SpeechPad is a transcription service where you can upload any audio or video file and they will get it converted to text. You may also point to media files that are online – like a YouTube video or an MP3 file – and they’ll deliver the transcriptions as a Word document or an HTML file for posting on your website.
If you are a video producer, you may want to attach transcripts with your videos to improve visibility in search engines (SEO).
SpeechPad charges $1 per minute of audio and the transcription is delivered within a week.
SpeakerText.com is a good alternative to SpeechPad – they charge $2/minute of audio but here you need to buy credits for at least 60 minutes.
