AI-powered translation tool helps eliminate language barriers
Walmart has created a real-time translation feature, available in 44 languages, to facilitate multi-lingual conversations among associates and customers. The tool enables conversations in both text-to-text and speech-to-speech formats and is enhanced with Walmart-specific knowledge. For example, if the customer asked for something more specific — like “Where’s Great Value Orange Juice?” — the tool would recognize “Great Value” as a Walmart house brand and keep it properly translated or referenced.
