Electronic Voice Phenomena (EVP) recording and analysis tool. Uses your device's microphone and the Web Speech API to continuously transcribe any detected audio — including your own voice and any ambient sounds or anomalous responses.
For best results, use headphones to prevent feedback, record in a quiet environment, and speak your questions clearly with pauses between them to allow for potential responses.
This tool uses your browser's built-in Web Speech API for transcription. No audio data is transmitted to external servers or stored. EVP research remains scientifically controversial — transcriptions may reflect ambient noise, pareidolia, or speech recognition artifacts rather than anomalous phenomena. Use as an experimental research tool.
