Content domains are programs that allow the SoundHound server to respond to queries on a certain topic. For example, the "Weather" domain allows Houndify to understand weather queries such as "What's the temperature in San Francisco?" and then ask follow-up questions like, "How about in San Jose?" As a developer, you can choose from a library of over a hundred content domains or we'll help you create custom domains to meet the unique needs of your users.
