Acoustic Unit Discovery

"Acoustic Unit Discovery" refers to the automatic identification and extraction of basic acoustic units, such as phonemes or sub-phonemes, from speech signals through unsupervised learning methods in speech signal processing. Its goal is to construct an acoustic model that can accurately represent speech signals, thereby improving the performance of speech recognition, synthesis, and analysis. This technology has significant application value in areas like speech coding, speech synthesis, and speech recognition, effectively enhancing the robustness and adaptability of systems.
