What is Audio Transcription ?

Audio transcription is the process of taking audio data and turning it into written text. This could be done for any number of reasons; but at MarsCrowd, it’s all about how that data can be utilized for training AI models to do this process automatically. Automated Speech Recognition is a major component of Conversational AI, and the most advanced models depend on large amounts of data being transcribed and labeled accurately.

Audio Transcription in Action

When we work together on a project, you can expect a seamless process for delivery. Audio transcription can be broken down into 5 general steps from the raw upload of data to our in-house platform to the final delivery back to the end client. The overall goal is to accurately take an audio file and turn it into a text file for better accessibility. The process looks something like the model below:

How does Audio Transcription work?

The first step in audio transcription is the collection of audio data into a usable dataset. Our Crowd then takes this data and manually converts it into text. By maintianing proper classifiers and accurate labeling, this manual transcribing can be turned into an automated process. When conversational AI incorporates spoken inputs, this process must happen in order for an appropriate response.
In the end, the model you train and feed data must be diverse and complete in order to work in multiple contexts. A global Crowd with experts in 120+ languages is ready to provide the well-roundedness you need for your solutions. The question is: are you ready?
