Google supports over 40 languages and is available in a wide range of regional dialects, with better handling of non-English queries compared to Alexa.
Alexa supports multiple languages too, including Hindi, Spanish, French, and more. However, it usually requires you to switch language settings manually. Regional support for localized content, such as traffic, news, and weather, is strong in both, but Google’s access to real-time Google Search data gives it a noticeable edge in certain regions.
Accuracy in Commands and Follow-Ups
Google Nest is the leader when it comes to understanding complex questions and follow-up commands. Its contextual awareness allows it to handle chained queries like:
“What’s the weather in New york?”
“What about London?”
“How about this weekend?”
Google understands the progression without needing the full sentence again — making conversations feel more natural and fluid.
Alexa, while accurate in direct commands, sometimes struggles with follow-ups unless they’re part of a pre-set Routine. However, its command recognition accuracy has improved with Alexa’s language model upgrades, especially for smart home control.
