At least in North America, voice interaction in public with virtual assistants hasn’t yet been adopted en masse. It’s rare to catch someone in a coffee shop talking to Siri or Google Assistant.
It seems that here, we still want to keep the things we tell our phone private. Changing an appointment, creating a reminder, or texting a friend back, seem like things we don’t want others to hear us say, even as inconsequential as these things are. In Asia, this isn’t the case. People are dictating into WhatsApp or WeChat with abandon.
It seems companies like Google, Nuance, or Amazon might do well in developing models for speech recognition for whispering in English — at least until it becomes socially normal to talk to our devices in public here.
