Looking for a professional to transcribe audio of short (15 minutes or less) conversations between Spanish speakers. No translation to English is necessary. Looking for someone who can do at least four transcriptions a month (for a total of approximately 60 minutes of audio). When you bid on this project, please state clearly what you charge is per 60 minutes of audio. Transcripts are to be delivered in a standard Microsoft Word document.
