Yes. When you start recording the voice-over, any other audio tracks on the Timeline 
will be heard as you record.

The easiest way to create a submix track is to assign those three tracks to that submix 
track and apply the effect to the submix.

Adobe Premiere Pro CS5 can convert an audio fi le 
containing speech to a text transcription fi le. Then 
you can search the audio fi le for keywords, mark 
the In and Out points of your clips, and even locate 
a specifi c video frame using a text search tool. New 
is the ability to detect faces in your clips so you can 
more quickly fi nd clips with faces in the Project panel.

LESSON 14
Analyzing Content
Getting started
Although it may not be obvious from the small sample files used in this lesson, 
speech transcription can be a huge time-saver, allowing you to do text searches to 
find precisely the video frame in which a specific word is spoken. You can easily 
add markers or edit points after using this feature to locate keywords. Without this 
feature, you would need to scrub or play the audio of the file to listen for keywords.
You’ll notice that it takes some time for Adobe Premiere Pro CS5 to transcribe an 
audio file to text. But this process can run in batch mode in the background while 
you do other work. It’s also worth noting that once the transcription occurs, the 
transcribed text becomes part of the audio file’s metadata. Even if you export the 
file, the transcription will remain with the file.
