Speech Recognition in AI (Artificial Intelligence)

Speech recognition in artificial intelligence (AI) involves converting spoken language into text or commands. The process typically includes audio preprocessing, feature extraction, and machine learning. Common techniques like Hidden Markov Models (HMMs), deep learning (e.g., using recurrent neural networks or convolutional neural networks), and transformer models (e.g., BERT) are used for speech recognition. Libraries such as Google's Speech Recognition API, Microsoft Azure Speech Services, and Mozilla DeepSpeech provide APIs and tools for implementing speech recognition systems. Applications include virtual assistants (e.g., Siri, Alexa), transcription services, and hands-free device control. Challenges include handling accents, noise, and speaker variations for robust performance.
