Methods, systems, and apparatus, including computer programs encoded on computer storage media, for semantic parsing with multiple parsers. One of the methods includes obtaining one or more transcribed prompt n-grams from a speech to text recognizer, providing the transcribed prompt n-grams to a first semantic parser that executes on the user device and accesses a first knowledge base for results responsive to the spoken prompt, providing the transcribed prompt n-grams to a second semantic parser that accesses a second knowledge base for results responsive to the spoken prompt, the first knowledge base including first data not included in the second knowledge base, receiving a result responsive to the spoken prompt from the first semantic parser or the second semantic parser, wherein the result is selected from the knowledge base associated with the semantic parser that provided the result to the user device, and performing an operation based on the result.
