Speech Processing for Voice Interfaces
Speech Processing for Voice Interfaces Voice interfaces rely on speech processing to turn sound into action. A well designed system understands you clearly, responds quickly, and keeps your data safe. This article explains the core parts and offers practical tips for builders. Understanding the pipeline The journey starts with capturing audio. Noise and echoes can hide words, so good systems clean and align the signal. Next comes feature extraction, where sound is turned into numbers the computer can read, often as spectrograms or MFCCs. A neural acoustic model then predicts the most likely words. A language model helps choose sentences that fit the context. Finally, the decoder converts the guess into text or a command. ...
