Advances in Artificial Intelligence and Machine learning have enabled a variety of new technologies. One such technology is Automatic Speech Recognition (ASR), where a machine is given audio and transcribes the words that were spoken. ASR can be applied in a variety of domains to improve general usability and safety. One such domain is Air Traffic Control (ATC). ASR in ATC promises to improve safety in a mission critical environment. ASR models have historically required a large amount of clean training data. ATC environments are noisy and acquiring labeled data is a difficult, expertise dependent task. This thesis attempts to solve these problems by presenting a machine learning framework which uses word-by-word audio samples to transcribe ATC speech. Instead of transcribing an entire speech sample, this framework transcribes every word individually. Then, overall transcription is pieced together based on the word sequence. Each stage of the framework is trained and tested independently of one another, and the overall performance is gauged. The overall framework was gauged to be a feasible approach to ASR in ATC.
