What is Audio Transcription?
Audio transcription is the process of converting spoken words from an audio recording into written text. Whether you need to transcribe meetings, podcasts, interviews, lectures, or voice notes, NovaScribe helps you turn audio files into accurate, searchable, and editable text documents in minutes.
Instead of manually typing out hours of recordings, our AI-powered speech-to-text technology listens to your audio and automatically generates a transcript. The result includes timestamps for easy navigation, speaker labels when multiple people are talking, and the ability to export in various formats for your specific needs.
NovaScribe supports common audio formats like MP3, WAV, M4A, and FLAC, making it easy to upload recordings from any device or platform. If you're working specifically with MP3 files, you can also use our MP3 to Text. Simply upload your file, let the AI process it, and download your transcript—no technical expertise required.

High Accuracy Transcription
Our transcription system is trained on diverse audio sources including meetings, podcasts, lectures, and interviews. This helps deliver reliable results even with different accents, speaking styles, or technical vocabulary.
