About Lexiconic
Lexiconic is a browser-native audio transcription tool built on one principle: your voice recordings belong to you, and only you. There are no servers involved in processing your audio — the entire pipeline runs inside your browser tab.
What it does
Lexiconic converts spoken audio into text. You can use your microphone for live recording or upload an existing audio or video file. It supports over 90 languages with automatic language detection, and can optionally translate any language directly into English.
Who it's for
- Journalists transcribing sensitive interviews without risking source exposure
- Newsrooms converting audio articles and press conferences to text
- Researchers and academics processing recorded fieldwork
- Legal and medical professionals handling confidential recordings
- Content creators and writers turning voice notes into draft copy
How it works
A compact, precision-quantized speech recognition model is fetched from a public model registry on first use and cached in your browser's local storage. All inference runs locally — no audio, transcript, or metadata is ever sent to an external server.
The AI engine operates on a dedicated execution thread, fully isolated from the UI, keeping the interface responsive regardless of file length or device capability.
Accuracy
Lexiconic uses a lightweight model optimised for speed and broad compatibility. Accuracy is high for clear speech in supported languages, and degrades with heavy background noise or strong accents. For critical work, we recommend reviewing the output.
