ASR AUTOMATIC SPEECH RECOGNITION 2019


Speech recognition software works by breaking down the audio of a speech recording into individual sounds, analyzing each sound, using algorithms to find the most probable word fit in that language, and transcribing those sounds into text.

algorithms used in this form of technology include PLP features, Viterbi search, deep neural networks, discrimination training, WFST framework
