Beszédfelismerési

Beszédfelismerési refers to the process and technology that enables a computer system to understand human speech. Also known as automatic speech recognition (ASR), it is a multidisciplinary field that combines linguistics, computer science, and electrical engineering. The primary goal of beszédfelismerési is to convert spoken words into a text format that a computer can process and interpret.

The process typically involves several stages. First, acoustic modeling analyzes the sounds of speech, breaking them down into smaller units called phonemes. This is often followed by language modeling, which uses statistical probabilities to predict the likelihood of word sequences. Decoders then combine these models to determine the most probable sequence of words corresponding to the spoken input.

Beszédfelismerési systems have evolved significantly over the years, moving from early, limited systems to sophisticated applications used in everyday technology. Applications are widespread and include voice assistants like Siri and Alexa, dictation software, customer service chatbots, and systems for transcribing meetings or lectures. Ongoing research aims to improve accuracy, handle diverse accents and dialects, and adapt to noisy environments. The development of machine learning and deep learning techniques has been particularly instrumental in recent advancements in beszédfelismerési.
