Is Voice Harbor for me?

Answer these questions to find out

1 | Do you ever record or publish interviews where the speaker’s identity must remain confidential — but their real voice still goes on air?

2 | Are you manually distorting or masking voices (pitch-shifting, filtering, or re-recording) and struggling to maintain clarity or emotion?

3 | Do legal or compliance teams ever flag concerns about GDPR or biometric data exposure in your audio workflows?

4 | Have you ever held back a powerful story, testimony, or dataset because it could reveal someone’s identity through their voice?

5 | Do your journalists, producers, or analysts spend valuable time anonymizing sensitive audio — instead of focusing on the story itself?

If you answered yes to any of these...

Voice Harbor is built for you. We help you secure your audio data, stay compliant, and unlock its full potential.
