What Are Speech Models?
Speech models are AI systems designed to process, understand, and generate human speech. These models power speech recognition (converting spoken language to text), text-to-speech synthesis (converting text to natural-sounding speech), and various speech enhancement tasks. They are built on advanced neural network architectures trained on vast datasets of audio and text, enabling them to handle multiple languages, accents, and challenging audio conditions. Speech models are widely used in applications such as voice assistants, transcription services, accessibility tools, customer support automation, and real-time translation systems. The effectiveness of these models is measured through metrics like Word Error Rate (WER), perplexity, recognition accuracy, and their ability to normalize across different speakers and environments.
