AdvantagesSpeech is a very natural way to interact, and
it is not necessary to sit at a keyboard or work with a remote control.
No training required for users! Assist persons with disabilities who may be
vision impaired by reading text

DisadvantagesEven the best speech recognition systems sometimes make
errors. If there is noise or some other sound in the room (e.g. the television or a kettle boiling), the number of errors will increase.
Speech Recognition works best if the microphone is close to the user (e.g. in a phone, or if the user is wearing a microphone). More distant microphones (e.g. on a table or wall) will tend to increase the number of errors.
But speech recognition but the recognition fails because it requires preprocessing after acquiring of speech. The system requires training of voice because of the purpose of it should recognize the correct voice of that user. Suppose user A having this system in his mobile his voice should be train so as to get correct recognition of text.
