
Defining the Problem
According to "Survey of the State of the Art in Human Language Technology (1997) by Ron Cole et all" Speech recognition is the process of converting an acoustic signal, captured by a microphone or a telephone, to a set of words. The recognized words can be the final results, for such applications as commands & control, data entry, and document preparation. They can also serve as the input to further linguistic processing in order to achieve text formating or speech understanding.
Speech recognition systems can be characterized by many parameters as in the table below.
| Parameters | Range |
| Speaking Mode | Isolated words to continuous speech |
| Speaking Style | Read speech to spontaneous speech |
| Enrollment | Speaker-dependent to Speaker-independent |
| Vocabulary | Small (< 20 words) to large (> 20,000 words) |
| Language Model | Finite-state to context-sensitive |
| Perplexity | Small (< 10) to large (> 100) |
| SNR | High (> 30 dB) to low (< 10 dB) |
| Transducer | Voice-cancelling microphone to telephone |
