 STAGES  Generate automatic captions for videos or sound objects with speech or vocals and make speech visible in text form. This allows subtitles to be displayed directly in the video and customized. Creating karaoke videos or adding images to podcasts are other possible use cases.

The automatic transcription is created with the help of artificial intelligence (AI). Your audio data is transcoded on your device. Depending on the size of the language model, this requires large amounts of RAM (approx. 7 GB) and a lot of computing power.

When you start the AI-supported transcription for the first time, the necessary software is downloaded once (online connection required) and saved on your computer (approx. 1.46 GB). It is then permanently available in the program.

In the next step, you can select the language model and thus influence the accuracy and speed with which the text is to be analyzed.

The calculation can be carried out in the CPU or - if technically possible - by the graphics card. How long the transcription takes depends not only on the selected model settings but also on the performance of your hardware and the volume of text to be transcribed.
 
Specify the language of the speech or vocals in your video or sound file. This can increase the accuracy of the transcription.

Segmentation is used to define how many timing marks are generated. When segmenting words, each word receives a timing mark. If you select Paragraphs, you will receive the text with a separation into longer phrases. Words and paragraphs identifies paragraphs, which in turn are segmented word by word.
