Transcription differs from standard speech recognition. Instead of sitting in front of your computer and dictating with an application open, you dictate into a portable digital recorder or an iPhone. Nuance’s free Dragon Recorder iOS app lets you make voice recordings on an iPhone, and many companies sell portable digital recorders.
Dragon Dictate is a speaker-dependent program, meaning that you start by creating a voice profile and Dragon Dictate interprets the sounds it hears based on this profile. For this reason, you can’t use Dragon Dictate’s transcription feature for meetings or interviews. (Nuance says that it plans to update its MacSpeech Scribe transcription program, which doesn’t run on OS X 10.7 or 10.8, but which can transcribe audio without requiring an existing profile. The company did not say when it expects to release the updated program.)
How to dictate for transcription
You don’t have to pay attention to how your words will look on your computer screen when recording your voice for transcription, but you still need to think about it and use the special words that tell Dragon Dictate when to insert punctuation, when to skip lines, when to capitalize words, and more. You need to speak like this:
Today comma I had a meeting with John comma Susan and Charlie about the caps on open house caps off comma and we agreed that we would plan to hold it on January 7 period
Once you get used to working with Dragon Dictate, these special words will become second nature; but if you don’t use them when you dictate into a portable recorder, the transcribed text will appear as one long run-on paragraph.
As I said earlier, you can use Nuance’s Dragon Recorder iOS app on an iPhone, or you can use a portable digital recorder. I tested the transcription feature using a Philips Voice Tracer—a small, lightweight handheld digital recorder.
If you’re using the Dragon Recorder iOS app, transfer files by connecting your iPhone to your Mac, going to iTunes, clicking on the iPhone in the iTunes source list,and then clicking the Apps tab. Look for Dragon Recorder in the list of apps in the File Sharing section, then click on it. You’ll see files listed in the pane to the right. Click the file that you want to copy to your Mac, and then click Save To and save the file. (Dragon Recorder also offers Wi-Fi sharing, but working via Wi-Fi can be slow if you have big files to transfer.)
If you’re using a portable digital recorder, connect it to your Mac with its USB cable, click its icon in the Finder’s sidebar, and then look in the folders that you see. The Voice Tracer’s Voice folder contains four subfolders. Look inside those folders to find your voice files, and copy the files to your Mac.
Transcribing with Dragon Dictate
Launch Dragon Dictate, choose Tools > Transcription, locate your file, and click Open. The first time Dragon Dictate performs a transcription, it will display a small window that analyzes 20 seconds of your speech. If you see any mistakes, click the displayed text and correct the errors. This will help Dragon Dictate transcribe your speech more efficiently.
Once you’ve completed the speech check, Dragon Dictate will transcribe your speech file. This may take a fair amount of time, depending on how much content you dictated; but you’ll be able to see the progress on screen, because Dragon Dictate displays the text as it interprets it. Unlike “live” dictation with Dragon Dictate, corrections that you make to the transcribed text won’t affect your voice profile.
Dragon Dictate is not designed to learn from files that it has transcribed. You’ll notice that the program’s accuracy is a bit lower than when you’re working at your desk. This is, in part, because of the way transcription works, but also because most of the texts you transcribe will be recordings made on the go. Some people use transcription to take notes during the day (in the car, in a plane, in a waiting room) and because the audio conditions you’re recording under may be far from ideal. The iPhone 5’s microphone is much improved over previous models, and many digital voice recorders offer some active noise reduction, but the sound quality will always be at least a little worse than you’d get in a quiet office.
If you’re performing dictation with an iOS device, make sure that you have enough free storage space to handle the job. Dragon Recorder saves audio files in .wav format, and these files take up about 2.7MB per minute. If you prefer to use a digital recorder, you should be aware that, though Dragon Dictate 3 can recognize a number of audio file formats (.mov, .wav, .aiff, .m4v, and .m4a), it does not support .mp3 files.
Unfortunately, many digital recorders—such as the Philips Voice Tracer that I used in my tests—support only .wav and .mp3 files, which means that you’ll need to use the uncompressed .wav format that takes up the most space. Some recorders support only .wma and .mp3 and you can’t bring the audio file directly into Dragon Dictate 3. Most people won’t run out of space on their digital recorder, but if you do a lot of dictation, keep this limit in mind and consider get a recorder with more room. (The standard 2GB digital recorder holds about 3 hours of recording in .wav format.)
As noted earlier, you can’t transcribe interviews directly, but you can obtain a transcript of an interview by a method sometimes called parrot speaking; it involves listening to a recording of an interview on headphones and repeating into a recording device everything that the interviewer and the interviewee say. Since Dragon Dictate can transcribe your voice, but not the voice of the people in the interview, you can feed the parroted file into the program. To some extent, this arrangement resembles simultaneous interpretation, where an interpreter hears someone speak in one language and then, in turn, provides an oral translation in another language. Here, you won’t be switching languages, but a similar mental process is involved: You hear something, and then you speak it.
Once you get hooked on dictation, you’ll look for ways to use it as much as possible. Transcription is one way to use dictation even when you’re not in front of your computer. As long as you have good hardware, know how to dictate, and are willing to accept the limitations of the technology, it can save you a lot of time.
