How Voice Recognition Works
By Probo AI
Voice recognition technology analyzes spoken language, converting audio input into written text.
01.
The process begins with acoustic modelling, breaking down the audio signal into smaller units, such as phonemes.
02.
Machine learning algorithms, like CNNs and RNNs, learn acoustic patterns from vast training data to identify speech sounds accurately.
03.
Language modeling understands the context and grammar of spoken words, predicting likely word sequences based on NLP techniques.
04.
The lexicon and vocabulary component matches spoken words to written representations, using a dictionary of word pronunciations.
05.
Probability distributions from both acoustic and language models are combined to select the most likely word sequence as the recognized text.
06.
Voice recognition is an iterative process, refining results with statistical models to make probabilistic decisions.
07.
Variations in accents are addressed by training models on diverse datasets to adapt to different speech patterns.
08.
Advanced noise-cancellation algorithms reduce background noise impact on speech recognition accuracy.
09.
Disambiguating homophones requires context and language models to infer the intended word in a sentence.
10
Voice recognition is evolving with transformer-based models, such as BERT, for improved language understanding.
11
The integration of voice recognition with NLU enables context-aware and conversational interactions for more intuitive user experiences.
