Why Choose VoxGuard?

Complete call protection that goes beyond simple blocking

Automatic Call Screening

Unknown callers are intercepted before your phone rings. They're routed to VoxGuard where they must pass verification and state their reason for calling — all before you're ever interrupted.

Human Verification

Callers are asked to repeat a word or phrase that you define — it can be anything you want. Real people hear it and respond; robocalls and spam bots can't. Three failed attempts and the call ends automatically.

Recorded Reason & Transcription

After verification, callers record why they're calling. VoxGuard transcribes it to text automatically, so you can read it at a glance or play back the full audio recording.

Approve or Decline in Real Time

Your phone rings the moment the caller is ready. Tap the notification, review their recorded reason, and approve to connect or decline to end the call — you have a 2-minute window.

Smart Voicemail

Missed or declined calls go to voicemail. Set different greetings for known callers vs. screened callers — use text-to-speech or record your own voice. Every voicemail is transcribed automatically.

Caller Audio as Ringtone

When auto-play is enabled, your phone plays the caller's actual recorded reason as the ringtone when a screened call is ready. Know why they're calling before you even pick up the phone.

How VoxGuard Works

See the screening process step by step

1

Unknown caller is intercepted

An unknown number calls your phone. The call is automatically routed to VoxGuard for screening. Your contacts bypass this entirely.

2

Caller must say your key phrase to verify

VoxGuard plays a message telling the caller what word to say. Real people hear it and repeat it. Robocalls and automated spam can't respond to voice prompts.

VoxGuard: "This call is protected by VoxGuard. To proceed, please say blueberry."
3 failed attempts = call ends. Screens out robocallers automatically.
3

Verified? They state their reason for calling

Callers who pass verification are asked to record why they're calling. The recording is automatically transcribed to text.

VoxGuard: "Please state your reason for calling."
4

You get notified and listen to their reason

A push notification hits your phone with the caller's number. Tap to open the call detail screen — play the audio waveform and read the transcript.

5

Approve to connect, or decline to end the call

You have a 2-minute window to decide. Approve and the caller is connected to your phone. Decline and the call ends. Miss it and the caller goes to voicemail.
