1. Don't bother with voice recognition software. You will have to have someone proofread and edit your transcript heavily afterwards anyway. Get an affordable speedy transcriptionist instead right from the start. You'll save money in the long run.
2. Make sure your audio is clear, free of static and background noise, and that the person(s) speaking is being as articulate as possible. Using a good quality microphone is key. Also testing your audio equipment in the same environment in which you will be using it first will save you a lot of headaches later.
3. Remember who your target audience is and stay on topic. Try to remember that you are being recorded and omit the types of verbal trackbacks that you use when talking casually. Write things down if it helps.
4. Don't record more than 30 minutes at a time--it will be too cumbersome a document to read otherwise, unless you plan to create several chapters in an e-book or it is part of a larger body of work.
5. If your audio/video is a webinar or teleseminar, make sure you clearly identify each caller and spell their names for your transcriptionist ahead of time.
6. Find a transcriptionist with whom you can relate to well personally and who is willing to transcribe your transcripts just the way you like them done. There are disagreeable and agreeable transcriptionists. Shoot for the latter!
7. Make sure your transcription service is US-based (no outsourcing--it's just not worth the potential savings), affordable, quick, and uses English accurately.
I will expand upon each of these seven tips individually in my next article.
