The CastingWords API allows you to put their 100% human transcription service into your company's workflow. The API's technical webpage describes the API as "RESTish," with responses returned in a variety of formats. The site states that, "The goal is not to follow REST's practices closely, but rather to make an easy API to get up to speed with using a dynamic language or CURL. It accepts data as URL encoded key value pairs. An HTTP body of type JSON in a POST request and with content type application/json is also accepted."
Access to the API requires an API Key and an account.
CastingWords uses Amazon's Mechanical Turk to get the transcription done. MTurk farms out HITs--Human Intelligence Tasks including transcription--to people working from their computers. In an interview with Amazon, CastingWords co-founder Nathan McFarland noted that MTurk's "quality is astounding."
Oversight of the quality is also done by MTurk--by other MTurk workers checking the transcription. As McFarland continues, "Amazon Mechanical Turk is the core of our business. We are in a people-hungry business. All of our work is done by people. It’s not a mass-production thing; it is individual hand-crafted work."
CastingWorks guarantees its deadlines for high quality submissions. Transcriptions are delivered back to the customer in plain text, HTML and RTF formats.
