Problem
Content creators and enterprises often struggle to generate accurate transcripts and synchronized captions for large volumes of audio and video assets. Manual transcription is labor-intensive, costly, and prone to errors, while automated tools frequently lack the precision required for compliance with accessibility regulations. Delays in captioning can impede audience reach and expose organizations to legal risk.
Solution
cielo24 offers a hybrid transcription platform that combines AI-driven speech recognition with optional human review to deliver high‑accuracy text and timed captions. Users upload media in any common format, and the system automatically generates a draft transcript, which can be refined by professional linguists for industry‑standard precision. The resulting captions are synchronized to the original timeline and exported in multiple subtitle formats (SRT, VTT, TTML) for seamless integration into publishing workflows. An API and SDK enable developers to embed transcription and captioning directly into content management systems, streaming services, or e‑learning platforms. All data is processed in a secure, HIPAA‑compliant cloud environment, supporting batch jobs and rapid turnaround options to meet tight publishing schedules.
Target Audience
Primary customers are media production companies, broadcasters, and enterprise teams that need scalable transcription and captioning for video, podcast, and e‑learning content, as well as SaaS platforms seeking to embed accessibility features into their services.
