Designing a chatbot: male, female or gender neutral?

Picture a virtual assistant that helps find directions, schedules appointments or plays music, and the soothing yet robotic sound of a female voice likely comes to mind. From Apple's Siri to Amazon's Alexa, a majority of the world's most popular virtual assistants have female personas. But that's starting to change as a growing number of consumers -- and companies -- turn to digital assistants. Some developers are going against the grain, creating chatbots and messaging apps that no longer conform to one gender and challenging a tradition of female digital assistants that some say display submissive personalities. Making virtual assistants female by default can be bad for business and perpetuate stereotypes, these chatbot developers say, so they're offering more options to consumers.
