What Is an AI Voice Detector?
An AI voice detector is a tool that analyzes audio recordings to determine whether the voice or speech was generated by artificial intelligence or spoken by a real human. With AI voice cloning technology advancing rapidly — services like ElevenLabs can clone a voice from just 3 seconds of audio — detecting synthetic speech has become essential for security and trust.
Our free AI voice detector uses advanced spectral analysis, vocal biomarker detection, and machine learning to identify deepfake audio with high accuracy. Whether you received a suspicious voice message, need to verify a phone recording, or want to check if podcast audio is authentic, our tool provides fast, reliable detection.

Frequently Asked Questions
How does the AI voice detector work?
Our detector analyzes vocal patterns, frequency spectrum, speech cadence, breathing patterns, and other audio biomarkers that distinguish AI-generated speech from real human voices. It uses machine learning trained on millions of both AI-generated and real audio samples.
What AI voice generators can it detect?
Our tool can detect synthetic voices from ElevenLabs, OpenAI TTS, Google WaveNet, Amazon Polly, Microsoft Azure Speech, Murf AI, PlayHT, and other popular AI voice generators.
Can AI-generated voices really be detected?
Yes. Despite advances in AI voice synthesis, AI-generated audio still contains detectable artifacts in spectral patterns, micro-intonations, and breathing dynamics that differ from natural human speech.
What audio formats are supported?
We support MP3, WAV, OGG, AAC, FLAC, M4A, and WebM audio formats. Maximum file size is 20MB. For best results, use recordings with clear audio and minimal background noise.
How accurate is the AI voice detection?
Our AI voice detector achieves high accuracy on most AI-generated voices. However, heavily processed audio or recordings with significant background noise may affect results.
Can it detect deepfake voice calls?
Yes, our detector can analyze recorded audio from phone calls, voice messages, and other sources to determine if the voice is real or AI-generated.
Is this AI voice detector free?
Yes, our AI audio and voice detector is completely free to use with no sign-up required. You can analyze as many audio files as you need.
How to detect if someone is using a voice clone?
Upload a recording of the suspected voice clone to our detector. The AI will analyze vocal biomarkers, spectral consistency, and speech patterns to determine if the voice is a real human or an AI-generated clone.
Can it detect AI voices in phone calls?
Yes, if you have a recording of the phone call. Record the suspicious call (where legally permitted) and upload the audio file. Our detector analyzes vocal patterns even in lower-quality phone audio. This is especially useful for identifying voice cloning scams targeting family members.
What is the difference between voice cloning and text-to-speech?
Text-to-speech (TTS) generates speech from text using a generic or customized voice model. Voice cloning creates a digital replica of a specific person's voice from audio samples. Our detector can identify both types of AI-generated audio, as both leave detectable artifacts in spectral patterns and vocal dynamics.
