A tool that can help you manually align text to audio, adjust existing alignments, edit transcripts, etc. in your process of creating a speech dataset.
Get the code, and open it with any modern browser.
To begin, load an audio file and a TXT or JSON file.
If you use TXT, split your text into lines.
For a JSON file, it should be like the following:
[{"Start": Starting time of this line in millisecond,
"Stop": Ending time of this line in millisecond,
"Text":The text of this line},
...]After loading, play the audio for a few seconds so that the regions on the wave are placed at the correct positions.
After editing, click Save can save your edit into a JSON in the above format.
There are some keyboard shortcuts to help you do your work easilier.
ENTER: Play/Pause the audio.
SPACE: Play audio of the current line.
UP: Go to previous line.
DOWN: Go to next line.
LEFT / RIGHT: Move the player cursor backward/forward.
CTRL + LEFT / RIGHT: Skip to the previous/next region boundary.
F: Set Start. D: Shift Start 10ms later. S: Shift Start 10ms earlier.
J: Set End. K: Shift End 10ms earlier. L: Shift End 10ms later.
If you need help about the keyboard shortcuts when editing, simply click the blue icon next to the title.
