🎙️ AI for Speech-to-Text

📘 Definition

Speech-to-Text (STT), also known as automatic speech recognition (ASR), is the technology that converts spoken language into written text.

AI for Speech-to-Text leverages machine learning and deep neural networks to accurately transcribe audio speech in real-time or from recordings.

🔍 Detailed Description

AI-powered Speech-to-Text systems analyze audio signals, recognize phonemes, words, and sentences, and convert them into text using models like Hidden Markov Models (HMM), recurrent neural networks (RNN), and transformers.

These systems handle variations in accents, speech speed, background noise, and multiple languages to provide highly accurate transcriptions for diverse applications.
