Video transcription is the process of converting all the audio in your video to text. You can do it either manually or using an automatic speech recognition tool.
Why do you need to turn all the audio of your video into text? Well, the answer is simple. Sometimes your audience finds it hard to follow your speech, so having the written version helps them out.
The subtitles you see on Youtube videos, for instance, serve that purpose and are generated through transcribing.
Of course, you can go ahead and transcribe your file manually by writing down EVERY SINGLE WORD, but we know that it's way too time-consuming. So we'll tell you how to work more efficiently by transcribing your files using AI-powered technology. But before that, let's go through the:
Main transcription types
There are several transcription types, depending on the precision level you want to get:
- Verbatim is the word-for-word transcription when you write down the words exactly in the way you hear them. This means you do not remove filler words or false starts and do not make grammatical corrections.
- Intelligent verbatim transcription implies that you should clean the filler expressions, repeated words, and other sounds that are not relevant to your main speech. Intelligent verbatim is also referred to as clean transcription.
- In the case of true verbatim transcription, you should go beyond words and transcribe everything you hear, including laughter, applause, and ambient sounds.
Why do you need a video transcription
If you wonder why you should spend additional time and effort to make a video transcription, here are a couple of reasons:
#1 Better comprehension
Reading and listening to the same text simultaneously makes the idea better understood and remembered. That's why the majority of educational videos are usually accompanied by textual content.
Besides, captions decrease the language barrier issues. Many non-native speakers might find it hard to understand spoken English but will have no problem understanding the written subtitles.
Also, simultaneous reading and listening help improve the language proficiency level, as it exercises the listener's pronunciation and grammatical skills.
That's why watching videos with transcriptions is usually the critical activity for many language courses.
#2 Better accessibility
Unless legally restricted, you want your content to be equally accessible for all the different social sectors. So as not to discriminate, always include video captions for deaf or hard-of-hearing people.
More than 360 million people worldwide have hearing disabilities, and you don't want to lose so many potential customers.
In this way, you will also comply with legal regulations, as anti-discrimination laws in many countries require you to provide different social groups with equal access to information.
#3 SEO optimization
Alas, at this point of technological development, Google can't watch the video and understand what you are talking about. However, communicating your video content to Google is essential for the promotion goals.
By adding transcription, you help Google bots to analyze what your video is about thoroughly. If you research for the right keywords and correctly use them in your script, you'll end up having better Google rankings.
Most importantly, transcriptions increase your video's searchability, as having accompanying text will allow your target audience to find your content more easily.
How to make a video transcription?
Simply typing anything you hear in the video sounds pretty straightforward. However, as we've mentioned, it is a time-consuming task that requires patience, attention to detail, and high language proficiency.
So, let's categorize the options you have for transcribing the video: manually and automatically.
If you are fond of detailed manual work and know the transcribing language well enough, go ahead and do it manually.
But if you choose to do transcription manually, make sure you clearly understand how much time it will take for you. Usually, experienced specialists transcribe 1 hour of the video in 2-3 hours, depending on how noisy the video is, the number of speakers, and the audio quality.
If you are a newbie in this field, set longer deadlines. Estimate approximately 4 or 5 hours for transcribing each hour of the audio.
If you don't want to get into much hassle and want to get your transcription in less than a minute, use the automatic transcription
Not only is automatic transcription fast and convenient, but it's also inevitable in some cases.
For example, if you don't know the language spoken in the video or need transcription for a 7-8 hours' video as soon as possible, you have no other choice than to leave it to the AI.
How reliable is automatic transcription?
Technology continuously improves, but the chances are low that it will ever turn into a real human. So, in any case, run the automatically transcribed text in a grammar checker or proofread it yourself to have a high-quality transcription.
However, modern automatic speech recognition systems are really good as they usually require minor edits in the end. Most of them are regarding the specific terminology or newly introduced words.
