Adobe Premiere Pro can analyze spoken words and generate text metadata. You can edit and search text metadata like any other metadata properties. You can then navigate to the times at which specific words are spoken, to better align edits, advertising, and subtitles.
The speech analysis feature can use any of several language-specific and dialect-specific libraries, such as libraries for Spanish and UK English.
To download more language-specific and dialect-specific libraries, see this link on the Adobe website.
In Premiere Pro, the Speech Analysis feature is also available for clips when there is at least one component audio clip in the merged clip. Users can choose to analyze all audio tracks in a merged clip, or a single one.
