Automatic Transcription services
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.
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.
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.

Language training uses a wide variety of accents and dialects to provide global language models rather than regional specific variants. A conversation in English between American, Australian, British, and Indian speakers, for instance, can therefore be handled by a single language model.
There is also a bilingual Spanish & English model for mixed language content (note that this is a two language transcription model and does not provide translation). Automatic speech-to-text translation is available to/from English and a selection of over 30 of the above languages (marked *).
We offer automated subtitle translations between English and over 30 different languages. Visit our “Automatic Subtitle Translator” or “Automatic Live Captions and Subtitles” pages to learn more about there services and prices.

Live captions & subtitles are presented differently to the file-based equivalent. Text is presented word-by-word rather than as a complete block, with rows scrolling upwards as new text appears, we recommend using a limit of 3 rows to ensure that text is always readable. Text clears automatically when there is a significant pause in speech.
Live captions are typically 2-5 seconds behind the audio, a longer delay tends to mean more accuracy, better punctuation and better speaker detection. We recommend using the shortest “max delay” value that provides acceptable accuracy for your content.
The “Wait for accuracy” mode delivers the most accurate results as a complete phrase (in no longer than the Max Delay value). “Fast with updates” provides initial text results typically in less than a second but that text may be subject to visible changes as the ASR refines its recognition of the complete phrase based on later context (within the timescale of the Max Delay value).
