Audio Transcription

I worked on the Babel Audio platform for audio transcription tasks, where I converted spoken audio into accurate text using speech-to-text methods. I handled different types of audio, including conversations and recordings with background noise, and ensured clear and correct transcription. I also performed basic data labeling tasks such as correcting words, adding proper punctuation, and cleaning up transcripts. Throughout the project, I followed all provided guidelines carefully to maintain high-quality and consistent output. I successfully completed a large number of audio files within deadlines while maintaining accuracy and attention to detail.
