AI systems for generating, understanding, and manipulating human speech. This includes text-to-speech (TTS), speech-to-text (STT/ASR), voice cloning, real-time voice translation, emotion detection in speech, and conversational voice agents. The field has advanced to the point where AI-generated speech is often indistinguishable from human speech.
Why it matters
Voice is the most natural human interface, and AI is finally making it programmable. Voice AI powers everything from customer service bots to audiobook narration to real-time meeting transcription. The ethical implications of voice cloning — consent, identity, fraud — make this one of the most sensitive areas in AI.
