Khmer Automatic Speech Recognition (Khmer ASR) is an application that uses Artificial Intelligence technology to automatically convert speech and audio files in Khmer into written text. This application was entirely developed by a team of young researchers from Cambodia Academy of Digital Technology (formerly known as National Institute of Posts, Telecommunications, and ICT) of the Ministry of Posts and Telecommunications, using a combination of Statistical Learning and Deep Learning methods, which are the new automation approaches for converting speech into written text for complex script languages ​​with less digital data.
