Transcribing
Videos
If you do not have a
script of the video, you can get the script in many ways, such as:
- With a digital
video, you can use a foot pedal control like vPedal
to transcribe the video. It costs less than $100.
- Train a speech
recognition software such as ViaVoice
(Win) or MacSpeech (Mac) for
a few hours. Then listen to the videotape and repeat the dialogue
into the microphone. At the beginning, you are going to get lot of
errors. But you can teach the software to fix the errors and down
the road you can expect to get about 95% accuracy.
- Use a professional
transcription service. This is the most expensive way to generate
the script.
There is a
simple way to transcribe and input the spoken dialog directly to your
computer. All you need to do is spend an hour or two training a speech
recognition software to recognize your speech. By using Naturally
Speaking (English and Spanish) and ViaVoice
(English) speech recognition
software you can transcribe a
video.
With the Naturally
Speaking or ViaVoice software, you can listen to the video, and repeat
the words that are being said into the microphone. If you want to use
this transcription for post captioning, you can import the document into
the CPC Captioning software and the text will automatically be broken up
into formatted captions.
Lanuguage
Supported
Naturally Speaking is available in multiple languages such as, English,
Spanish, French, German. ViaVoice is available only in English
Accuracy
After training these speech recognition software for an hour or two, you
can get an accuracy of about 85%. If you fixes the errors and let the
software know about the errors, the software will not make the mistakes
again. Eventually you can easily get an accuracy of 95% or so.
Naturally
Speaking software analyzes a complete sentence or a phrase until you
pause talking and gives better accuracy compared to ViaVoice. Since
Naturally Speaking analyzes the text before showing it on the screen, if
you use it for live captioning, the captions will be delayed by a few
seconds. For transcription purposes, the delay does not matter. So
Naturally speaking is better than ViaVoice from the accuracy point of
view.
