Transcriptions for Educators


Whether you’re a teacher looking to help your students learn better, or a student looking to enhance your study skills, transcriptions can help. Text transcripts, as well as closed captions, help individuals learn better by improving comprehension and retention rates. Transcripts also provide an extra study tool for students and improve learning for foreign-language and hard-of-hearing individuals.

Transcriptions for Businesses


Businesses are hosts to a wide range of content that needs to be transcribed. Recorded interviews, meetings, and conferences often need to be accurately transcribed to keep an easy record of what was said. Marketing material also needs to be transcribed as a text document and as closed captions in order to ensure that the intended audience is able to access the content no matter their circumstances.

Transcriptions for Creators


The world of online content is booming, with more podcasts, YouTube channels, and documentaries being made now more than ever. To access a wider audience, all of this content needs to be transcribed. These transcriptions and closed captions can also boost SEO performance and allow creators to acheive more success in a competitive online space.

Transcriptions for Religious Organizations


Many religious organizations are using video and audio content to share their message online with a larger audience. Recorded sermons and services can be easily transcribed and captioned using SubCaptioner to ensure that the messages are accessible to everyone, including those with hearing loss or who speak a second language. Transcribing content with SubCaptioner is also affordable, meaning that even organizations with a small budget can still make their content accessible. 

Transcriptions for Radio


Radio stations are constantly interviewing guests and recording conversations that they need to take quotes out of for social media content or future reference. Transcribing content from a radio or podcast is fast and easy with SubCaptioner and provides an accurate text transcript to be used in multiple ways. These transcripts can even be uploaded online alongside a radio recording or podcast episode to boost SEO rankings on search engines. 

Transcriptions for Government


Government organizations have the responsibility of sharing important information with the public in a manner that is easily accessible to everyone. That means that this content needs to be accessible to those who are hard of hearing, who speak a foreign language, or who watch recordings with the sound off. Transcriptions and closed captions are an easy way to make government content accessible. They also provide a simple way of keeping a record of important information for future reference.

Why you should transcribe your content

Adding transcription and closed caption files to the audio or video content you post online can improve your content’s accessibility, usability, SEO performance, engagement rates, and shareability.


69% of people watch videos online with the sound off. Without closed captions or a text transcript, content isn’t accessible to them. Untranscribed content also is inaccessible to individuals who are deaf or experience hearing loss.


Consider, also, the benefits of having a written text version of your video or audio file. This text file can be used to easily pull quotes and create other content for social media as well as store information for future reference and use.

SEO Performance

Transcriptions are full of keywords that make it easier for search engines, such as Google, to crawl and index your content. Better indexing leads to more search traffic and viewers.

Engagement Rates

Videos that are captioned get 40% more views and often experience a longer average watch time. When viewers watch the video the whole way through, they’re more likely to interact by liking, commenting, or sharing. Transcripts also improve engagement on podcasts, by giving viewers a place to click on links or share quotes.


It can be difficult for viewers, especially viewers who are also reporters, to share direct quotes from your content if it isn’t transcribed. Providing a transcript of your content gives individuals the chance to copy and paste portions of what was said and share it with their own personal communities.

Many video players (such as VLC) allow you to preview your video with captions from an SRT file such as that created by SubCaptioner. If you spot an error then the SRT file can be easily modified in any text editor. For more advanced editing and/or longer media files, we recommend a caption/subtitle editing software such as WinCaps.
