Well there are three Siri tweaks that I'm aware of that have the toggle features. The most popular tweak is AssistantExtensions which allows you to use siri to enable and disable toggles (but requires sbsettings). AE also has several other built in features like Chatbot, extension customizer, direct YouTube searches etc. I'd recommend that because it allows voice commands of sbsettings but has a bunch of other uses. PLUS, it's developed in such a way that other developers can creat custom Siri tweaks which hook into AE. In cydia, go to Sections, then Addons (Siri) and you'll find a bunch of Siri tweaks; some require AE others do not.
