The application relates to the technical field of text-to-speech synthesis, in particular to a multi-layer prosody sentence segmentation and tone intonation decoupling control method for Chinese TTS, which comprises the following steps: extracting features related to prosody modeling from a Chinese text to be synthesized to establish a text feature sequence; performing boundary position prediction and correcting the boundary prediction sequence for level consistency; predicting the pause duration of each layer prediction sequence; generating a tone baseline corresponding to the text, calculating a tone residual component corresponding to the sentence layer tone change; generating a residual tone control mark at the end of each tone phrase boundary; and generating a prosody planning sequence. The application cooperatively models the PW, PPH and IPH three-layer prosody boundaries and their pause durations, combines level consistency correction, guarantees the nested consistency of prosody boundaries of different levels, decouples the tone information and sentence tone information in Putonghua, and realizes stable and fine-grained end-of-sentence tone control in the Chinese TTS scenario.

The invention discloses an APK operation compliance verification method and system based on cloud policy control. A client verification module is embedded in an application, environment feature information representing a running environment is collected in the starting and running stages of the application, and the information is encrypted and sent to a cloud verification service; the cloud verification service performs matching analysis on the operation environment based on a pre-configured strategy rule to generate a corresponding verification control instruction; and the client verification module performs runtime control on the display process or process state of the application according to the verification control instruction. The verification logic and the strategy rule are intensively maintained by the cloud and can be dynamically updated, and the client only executes the cloud instruction, so that the effective verification of the compliance use of the APK is realized, and the application is prevented from being used in an unauthorized operation environment.

The application discloses a customer portrait matching positioning method and system, and particularly relates to the technical field of portrait matching positioning. The method performs cleaning and time correction on multi-source behavior data under a unified time base, and constructs behavior time series and label time series. On this basis, a label high-intensity activation interval is identified, and a multi-time scale portrait structure composed of a long-term structural portrait, a life cycle stage portrait and an event portrait is formed. According to the time sensitivity and risk tolerance of a business task, a comprehensive analysis index is calculated to determine whether to introduce time-related dynamic attenuation, and each portrait layer score is obtained and fused according to the weight to generate a comprehensive matching score and output a target customer set. Feedback event sequences are constructed in combination with recommendation, marketing or risk control feedback, and the multi-time scale portrait and the fusion weight are adjusted. The method can distinguish long-term characteristics, stage behavior and short-term events, and improve the accuracy and interpretability of customer portrait matching positioning.
