Voice ID check FAQ

iiNet launched a voice authentication system (Voice ID check) in June 2014 to offer a faster, more secure alternative to the traditional 9-point ID check.


Voice ID check uses voice biometrics to verify your identity over the phone. It matches the unique sound of your voice (your "voice print") to previous recordings of the same phrase. The voice print consists of physical characteristics such as your vocal cords, cadence of speech, nasal passages and duration of your vocal pattern. These characteristics are measured and processed before being turned into a digital format call a spectrogram, which can't be faked by another person.

Your voice print consists of 120 unique checkpoints, which is more unique than a fingerprint. This means it's much more secure than standard question & answer ID check. The technology used by iiNet is able to detect 'liveness' and playback detection to prevent malicous users from bypassing verification using pre-recorded audio. In fact, voice biometrics is so secure it's used by some major banks overseas for authenticating large financial transactions.

Background noise, microphone quality, line and compression quality are some factors which can potentially distort a person's voice. The voice biometrics technology used by iiNet is able to compensate for these and in most cases you can be successfully verified.

In most cases, yes. The hard and fast rule is that if your family can identify your voice, even with a cold, then Voice ID Check will verify you. Because the voice biometrics software uses the physical characteristics of your voice, your verification will be successful in most cases.

If our system is unable to identify your voice on the first go, you'll be able to try again up to 2 more times. In the unlikely event that you still fail, you'll be asked to undergo a traditional 9-point ID check with a Customer Service Rep.

Our Voice ID phrase is: "At iiNet, my voice is my password". Custom phrases are not available.

Yes! Anyone authorised on your account may enroll for Voice ID Check. However, if someone is already enrolled for voice authentication on the account, any additional enrollments will have to be initiated by one of our Customer Service Reps after they have run through a 9-point ID check.

No, you only need to enrol once. As long as your mobile number, home phone number or work numbers are listed on your account, and your numbers aren't blocked (e.g. Silent Number) when you make a call, our phone system would identify your account and trigger Voice ID Check when you call us.

Please note: If your work phone displays the reception or main number rather than your direct phone number when you make a call, our phone system may not be able to identify your account. If this occurs, you'll need to complete a standard 9-point ID check with a Customer Service Rep.

Yes. Our Voice ID Check is opt-out. If you haven't already enrolled, when you call us you'll be asked to enroll in Voice ID Check before you reach a Customer Service Rep. Once you've reached a Customer Service Rep and completed a traditional 9-point ID check, you can ask to opt-out of Voice ID Check. They'll be able to delete any of your existing voice prints at your request.
