The AI voices in this test were generated using various publicly accessible text-to-speech and voice cloning models. The AI audio has not been edited in any way and was left as-is. Additional editing could enhance the realism or correct imperfections inherent to the initial generation process, potentially making it more challenging to distinguish between AI-generated and genuine voices.

Telling if a voice is AI-generated can be very challenging.

AI voices have become remarkably realistic, and most people struggle to reliably tell them apart from real human voices.

How can you tell if a voice is AI generated?

  • Listen for unnatural intonation and rhythm — AI voices can sound slightly too smooth, too even, or oddly paced.
  • Pay attention to breathing and mouth sounds. Real recordings often include subtle breaths, lip smacks and background noise that AI may omit or reproduce imperfectly.
  • Notice emotion and emphasis. AI can place stress on the wrong words or fail to convey natural emotion.
  • Listen for artifacts — metallic tones, glitches, or abrupt transitions between words can reveal synthetic audio.

AI can help.

Our automated AI voice detection tool can help you determine whether a voice recording is real or AI-generated.
