The voice annoyed me too. But then I had a thought that you will be able to customize it to whichever sex, whatever age, accent, and even personality you want in the future.

Not sure if utopia or dystopia but either way the future looks to be an inexorable slide into an atomized, entirely curated existence for each individual plugged into the matrix, and even for those who try to opt out, any interaction with government or corporations is likely to be mediated by some AI trying to tailor the interaction to best engage you.

It should be able to automatically or manually adapt the level of expression or totally different mood, depending on the context of the conversation. Otherwise yeah it would be annoying if it is all the time like that. A demo is a demo. We will have to test it and see.
