Very often speech recognition telephony applications such as Voice Response Systems (VRS) ask a caller to input alphanumeric information for their process. However, it is very inconvenient if the caller has limited display and input capabilities. Also, if one of the characters go wrong, complete call has to be repeated. Hence, there is a need of replacing this alphanumeric input to voice recognition systems. However, background noise and distortion is a hurdle in this area of development.

Nice Idea. Noise removing techniques can be helpful in this case.
ReplyDeleteSmoothing filters such as Comb or Adaptive filters can be used for noise reduction as well.
DeleteCan be prospect for future VRS systems.
ReplyDeleteNot only VRS systems, these can be used for speech recognition in security systems and home automation as well.
Deletevery informative
ReplyDeleteFurther information is easily available on net
DeleteAdaptive noise filters can be designed to improve system performance.
ReplyDeleteYes, IIR filters can be used as they have feedback mechanism
DeleteQuite useful
ReplyDeleteYes, it can be used in real time
DeleteGood application.It's used in cellphone.
ReplyDeleteIt can also be used in home automation systems.
DeleteVoice recognition system if placed in a low- noisy environment will work well! And hence background noise might not affect it
ReplyDeleteSmoothing filters such as Comb or Adaptive filters can be used for noise reduction as well.
DeleteThis approach may put restrictions on the usability of the system
DeleteIt can be used in industries as well.
ReplyDeleteYes, extreme fields such as power electronics too uses it.
DeleteCan replace existing technologies
ReplyDeleteYes, it is still a technology to look forward to.
