Here’s a good read about voice technology from the Engineering VP for Google Assistant. Key point: people expect conversations. Which is why understanding people’s goals for a conversation is a critical part of conversational design.
Quoting Scott Huffman:
When people start using voice assistants, we often see very simple commands. But very quickly, expectations go up in terms of complex dialogue. We might see “weather Chicago” typed in Search, whereas with the Assistant we see much longer and more conversational queries like “what’s the weather today in Chicago at 3pm.” On average, Assistant queries are 200 times more conversational than Search.
Scott’s other points about voice and conversation are also worth considering. Check it out here:
