Introduction This project is about improving the word error rate in audio transcription by KALDI. KALDI is used to transcript audio using various language and acoustic models. The previous work in improving the word error rate is done by improving the language and acoustic models of audio. our project focus on improving the input signal quality by audio processing using the software HARK. HARK works on Missing feature theory and eliminates noise by various algorithms.

Background Speech transcription is a process done by computer hardware and software to transform an audio input into a text output. Speech transcription increases the accessibility and understand-ability of voice recordings and other audio materials for many different use cases.
