I noticed Multi-Crew Experience is advertising support for L1011, 757 & 767. The idea is appealing, although I would feel silly talking to my computer. (Maybe not so much in my Alexa / Siri world now.) Just wondering what your experience has been. I've seen rave reviews for it with other products.

I  bought MCE a long  time ago, but it's not installed at  the moment. I also have Voice Attack (installed) for other games, but it can also worjk with FSX/SE/P3D. Years ago, I used to use Voice Buddy for both Flight Sim, and games. As a person  with a disability, these are extremely helpful to my flight sim/gaming experience, but I still feel quite silly calling out commands to  the microphone (it's not so bad if I don't use headphones though).

Almost all Captain Sim planes are supported (only CS 130 has limited support).
Many more complex planes from other vendors also fully integrated.
Currently, the only voice based crew simulation that works with MSFS 2020.

Upgrade to MSFS 2020 support is free for registered users.

I am using MCE with the CS L1011. I've added some bells and whistles (literally) and have to say it's very good. But it requires spending some time getting used to it. With a crew of three, it is great. The documentation is voluminous, but if I could make a suggestion to them it would be to organize for more intuitive use, and to include some bits of information I don't think is there at all (such as "don't modify the checklist with anything but default Notebook, and if you do, here's how"). However, the support is prompt and helpful (and I've needed a lot). Still working out a kink or two, probably introduced by me.
