There’s been a lot of talk this week about new Twitter features, mostly disappearing tweets. But Twitter also announced Tuesday that it’s planning voice-only chat rooms called Spaces where you talk instead of type. Earlier this summer, Twitter experimented with letting people send audio-only tweets, but didn’t allow for captioning those tweets, so they were inaccessible to the deaf community. Twitter put that feature on pause and has now created two new teams — one to make Twitter a more accessible place to work and another to vet product ideas for accessibility. And, according to Twitter, accessibility has been “top of mind when developing Spaces.” “Marketplace Tech” host Molly Wood speaks with Dalana Brand, vice president and head of inclusion and diversity at Twitter.
