Limecraft offers embedded AI transcription services that can be used for text-based editing and subtitling


Speech-to-Text Transcription

Using Limecraft, you have access built-in speech to text or automatic speech recognition services to automatically convert audio into timed text with over 99% accuracy. The result are in an editable form, allowing you to review the automatically generated transcription before using it.

Depending on the quality of the audio, Limecraft's automated subtitling services save up to 80% of the time.

Limecraft Flow turns audio into well formed captions or subtitles



Upon speech recognition or import of a pre-existing transcript, Limecraft takes care of the spotting. We take into account the rhythm of the edit, desired reading speed, pauses in the audio, etc. By using Natural Language Processing (NLP), subtitles are optimised for maximum readability. When finished, you can use the editor to further optimise the result.

Using the initial subtitle template, you can add more languages in the blink of an eye. To do so, we take the text from the subtitles to recreate a script, which is then used for machine translation. The result of the translation is redistributed in the original timing template while choosing the most logical places to use line breaks.

Limecraft Flow seamlessly integrates 3rd party applications like facebook, adobe premiere, youtube, vimeo, and Avid Media Composer



When finished, you can export your subtitles in a wide range of available formats. Now also including the option to export video with burned-in Subtitles.
