Hi Katy! The Q70T does not feature anti glare technology. Check out the Q80T for anti-reflection technology optimal for a bright room. Soundbars are a great addition to any TV. To improve voice clarity, you want a soundbar with a center channel, like the HW-Q60T, to separate voices from the background making it easy to hear the dialog. Check out the following links from Best Buy for the optimal TV for a bright room, and a great soundbar to pair with it for dialog clarity. https://www.bestbuy.com/site/samsung-55-class-qled-q80t-series-4k-uhd-tv-smart-led-with-hdr/6402394.p?skuId=6402394
