The Roku Streambar is adequate for dialogue-centric TV shows and podcasts. It's a 2.0 bar, meaning you don't get a discrete center channel to improve vocal reproduction. Despite that, its mids are pretty balanced, so it can still reproduce vocals with some clarity, making it easy to follow the action on screen. There's an adjustable Speech Clarity feature available to make dialogue more crisp, as well as an adjustable Volume Mode to quiet loud commercials.
