Security of your application is important and if not
controlled properly it can lead to problems. Voice verification
allows you to have part of your line protected. Whilst the call is in
progress you might want some control over who can access certain areas,
or connect to a remote site etc.
Using Voice Verification we can ask the caller to say a phrase or
spoken word that we will recognise to be right or wrong. Being right
would allow the caller to access the area, being wrong would deny access.
We can perform the following checks on a spoken voice:
- Voice tone, being male or female voice.
- Voice accent (if they have one)
- Voice dialect, a good give away.
- Voice volume, how loud they spoke.
All the factors above go into the screening process of
allowing someone to access an area or not. A simple 2 minutes
training process with a new voice is all we ask to add another
user to the system.
But there is not just a yes or no that can be verified, we can
look for spoken phrases like "call me at home please" or "lights on",
maybe you have seen Back To The Future 3? Well this is for real. Using
registered phrases we can perform any task you require. We simply
recognise what you're asking for and execute that command immediately.
We can also ask you to verify your request in case accidental instructions
have been given.
How does it know new voices?
Once you add a new user we will ask them to speak out a common sentence
twice over the telephone, once we have analysed the voice we will save
it into the security database so you can use it for access.
How many voices can it detect?
When we listen to a voice, we don't just listen to the sound, a lot
of factors go into the general makeup of the human voice, so by using our
training method we are not detecting a new voice from old, we are simply
comparing it to the voices that have already been trained into the system.
Security issues
Most of the time voice verification is secure enough to stop access to
other areas, however, if your application needs a greater level of
security then we don't recommend using this as "front line" security.
Most customers have several phases the caller has to get through before
being allowed onto the system, like entering a pin number first, then a
4 digit random number followed by the voice verification. This setup would
commonly be used by telephone banking systems for example, or somewhere
else where money is involved.
What can I use this feature for?
Having these features is great but when will you get the chance to
use them without making the call too complicated so the caller hangs
up confused. Here are some examples:
- Access to on-line banking, move money from different
accounts for example you could speak out "transfer one hundred
pounds from account 53900902 to 53200903"
- Access a secure area
