Find out all about data transcription and how machine learning is making it easier.

What is data transcription?

It is the act of  converting speech from audio or video files to  text for documentation or qualitative analysis.It gives room for the transcriber to put himself  within the context of the speech

Types of data transcription

Verbatim transcription 

It is the method of transcription which records every aspect of the speech as it sounded.  Whether there is a pause, a stutter, a slang or an interjection, everything is recorded. It requires no effort to cover up errors or repetitions.

Edited transcription 

With this method, the verbatim speech is formalized and  edited in a clarified and concise manner. It takes certain things including grammatical errors, incomplete sentences and slang into account.

Intelligent transcription

It  is the thoroughly cleaned-up version of the verbatim speech. The non-functional words, sounds and expressions are removed. Grammatical errors are taken into consideration. To convey the exact intended meaning,paraphrasing may come in. 

How is data transcription used in Machine Learning projects?

Machine learning makes use of voice and speech recognition software which converts the files to text format. 

In the medical field

The medical history of patients is recorded but is a time-consuming process for medical professionals. Doctors dictate among others, the summary of consultations, patient reports, and surgical procedures. The audio files are converted to text using speech-to-text softwares .

Broadcasting and Entertainment  Industry

The text-to -speech software is used to transcribe musical lyrics. In addition, it is used for movie subtitles. News channels also transcribe dialogues that come up during interviews or documentaries for future-proof or clarity. 

Legal Transcription

For the sake of evidence, disambiguation and future litigation which may drag for years, transcription is used .It also helps legal officers who are unable to keep up with the speed of proceedings at the court 

Benefits of data transcription

Accuracy with Speed

Manual transcriptions are very time consuming and tiring. Artificial Intelligence makes use of Natural Language Processing to transcribe data in minutes. It is very useful in situations where the voice data is very voluminous.

Timestamping

The machine learning  softwares used for transcription has the ability to detect chronological order of events and the various speakers. It allows users to identify vital portions of lengthy audio files and create soundbites.

Integration

Companies can integrate their software programs with machine learning models to automatically send transcription data to their  project management and customer relations  tools.
