Speech Processing: From Recognition to Synthesis Speech processing covers how machines understand spoken language and how they speak back. It includes turning sound into text, and turning text into sound. Modern systems usually combine several steps, but recently many end-to-end models blur the line between recognition and generation. The result is faster, more natural interactions with devices, apps, and services. Automatic Speech Recognition, or ASR, converts audio into written text. Key parts are feature extraction, acoustic modeling, and language modeling. Traditional systems used separate components, but today neural networks enable end-to-end approaches. These models learn from large data sets and can run in real time on powerful servers or, with smaller devices, locally. Important topics include noise robustness, speaker variation, and multilingual support. ...

Speech Recognition and Synthesis: Talking to Machines Speech recognition and speech synthesis are two simple ideas that power modern talking machines. Recognition turns spoken words into text. Synthesis turns text into spoken words. Together, they let devices listen, understand, and respond. They are common in phones, computers, and smart speakers, and they can help people with different needs. Recognition works in steps. The microphone captures sound, and software splits it into small parts. It then guesses which words fit best, using patterns learned from many voices and languages. This makes systems adaptable to different accents, but noise, fast talk, or rare terms can still cause mistakes. Good tools update with user feedback and try to improve over time. ...
