How Automatic Speech Recognition (ASR) works?

Automatic Speech Recognition, or ASR for short, is a technique that allows humans to use their voices to communicate with a computer interface that resembles regular human speech in its most advanced forms.

Numerous automatic speech recognition software and devices are available, but the more advanced options rely on artificial intelligence and machine learning. To interpret and analyze human speech, they combine grammar, syntax, structure, and composition of audio and voice signals.

Speech recognizers consist of the speech input, feature extraction, feature vectors, a decoder, and a word output. The decoder employs acoustic models, a pronunciation dictionary, and language models To identify the right output.

The software constructs hypotheses about what the user is saying based on programming and voice patterns. After estimating what the users most likely said, the software transcribes the discussion into the text.

Automatic Speech recognition software uses natural language processing (NLP) and deep learning neural networks. NLP breaks down speech into interpretable bits, transfers it to a digital format, and analyses the content.

There are two main Automatic Speech Recognition software categories: Directed dialogue conversations and Natural language conversations.

    • Directed Dialogue conversations are machine interfaces that ask you to answer vocally with a single word from a limited selection of options, building their response to your unique request.
    • Natural Language Conversations are more advanced versions of ASR that allow you to employ an open-ended chat structure with them to replicate real discussion.
