About

An A.I. speech-to-text transcription service

Datumo provides high quality data for smarter AI. As part of Datumo's Data Sponsorship Program, Datumo cooperated with ActionPower in building the following dataset.

ActionPower aspires to unlock the potential of A.I.. Many have introduced A.I. and its potential, but not many have delivered an A.I. model in practical use. ActionPower aims to deliver a life-changing A.I. model with their research on technology and services.

Under the belief of “Action brings power”, ActionPower is an AI-based startup company that offers speech recognition and natural language processing technology services. Speech recognition requires a variety of high-tech subtechnology. ActionPower is the first in Korea to release an A.I. speech-to-text transcription service, Daglo. The startup has developed it’s own speech recognition technology and aims to release more services to enhance people’s lives using Daglo, the best service for Korean speech recognition in the world.

Daglo is the fist A.I. model of ActionPower. People record audio files from lectures, phone calls, meetings, and so on, but it is inconvenient to check the recordings because searching keywords in audio files is impossible and it takes as much time to listen as to record. However, upon speech-to-text transcription, most of the recording can be easily documented. Daglo is an A.I. based web service for automated speech-to-text transcription. It also offers editing features for the transcribed text and replays the audio file when the user clicks on a specific part of text. Number of users in Daglo is continuously growing and companies including Samsung C&T, TWC, and the local government are some of the users.

Testimonial

“We were able to build datasets that enhance the accuracy of speech recognition. Within a short amount time, much data were collected and pre-processed in the appropriate format for A.I. training. We will do our best to use the datasets to develop a speech recognition service that can better people’s lives.”
