O2I Developed API to Automate Transcription of Audio Files for a Hong Kong Startup

Case Study on API Development to Automate Transcription of Audio Files

The Client

The customer is a Hong Kong-based startup that serves customers across the world primarily as a business growth consultancy, but also provides other ancillary services.

Client's Requirement

The client wanted our help in the transcription project as they were overwhelmed by the transcription needs. They wanted us to overcome limitations and complete transcriptions with agility and accuracy.

Business Challenges

This particular issue was regarding a transcription project. The customer receives audio files that need to be converted into text for transcribing. The audio files are uploaded onto the server one by one and converted into text. The process was time-consuming, and there was no quality check being performed. This was an inefficient method of working, and they wanted to streamline the process.

Our Solution

Our experts at Outsource2india brainstormed to decide the best way to resolve the customer's pain point. After hours of discussing with the customer and within the team, we came up with the ideal solution. Earlier it was a wholly automated process, but our team decided to have a QA team manually check for errors and quality of the transcription.

They got the audio file as well as the transcribed text on a screen which the team checked. We created an API interface and the files are transcribed in batches. By implementing moderations and permissions, we ensured security - only authorized personnel could now have access to files.

The Result

The whole process was more streamlined, as audio files were streamed from the Amazon server. The files were transcribed in batches, and each file was checked by the QA team. So now the transcribed files are lined up for quality check in a batch process. The final solution consisted of one module that was automated and a manual module for QA check. There was increased efficiency, speed, and quality in the transcribed files, and the customer was very happy with the result.
