What is Speaker Verification
Speaker verification, also known as speaker recognition, can be defined as process of authenticating ones claimed identity by comparing their voice and previously recorded or computed speech characteristics (voiceprint, which is as unique as finger print ). While speech recognition is widely used in IVR, speaker verification or recognition is different than speech recognition and is relatively recent addition to numerous usage of IVR systems.
Speaker verification is one of the recent and advanced IVR feature which is increasingly being used some IVR applications where personal identification is very important, for example, Banking, attendance registration etc.
How it can be used in IVR ?
As the name suggests, speaker verification is essentially used for authentication a IVR caller to manage his account. Since now, IVR systems have been authenticating its caller with ‘password’ or PIN ( Personal Identification Number) by pressing telephone keys or DTMF or even speech recognition.

Voice portal services in India are one of the most successful VAS ( Value Added Service) in terms of revenue generation. Voice portal is steadily growing in India. Voice Portal operators like OnMobile, One97, Cellebrum ( Now Spice Digital), IMI Mbile, Rajasthan Patrika, etc. are few players who are spearheading the voice portal growth in India. Presently, voice portal services in India normally work on a “short code” ( short dialing number for users) and ‘users-pay-per-minute-of-usage’ basis.
Voice portal is set to continue growing in near future despite its high cost to users ( ( Rs. 6 per minute, while normal voice call in India is now as low as 45 paise per minute). It is also expected that the price will come down with introduction of subscription model, where voice portal users subscribe to its service and can avail at much lower rate that Rs. 6 per minute.

IVR (Interactive Voice Response) system can do many things and one of the most common task it performs is “Call Transfer”. Both inbound and outbound IVR may transfer the active call to some other telephone number or human agent once the IVR user chooses.
Though in a call center environment, human agent may get information about the caller in a POP UP window in its desktop PC, but when call is transferred to any telephone number, this kind of POP UP window with caller information may not be available! But, IVR may surely do a “Value Added Call Transfer” by announcing caller details in voice! It may even offer the transferee the option reject or divert to voice mail, transfer to another telephone number! In PBX terminology, it is called Call Whisper or Call Screening and when IVR implements it, we may surely call it “Value Added Call Transfer”.
How to Implement Value Added Call Transfer :
Implementing value added call transfer with IVR is quite, may be simple extension of any existing call transfer. It can be implemented using both analog and digital CTI card. While implementing value added call transfer, “bridged call transfer” would be employed using two channels.

One of the major problem faced by any IVR developer using analog CTI board is “Detecting Disconnect” after call is hung up by IVR caller. With different disconnect tones used by different PBX manufacturer does not help either.
Detecting Call End or Disconnect is very easy while using digital CTI board with digital interfacing like ISDN, SS7 etc., but detecting DISCONNECT is not that straight forward or easy while using analog CTI boards. It is mainly because of exchanging “control information” with analog technologies!
There are few techniques or information using which DISCONNECT event can be detected and Call End process can be initiated in any CTI application:-

IVR ( Interactive Voice Response) system has many usage in different industries for different purpose,and IVR can also be used for any kind of “registration process” across industries! One may find it interesting, IVR for complaint management is also part of a larger “registration process”!
IVR Registration
There are requirement of prior registration for various events like seminar, exhibition, events, presentation. IVR provides simple registration process where any willing participants has to just dial one telephone number, press one key and he is registered! IVR can detect caller ID as the phone number of the caller and with increasing use of mobile phone, phone number is almost as unique as any identity!
