Plug an Echo Dot into the Connect's analog input. That will give you voice control of Spotify, Amazon Music, TuneIn and a couple of other services right now, with the ability to play on any or all your Sonos devices throughout the house, until Alexa is fully integrated into Sonos (Google and Apple voice control coming, too, per the CEO). It will also provide Bluetooth, in case you don't use one of several podcast services already in Sonos, or the Audible service in Dot (and soon, Sonos itself), or the podcasts saved to your phone/tablet/PC/NAS, which the Sonos app will play if they're not DRM protected, or any of the millions on Soundcloud, etc. Way too many sources, lol. If there's a service that hasn't already integrated with Sonos (it's the only multiroom system that has all the big players already), point them to Sonos' partner API, which is open to all services, and simple to integrate. They also have a casting API, which Spotify and Google currently support, Pandora soon will, and any other service provider is welcome to use. Not a huge demand for podcasts through a high quality music system (I don't recall ever finding a need), so a cheap bluetooth speakers will work, as well.
