What to Do If Your Speech Is Unclear During Binance Video Verification
If you see a prompt saying "cannot recognize the voice in the video," it usually means the recording environment has too much background noise, your voice is too quiet, or you are speaking too fast. The system can't clearly capture and match the verification code or declaration you're reading aloud.
This is a common technical issue with video verification, and it can usually be resolved by adjusting your recording conditions.
Prerequisite: Understand Binance's Voice Recognition Logic for Video Verification
Binance's video verification (whether it's a live video call or an automated liveness check) requires that the system or support agent can clearly hear the required script you read aloud. According to relevant technical documentation, the system analyzes the similarity between the voice in your video and the verification code. If the audio quality is too poor, the volume too low, or there is too much interference, it will be judged as "unrecognizable."
Step 1: Check and Improve Your Recording Environment
What to do: Before re-recording, make sure your environment meets basic requirements.
How to do it:
Ensure a quiet environment — Find a room free of background noise (e.g., TV, wind, other people talking).
Test your microphone — Check your microphone is working in your device settings. Make sure nothing is blocking the microphone hole when recording.
Speak closer to the mic — Keep your mouth 15–30 cm (6–12 inches) from the microphone, and speak clearly at a steady pace.
When you're done: Record a short test clip and play it back to confirm the audio is crisp and clear.
Step 2: Pay Attention to How You Speak
What to do: Follow Binance video verification requirements and read the specified declaration clearly.
How to do it:
During a video call, you need to read the statement out loud—this is a standard requirement.
If you are in a live video call with support, the Binance team will evaluate whether your speech is clearly recognizable.
Slow down, pronounce each word clearly, and avoid mumbling or speaking too fast.
If you're not confident in English, you can speak in your native language, but you must also hold up a piece of paper with the English declaration and your ID document in front of the camera at the same time.
When you're done: You have read the entire declaration clearly, and on playback each word is easy to understand.
Step 3: If the Problem Occurs During Non‑Real‑Time Recording
What to do: If you're submitting a self‑recorded video, pay attention to the error code prompt.
How to do it:
If you receive error code 216509 (cannot recognize the voice in the video), it means the audio quality in the video is too poor—likely due to low volume or background noise.
Re‑record the video, focusing on the environment and speaking tips from Steps 1 and 2.
For steps that involve a voice verification code, the system compares the spoken code with the correct code. Make sure you read the correct digits and that the similarity meets the system threshold.
When you're done: The submitted video has no background noise, and the spoken content is clear and complete.
Common Reasons for Failure
Microphone permission not granted or device muted: Before recording, check that the sound and microphone are enabled and that the browser or app has microphone permissions.
Voice verification code read incorrectly: The system matches the speech recognition result against the real code. An incorrect code or low similarity will cause failure.
Too much background noise: Multiple people talking, traffic noise, or other ambient sounds can interfere with voice recognition.
Risk notice
Do not use screen recording software to record your video. Binance explicitly requires that the video be recorded live and in real time; screen recordings are not accepted.
Do not edit or trim your video after recording. Edited videos will be considered invalid.
Cryptocurrency exchanges typically retain users' verification video records for compliance audits and dispute resolution.
How to Confirm You've Done It Correctly
After re‑recording and submitting your video, if the verification is successful, Binance will notify you via email or in‑app message that your "identity verification has been approved." If you receive another failure notice, check the specific error code or reason in the notification, troubleshoot using the steps above, and try again. If you still fail after multiple attempts, you can request manual assistance through Binance's official live chat. The support team will schedule a video call with you.
