Robocalls are unwanted calls made by machines. Some are useful, like reminders from a doctor. But most are scams. Fraudsters pretend to be banks, telcos, or even family to steal money or information. Billions of robocalls happen each year. Many people and businesses lose money because of them.
What Is a Robocall?
A robocall is an automated phone call with a prerecorded or fake voice. A robo caller is the person or system sending these calls. With new AI tools, these voices now sound almost human. Some are even cloned from real people. That makes it hard to know who is calling.
Why Do You Get So Many Robocalls?
Robocalls are cheap. Fraudsters can send thousands of calls at once. Even if only a few people fall for them, the scam is profitable.
Why am I getting more spam calls now?
- Your number may have leaked in a data breach.
- Criminals use AI to create cloned voices.
- Caller ID is easy to fake, so blocking tools don’t always work.
How to Block Robocalls
You can block calls on your phone, with your carrier, or with apps.
On iPhone
- Go to Settings > Phone > Silence Unknown Callers.
- Use Focus modes to allow only trusted contacts.
- Install a spam filter app from the App Store.
On Android
- Turn on Caller ID and Spam Protection in settings.
- Mark calls as spam to improve filtering.
- Use third-party apps for stronger blocking.
Through your carrier
Most carriers offer spam filters. Some are free, some paid.
Delete vs block
Deleting a call does nothing. Blocking prevents repeat attempts. Always block.
Why Blocking Alone Is Not Enough
Fraudsters now use AI to create fake voices. They can also replay recordings. These tricks bypass normal defenses. Caller ID spoofing makes fake calls look real. Simple blocking cannot stop these scams.
Voice Biometrics: A Better Way
Voice biometrics checks the unique features of a person’s voice. It can tell if a voice is real or fake. Veridas has built Voice Shield, which:
- Detects deepfakes and synthetic voices.
- Catches replayed voices from speakers.
- Authenticates people in under 3 seconds.
- Works in any language, with natural speech.
Privacy
Veridas does not store voices. It uses Renewable Biometric References (RBRs). These are mathematical codes, not recordings. They cannot be reused or shared. If one is compromised, it can be replaced. This ensures privacy and compliance with GDPR and other laws.
Real Use Cases
- ONCE & ILUNION in Spain: More than 80% of vendors use voice each day to log in. It is secure and simple.
- Pensions in Mexico: Over 175,000 pensioners prove they are alive by phone. They only need three seconds of speech. No travel, no risk.
These examples show that voice biometrics are safe and easy to use.
FAQs
Can Voice Shield detect deepfakes?
Yes. It has been tested by NIST and iBeta. It detects synthetic and replayed voices.
Does voice authentication make calls harder for customers?
No. It is passive. People just talk as normal. No passwords or PINs.
Are voices stored?
No. Only encrypted references (RBRs) are kept. They cannot be reversed or reused.
What if someone’s voice changes?
The system adapts to natural changes from age, illness, or accent. RBRs can also be updated.
Is this worth the cost?
Yes. Robocall fraud costs billions each year. Voice Shield reduces fraud, lowers call times, and cuts false positives. This saves money.
Final Thoughts
Blocking robocalls with phone settings and apps is a good start. But it will not stop advanced scams. AI voices and spoofing can trick these tools. The real solution is to check if a caller’s voice is genuine.
Voice Shield by Veridas makes this possible. It helps businesses and users:
- Stop AI-powered fraud.
- Secure every call.
- Save money and build trust.
