Preprocessing of audio data for voice transcription systems
(КПІ ім. Ігоря Сікорського, 2023) Drahan, M.; Pysarenko, A.
Voice messages are currently a powerful data collection tool. The aim of the study is to speed up the transcription of audio files. To achieve the goal, it is suggested to use a bandpass filter with a lower passband frequency in the range of 150-200 Hz and an upper passband frequency in the range of 3500-7000 Hz. The success of the system is based on the selection of the filter that optimally speeds up the transcription of audio files.
