HMM Toolkit

The HMM Toolkit (HTK) is a software library used for developing systems that recognize patterns, such as speech. It employs Hidden Markov Models (HMMs), mathematical models that represent sequences with probabilistic states. HTK helps in training these models on speech data, enabling applications like speech recognition, speaker identification, or language processing. Essentially, it provides tools to analyze, train, and evaluate sequential data, allowing computers to interpret complex patterns in speech signals or other time-based data accurately.
