A text-to-speech synthesis method, an electronic device, and a computer-readable storage medium are provided. The method includes: obtaining prosodic pause features of an input text by performing a prosodic pause prediction processing on the input text, and dividing the input text into a plurality of prosodic phrases according to the prosodic pause features; synthesizing short sentence audios according to the prosodic phrases by performing a streamed speech synthesis processing on each of the prosodic phrases in the input text in a manner of asynchronous processing of a thread pool; and performing an audio playback operation of the input text according to the short sentence audios corresponding to the first prosodic phrase of the input text, in response to synthesizing the short sentence audio corresponding to the first prosodic phrase of the input text.

Provided are a method and apparatus for controlling an electronic cigarette, and an electronic cigarette. When a trigger signal is received, the electronic cigarette is initiated, a heating temperature of a heat generating sheet of the electronic cigarette is controlled to be a first temperature, and the heat generating sheet enters a low-temperature heating state; when it is determined that no cartridge exists in a cigarette pocket of the electronic cigarette, the heating temperature of the heat generating sheet is controlled to be maintained at the first temperature which cannot combust a flammable substance, thereby when the electronic cigarette is carried, avoiding safety hazards of a fire brought by an unintentional trigger of an initiation switch in case a flammable substance is brought into contact with the heating element of the electronic cigarette, and improving the usage safety of the electronic cigarette.

Embodiments of the present invention provide a multiple description audio coding and decoding method, apparatus, and system. The audio coding method includes: dividing residual signals indicating current audio signal information into multiple frequency band parts having different frequencies; respectively coding the multiple frequency band parts by using multiple description coding (MDC) methods with different speech quality; and combining each of description signal parts that are generated after coding is performed by using different MDC methods to form multiple description bit streams of the residual signals. According to the present invention, multiple description coding and decoding methods with different speech quality are used for different frequency bands, which reduces the bit rate of multiple description coding and decoding, improves the effect of multiple description coding and decoding, and hence enhances the quality of audio transmission.
