So while it may seem post-editing requires extra work, combining ASR and manual post-editing (”expert in the loop” workflow) still saves you 60%-80% of the time compared to conventional transcription.īut the most important characteristic of AI transcription is the fact that each word has a time-code. ![]() Given a WER of 1%-2%, the pos-editing time of an automated transcript, is rough twice the length of the clip, which is still 3 to 4 times faster compared to conventional transcription. ![]() Limecraft offers customised ASR solutions with a WER that is significantly lower compared to the standard solutions offered by Microsoft Videoindexer, Google Speech or Amazon Recognition. Hence sometimes it is better to optimise for accuracy rather than for the lowest price per hour, and you may want to look for a complete solution that includes a proper editor for reviewing and correcting the automatically created transcript. While a small WER might be acceptable for indexing purposes, it may be prohibitive when the results are intended for publication. Depending on the audio quality and the ASR engine type, expect a WER of 2%-20%, compared to completely accurate by manual transcription. The quality of automated transcription is often expressed in word error rate (WER). That boils down to at least 24 times difference in turn-around time. AI transcription as offered by Limecraft runs 4 times faster than real-time, whereas manual transcription typically takes 6 to 8 times the length of the clip.

This is called the “Expert in the loop” workflow. ![]() For professional use, it is important to make the results of automated transcription editable in an interface that highlights confidence scores, and that allows the user to modify words, speakers of timing. Good AI transcription services include accurate speaker segmentation (sometimes referred to as “diarisation”), proper interpunction including exclamation and question marks. Training involves learning language models by processing millions of web pages, and learning acoustic models by listening to labelled data sets of real human speech. The keys to successfully integrate AI transcription as part of your workspaceĪI transcription is a method of automatically turning spoken words into timed text using artificial intelligence that has been trained to do so.Improve collaboration and allow repurposing of content.The use cases for AI transcription in video.Why good audio transcripts are important for you as a video producer.The key differences between manual and AI transcription.Not familiar with Limecraft yet? Feel free to sign up for a free trial, or request a personalised demo. In this post, we will discuss the main differences between conventional and AI transcription, explain why it is important to optimise for high-quality results, break down the main use cases, and describe in great detail how to successfully deploy AI transcription as part of your workspace. AI transcription is faster, more accurate, it drastically improves the visibility of your content, and thus it eases collaboration within global video production teams. When asked for feedback, journalists and archive producers who have successfully adopted AI transcription at the core of their workspace, never turn back to manual transcription. Compared to last year, Limecraft customers are processing 448% more material using AI transcription services. ![]()
