摘要： A method for detecting a keyword, applied to a terminal, includes: extracting a speech eigenvector of a speech signal; obtaining, according to the speech eigenvector, a posterior probability of each target character being a key character in any keyword in an acquisition time period of the speech signal; obtaining confidences of at least two target character combinations according to the posterior probability of each target character; and determining that the speech signal includes the keyword upon determining that all the confidences of the at least two target character combinations meet a preset condition. The target character is a character in the speech signal whose pronunciation matches a pronunciation of the key character. Each target character combination includes at least one target character, and a confidence of a target character combination represents a probability of the target character combination being the keyword or a part of the keyword.

摘要： An association logic that associates a non-text message type with specified information is established. The association logic includes at least identification of the non-text message type, allowing a message type in line with the association logic to be identified by the identification. A first message is monitored. A first identification corresponding to the first message is obtained by analysing the first message. It is detected, according to the first identification, whether the first message is of the message type in line with the association logic. It is determined that the first message supports display of the specified information when it is detected that the first message is of the message type in line with the association logic.
