How to Convert Audio to Text Transcripts

Converting audio to text transcripts is an extremely useful skill in the digital age. Whether you need to transcribe an interview, meeting, podcast, or other audio content for work, or you simply want to increase the accessibility of your audio files, having accurate text transcripts is invaluable.

In this comprehensive guide, we will cover everything you need to know about transcribing audio to text efficiently and accurately.

Why Transcribe Audio to Text?

Here are some of the top reasons for converting audio to text transcripts:

  • Increase accessibility – Text transcripts make audio content accessible for those who are deaf or hard of hearing. They also make it easier for people to skim and search audio content.
  • Repurpose content – Once you have a text transcript, you can easily repurpose the content into blog posts, social media updates, and more.
  • Improve SEO – Text content is much easier for search engines to index than audio files. Adding transcripts helps boost your website’s SEO.
  • Save time – Reading a transcript is faster than listening to an audio recording. Transcripts make it easy to quickly find and refer back to information.
  • Aid analysis – Text transcripts can be run through text analysis tools to extract key themes, concepts, and useful data.

Methods for Audio Transcription

You have a few options when it comes to transcribing audio files to text:

Manual Transcription

This involves listening to the audio recording while manually typing up a transcript. It is time-consuming but allows you to transcribe audio with high accuracy. Manual transcription takes at least 3-4 times the length of the audio file.

Automated Transcription

Automated transcription uses speech recognition technology to automatically convert speech to text. It is much faster than manual transcription but accuracy can vary greatly depending on audio quality. Many services offer automated transcription including Otter.ai, Trint, and Descript.

AI-Assisted Transcription

This hybrid model combines automated speech recognition with human editing to boost accuracy. Services like Rev and GoTranscript use AI to create an initial draft transcript which is then edited by human transcribers. This combines speed and accuracy.

Choosing the Best Method

The best transcription method for you depends on your budget, audio quality, need for accuracy, and turnaround time. Manual and AI-assisted transcription provide the highest accuracy but are more expensive and time-consuming. Automated services are affordable and extremely fast but have lower accuracy.
