Speech Recognition

Speech recognition (speech recognition) is the technology called Automatic Speech Recognition (ASR) in English literature, which automatically converts voice speech into written text. The process is technically transformed into a numerical representation such as specogram before the raw sound wave, then this acoustic signal of a model to fundems (the smallest volumes of the tongue), which works in the form of mapping words. Early-term systems are based on statistical methods such as Hidden Markov Models, today’s systems use deep nerve networks, especially Transformer-based architectures that are trained to end-to-end, so background noise can be dealt with much better at different accents and speech speed.

OpenAI’s Whisper model has significantly improved the space by providing high accuracy in numerous languages and noisy real world conditions. Speech recognition; Siri is the basic technology of real-time subtitle systems for transcription tools, voice-operating vehicle and home systems and hearing impaired users, such as Google Assistant and Alexa. The field often creates two basic components of end-to-end voice AI assistants, along with audio (TTS) technology.
