I think that's the reason. Bing is not popular but gets used by a lot of IoT/personal assistant services and therefore the share should be higher than with Google. Curious about Baidu though. With some languages it's much easier to speak them than using your keyboard, so people adopt this feature sooner. Apart from that it would be interesting how search will increase if Messenger/Whatsapp would integrate that into their product. I feel like voice is used way more in messaging and some people only live in messengers anyway, so it could definitely help adoption.
