...Unfortunately, YouTube's transcriptions are notoriously riddled with mistakes. So, either transcribe your own video files or hire a transcription service such as Speechpad (which charges $1 per minute of audio or video content) to create the files for you. Your transcription file can then be uploaded to the "Caption" section of your video pages, providing both YouTube and Google with more accurate information for indexing and ranking your videos.
So, transcripts sound great, right? But who has time to transcribe your podcasts and videos? I know I don’t! There is a great tool that can transcribe your videos and podcasts for you at very reasonable rates–best of all, the transcripts have been extremely accurate. Check out Speechpad, a service that utilizes a process involving both automated transcription and human QA to provide transcripts for your rich media in a very timely fashion. Pricing is based on turnaround time and can be as inexpensive as $1/minute in file length. $8 to transcribe that 8 minute audio file? Pretty great!
