Abstract: A method including in response to voice information, acquiring a response object to which corresponding voice information is registered and which occupies an interactive medium; and informing the response object to respond to the voice information. The technical solution enables an operating system to automatically determine a response object responding to voice information triggered by a user from numerous response objects in view of voice information registered at each response object and the occupation of interactive media by each response object. The technical solution removes the restriction that a user must speak a wakening phrase to activate a required response object each time before speaking voice information. Thus, a user only needs to speak short voice information that shows the intention for use thereof during a process of using a certain response object, thereby improving the convenience of a user performing voice interaction.

Abstract: Methods, systems, and devices for techniques for initializing memory error correction are described. A memory system may perform operations relating to writing data to multiple memory cells belonging to one or more rows of the memory system in response to a single write command.

The memory system may activate a set of rows indicated by the row group address. In response to a write command (e.g., a row group write command), the memory system may write data in a respective memory cell of each row indicated by the row group address. For example, each memory cell to be written may correspond to a column address included in the write command. The memory system may write a same logic state to each memory cell.
