Speech Processing: From Voice Assistants to Transcripts

Speech Processing: From Voice Assistants to Transcripts Speech processing turns spoken language into text and actions. It powers voice assistants, call centers, captions, and searchable transcripts. The goal is clear, usable language across devices and situations. The pipeline has several stages. First, capture and pre-processing: a microphone records sound, and software reduces noise and normalizes levels. Next, feature extraction: the audio is turned into compact data that a computer can study. Then the acoustic model links those features to sounds or phonemes. A language model helps predict word sequences so the output sounds natural. Finally, a decoder builds sentences with punctuation, and a post-processing step may flag uncertain parts for review. ...

Accessible AI: Designing for Everyone

Accessible AI: Designing for Everyone Accessible AI is not a luxury; it’s a baseline for trustworthy technology. When AI systems generate text, recommendations, or images, they should be usable by people with different abilities, languages, and devices. Designing for accessibility from the start helps everyone: better outcomes, fewer misunderstandings, and wider reach. Clear goals matter. Start with users in mind and define what success looks like for them. Use plain language, predictable behavior, and clear feedback when the system is unsure. When the AI makes a mistake, offer a simple explanation and an easy way to correct it. ...

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. ...
