Speech to text¶
New in version 21.04.0.
Speech to text doesn’t work with version 21.04.2 due to Vosk API issues. Use version 21.04.1 or 21.04.3 and later versions.
Python 3 needs to be installed on your computer as well as the vosk and srt python modules:
On most Linux distributions python is installed by default. You can check if that is the case for you too by running
python3 -V in a terminal. If python is missing just search the internet, there are lots of instructions around.
To install vosk and srt open a terminal and run:
pip3 install vosk srt
Install a language¶
Click on the link to get a language model.
Drag & drop the language you want from the vosk-model download page to the model window, and it will download and extract it for you.
If you have problems press on the Check configuration button.
Creating subtitle by speech recognition¶
Mark the timeline zone you want to recognize (adjust the blue line).
Click on the Speech recognition icon.
Choose the language.
Choose how the selected zone should be applied.
Press on the Process button.
The subtitle gets created and inserted automatically.
Remark: Only timeline zone is implemented for now in automatic subtitles.
Remark to 4: The default is to analyze only the timeline zone (all tracks) (the blue bar in the timeline ruler). Set the zone in the timeline to what you want to analyze (use I and O to set in and out points). Selected clips option analyses the selected clip only.
Creating clips by speech recognition¶
This is useful for interviews and other speech-related footage. Enable themenu item.
Select a clip in the project bin.
If needed set in/out point in the clip monitor and enable Selected zone only selection box. This will only recognize the text inside the zone.
Choose the correct language.
Press the Start Recognition button.
Selecting the text you want to either.
Put into the timeline.
Save edited text as a new playlist.
Add a Bookmark. You can jump to these bookmarks in the timeline with the Alt + arrow shortcut or edit the bookmark by double click.
Delete the selection.
Here you can search in the text.
And navigate up or down in the text.
Open the clip in the clip monitor and open the speech editor window () .
Select your language or Install a language and download the model for it.
Then click Start Recognition button.
Once this is done, click on the time-code where no-speech is indicated and just hit the delete key. Repeat the operation for all the parts you want to remove, including where someone says what you don’t want to listen in your final edit.
Once finished, make sure Selected zone only is disabled, click on the Save button on the lower left part of the speech editor window and after few seconds a new playlist is added in the project bin without silence and without the text you don’t want.
