Lecture to text with Speech2Text helps you turn classroom recordings, online courses, and conference talks into readable notes. Instead of replaying the whole session and typing everything by hand, you get a clear transcript that is easy to review, highlight, and share.

To convert an audio lecture to text, simply upload your recording to the site. You can use files from a phone, laptop, or meeting app. Select the language and, if needed, the number of speakers, then start recognition. The system will transcribe the lecture, break it into paragraphs, and restore punctuation so you receive text that needs minimal editing.

Useful features for lecture transcription

Noise reduction for lecture halls

Lecture rooms often have background noise: chairs moving, side conversations, air conditioning. After upload, the service automatically reduces noise and focuses on the main voice. As a result, you get a lecture to text transcript where important details are not lost in the background.

Recognizing lecturer and students

In many classes, both the lecturer and students speak. Speech2Text can recognize different speakers on the recording. This makes it easier to see where the instructor is explaining concepts and where students are asking questions, which is critical when you transcribe lectures to text for study or review.

Support for multiple languages and accents

Courses and guest lectures are often delivered in English with various accents or in other languages. Speech2Text supports more than 90 languages and accents and can automatically detect the language of the recording. Even technical terms in audio lecture to text transcription are captured with high accuracy.

Timestamps for quick navigation

When you transcribe a lecture, timestamps help you jump back to specific moments in the original audio. You can quickly find the explanation of a formula, an example, or an answer to a question, without manually searching through the entire file.
