All too often people make snap judgments based on how you speak. Some AI systems are also learning to be prejudiced against some dialects. And as language-based AI systems become ever more common, some minorities may automatically be discriminated against by machines, warn researchers studying the issue. Anyone with a strong or unusual accent may know what it's like to have trouble being understood by Siri or Alexa. This is because voice-recognition systems use natural-language technology to parse the contents of speech, and it often relies on algorithms that have been trained with example data.
