Quick answer: Build speech-to-text systems — Whisper, Conformer, Indic-language ASR.
Speech Recognition, or Automatic Speech Recognition (ASR), converts spoken audio into written text. It's the technology behind voice assistants, transcription services, and accessibility tools. ASR systems use deep learning models like Whisper (OpenAI's multilingual model), Conformer architectures, and specialized Indic-language models to process acoustic features and linguistic patterns. You'll work with audio preprocessing, acoustic modeling, language modeling, and decoding strategies. ASR powers real-world applications: customer support chatbots that understand voice queries, medical transcription systems for doctors, accessibility features for people with disabilities, and voice-controlled IoT devices in smart homes.
