Are any voice assistants making any money?
The problem with voice assistants at the moment is the same as command line tools.
You have to know what specific prompts work and don’t work etc. I often see my parents make simple queries like “turn off the white lights and turn on the night lights” only to get the response that it can only do one thing at a time.
There will be a future where this gets more and more sophisticated. But in the meantime, it’s not surprising it’s losing money.
A customer of mine has a product based on DragonNaturallySpeaking that medical doctors use for dictation. They are doing a brisk business. It's all software. No fancy hardware. For this use case, it's almost flawless. And way faster than typing. The only commands you give are related to the recording -- stop/start/playback-type commands. Not sure how sophisticated it gets beyond that. But the speech-to-text technology is pretty damn good now.
