    Consider the following statements
    1. Speech recognition is very useful for people with disabilities.
    2. Acoustic Modelling and Language Modelling are important parts of speech recognition algorithms. Which of the statement(s) given above is/are correct?

    A)  Only 1

    B)         Only 2

    C)  Both 1 and 2    

    D)  neither 1 nor 2

    Correct Answer: C

    Solution :

    [c] Some Speech Recognition systems use "training" (also called "enrollment") where an individual speaker reads text or isolated vocabulary into the system. The system analyses the person's specific voice and uses it to fine-tune the recognition of that person's speech, resulting in increased accuracy. Systems that do not use training are called "speaker independent"[1] systems. Systems that use training are called "speaker dependent". An acoustic model is used in Automatic Speech Recognition to represent the relationship between an audio signal and the phonemes or other linguistic units that make up speech.
