Editor's Notes
Express Scribe is not a captioning tool, per se, but it is a tool to make transcription easier. You can control the speed of the playback without distortion. You can control the playback with keystrokes within the software or with a foot pedal.
Express Scribe has a voice recognition feature, where it will make an attempt at automatically recognizing the speech. In my experience, it’s pretty bad. But depending on the quality of the audio, it might be worth running through the automatic recognition and then going back to edit. But personally, I think it takes more time to fix the transcript than to type it all from scratch. But it’s up to you.
It is available on both Windows and iOS, and there is a free version as well as a paid version with expanded functioning. The main difference between the free and paid version is that the free version only plays audio, while the paid version will also play video. There are some brands of foot pedals that will also only work with the paid version. The price for the paid version is listed as $40, but is frequently on sale for $19.99.
Transcribe is similar to Express Scribe, but is browser-based, although it can be used offline as well. The benefit of a web-based tool is that you can access it from any computer. Like Express Scribe, Transcribe also allows you to have variable-speed playback without distortion and to control the playback with keystrokes or foot pedal. One feature that Express Scribe does NOT have that Transcribe does is the ability to add time codes into the transcript.
Transcribe also has voice recognition, but it doesn’t try to understand the file. It is meant for “shadowing” – the user repeating everything that is said in the audio, and it works surprisingly well. It’s still not perfect, but can dramatically reduce the time required for transcribing by capturing the majority of the text, which then needs to be cleaned up. It works better than voice recognition in general because (ideally) there is one speaker, in a controlled space, with good enunciation.
Transcribe has a price of $20/year.
Inqscribe has most of the same features as the other tools – variable playback of audio and video, use of keystrokes or footpedal to control playback. It does not have the voice recognition feature that Transcribe has, but it does have the ability to add timecodes like Transcribe. It also has the additional feature of exporting captioned videos into QuickTime once it has been transcribed and time coded in Inqscribe. The full price for Inqscribe is $99, but there is an educational price of $69 and a student price of $39.
Unfortunately, there is not one captioning format that will work with all video players. For example, if a video is played in QuickTime, it needs a different caption file than if it will be played in iTunes, or Windows Media Player. HTML5 will eventually solve some of these issues, but it’s not ready yet. So in the meantime, you have to consider how your video will be played when creating the caption file.
YouTube starting offering captions a while ago, and it was pretty awful! But the ability to add captions to YouTube videos has greatly improved. As long as you don’t use the voice recognition tool! You can upload a timed caption file that you’ve created in another tool, copy a transcript (or type it into YouTube while you’re watching the video) and have it automatically time sync, or you can copy or type the transcript and manually time sync. The automatic time sync isn’t too bad, but it doesn’t know where to break lines appropriately, how many words to put on the screen, etc. Fortunately, if you decide to use any of the automated tools, you can go back and edit.
