Understanding Intelligent Speech Recognition Technology

Intelligent speech recognition converts spoken audio to text using a pipeline of feature extraction, acoustic and language modeling, where deep neural networks—especially CNN, LSTM, and hybrid CLDNN architectures—drive high accuracy, enabling mobile voice input, call‑center transcription, legal record keeping, and Tencent Cloud ASR’s 97% Mandarin accuracy with speaker separation and on‑premises deployment.
