Unfox analyzes speech patterns and audio signals that may help distinguish AI-generated voices from natural human speech.
Review Your Results
See whether the voice is more likely AI-generated or human, along with a probability score that helps you understand the detection result.
How Does an AI Voice Detector Work?
An AI voice detector analyzes patterns in recorded speech that may differ between natural human voices and AI-generated audio. Unfox evaluates multiple audio signals together and returns a probability-based result rather than treating detection as absolute proof.
01
Analyze Speech and Acoustic Patterns
The detector examines characteristics such as pitch variation, rhythm, pauses, spectral patterns, and other acoustic signals that may reveal synthetic speech.
02
Look for Signs of AI-Generated Speech
AI voice generators and voice cloning systems can leave subtle patterns in audio. Unfox looks for signals associated with synthetic speech instead of relying on a single characteristic.
03
Turn Audio Signals Into a Clear Result
The analyzed signals are combined into an easy-to-read assessment showing whether the uploaded voice is more likely AI-generated or human.
Detect Voices From Popular AI Voice Generators
AI-generated speech can come from text-to-speech, voice cloning, and other synthetic voice systems. Unfox AI Voice Detector analyzes uploaded audio for patterns that may be associated with popular AI voice generation technologies.
01
AI Voice Cloning
Check suspicious audio that may have been created by cloning or imitating a real person's voice with AI.
02
Text-to-Speech Voices
Analyze spoken audio that may have been generated from text using modern AI text-to-speech models and services.
03
Popular AI Voice Tools
Check audio that may come from tools and technologies such as ElevenLabs, OpenAI, Microsoft Azure Speech, Google text-to-speech, PlayHT, and other AI voice generators.

Check interviews, leaked recordings, and submitted audio when the authenticity of a speaker is uncertain.
06
Business Communications
Review suspicious voice instructions, executive messages, and recorded business calls before acting on sensitive requests.
07
News and Viral Audio
Analyze audio connected to breaking news, public figures, or viral claims before treating the recording as authentic.
08
Voiceovers and Creator Content
Check voiceovers, narration, and creator audio for signs that the speech may have been generated or cloned with AI.
Who Uses an AI Voice Detector?
AI voice detection can help individuals and professionals evaluate suspicious recordings and make more informed decisions about whether a voice may be AI-generated.
Individuals
Check suspicious calls, voicemails, and voice messages when you are unsure whether the speaker is real or AI-generated.
Journalists
Review interviews, leaked recordings, and viral audio before using them as sources or publishing them.
Content Creators
Check voiceovers, submitted audio, interviews, and third-party recordings before including them in published content.
Businesses
Review suspicious executive messages, recorded instructions, and business calls that may involve AI voice impersonation.
Investigators
Use AI voice detection as an additional signal when reviewing recordings connected to suspected impersonation or fraud.
Voice Actors
Check suspicious audio that may imitate or reproduce a voice using AI voice generation or cloning technology.
Educators
Evaluate recorded speech for classroom activities, media literacy, assignments, and discussions about AI-generated content.
Moderators
Review user-submitted audio when synthetic speech, impersonation, or manipulated voice content may require closer examination.

AI Voice Detection Accuracy & Limitations
AI voice detection is not a simple true-or-false test. Unfox analyzes patterns associated with synthetic speech and provides a probability-based assessment, so results should be treated as a useful signal rather than absolute proof.
01
Audio Quality Matters
Heavy compression, low recording quality, distortion, or strong background noise can make synthetic voice patterns harder to identify.
02
Clip Length Can Affect Results
Very short recordings may contain fewer speech patterns to analyze. When possible, use a clear clip with enough continuous speech for a more informative assessment.
03
Edited Audio Can Be More Difficult
Pitch changes, speed adjustments, filters, splicing, and repeated re-encoding may alter some of the signals used during AI voice detection.
04
AI Voice Models Keep Evolving
Voice cloning and text-to-speech technologies continue to improve, which means detection methods must also adapt as new generation techniques emerge.
05
Use Results as Supporting Evidence
For important financial, legal, journalistic, or security decisions, combine the AI voice detection result with source verification and other available evidence rather than relying on one score alone.
Handle Voice Recordings With Care
Audio is uploaded to the Unfox service for AI voice detection. Only submit recordings you have the right to use, avoid unnecessary personal information, and review the Privacy Policy before checking sensitive audio.
Detection Purpose
Uploaded audio is submitted for analysis of patterns associated with AI-generated or synthetic speech.
Use Authorized Audio
Only upload recordings that you own or are permitted to analyze, especially for private conversations.
Limit Sensitive Content
Remove or avoid unnecessary personal, financial, legal, or confidential information before uploading audio.
Review the Privacy Policy
Check the current Privacy Policy for details about data processing, retention, and your choices.

FAQ
Frequently Asked Questions
Find answers to common questions about AI voice detection, AI-generated speech, voice cloning, supported audio, detection accuracy, and privacy.
01How can I tell if a voice is AI-generated?
Listen for unusual rhythm, overly consistent delivery, unnatural pauses, or other irregularities, but do not rely on your ears alone. An AI voice detector can analyze acoustic and speech patterns and provide an additional signal about whether the audio may be AI-generated.
02How accurate are AI voice detectors?
Accuracy varies depending on the detector, voice generator, language, audio quality, and editing. Research shows that performance can drop substantially on unfamiliar generators or manipulated audio, so detection results should be treated as probability-based evidence rather than absolute proof.
03Can an AI voice detector detect ElevenLabs voices?
AI voice detectors can analyze audio created with voice generators such as ElevenLabs when the detector has learned relevant synthetic speech patterns. However, performance can vary between model versions, speakers, languages, and audio conditions, so a result should not be interpreted as guaranteed model attribution.
04Can AI voice detectors detect cloned voices?
Yes, AI voice detection can be used to look for patterns associated with synthetic or cloned speech. High-quality voice clones can still be difficult to identify, especially when the detector encounters unfamiliar generation methods.
05Can edited or compressed AI voices still be detected?
They can sometimes still be detected, but compression, background noise, pitch changes, re-recording, and other edits may remove or alter useful audio signals. Cleaner original recordings generally provide more information for analysis.
06How long should an audio clip be for AI voice detection?
Use a recording with several complete spoken phrases when possible. Very short clips provide fewer speech patterns to analyze, which can make the result less informative.
07What audio formats does Unfox AI Voice Detector support?
Unfox supports MP3, WAV, M4A, and OGG audio files up to 20MB. Upload a supported voice recording directly to the detector to begin analysis.
08Can AI voice detectors work with different languages and accents?
AI voice detection can work across multiple languages and accents, but performance may vary depending on how well a language or accent is represented in the detector's training data. Research has found meaningful performance differences across languages and datasets.
09How does Unfox handle uploaded audio?
Audio is uploaded to the Unfox service for detection. Only submit recordings you are authorized to analyze, avoid unnecessary sensitive information, and review the current Privacy Policy for details about processing, retention, and your choices.
10Can an AI voice detector result be used as proof that a recording is fake?
An AI detection score should not be treated as conclusive proof on its own. For legal, financial, journalistic, or other high-stakes decisions, combine the result with source verification, contextual evidence, and professional analysis when appropriate.
