Speech Processing in Voice Assistants
Speech Processing in Voice Assistants Speech processing in voice assistants turns sound into action. It starts the moment you speak, with a wake word that signals the device to listen more closely. The audio then travels through noise suppression and beamforming, which reduce background noise and focus on your voice. A speech recognizer converts the sound into text, and a understanding module interprets the meaning. Some assistants send data to the cloud for powerful processing, while others work mostly on the device to protect privacy and respond quickly. Both paths aim for accuracy and speed, yet they balance different limits like network use and device power. ...
