Despite its compact 82M‑parameter size, Kokoro matches the quality of larger TTS models while being faster and more cost‑efficient; it supports multiple languages, voice blending, and a CLI tool for batch processing, though users note occasional mispronunciation of single‑word homographs when speaking isolated words.

The article explains that the EU's Chat Control 1.0, a temporary derogation from 2021 allowing voluntary scanning of messages for child sexual abuse material, has been revived and expanded in Chat Control 2.0, which proposes mandatory client‑side scanning of encrypted communications to detect CSAM and grooming content. These proposals threaten end‑to‑end encryption by requiring either on‑device scanning or privileged decryption, which could enable mass surveillance without judicial oversight and affect the privacy of all EU citizens. Chat Control 1.0 relied on hash‑based image matching performed by service providers, whereas Chat Control 2.0 extends to text‑based grooming detection and mandates scanning on users’ devices before encryption.

Starting July 7, 2024, the European Union’s General Safety Regulation requires every new car and van sold in the EU to be equipped with an infrared driver‑monitoring camera to detect distraction and drowsiness. The rule aims to cut road‑accident fatalities caused by inattention, while pushing automakers to adopt AI‑based cabin sensing and raising privacy and cost considerations for consumers. The system uses an infrared camera and AI algorithms to track eye gaze, head pose and eye‑closure in real time, works day and night, and can be integrated with existing advanced driver‑assistance systems.
