A method and system for achieving emotional text to speech. The method includes: receiving text data; generating emotion tag for the text data by a rhythm piece; and achieving TTS to the text data corresponding to the emotion tag, where the emotion tags are expressed as a set of emotion vectors; where each emotion vector includes a plurality of emotion scores given based on a plurality of emotion categories. A system for the same includes: a text data receiving module; an emotion tag generating module; and a TTS module for achieving TTS, wherein the emotion tag is expressed as a set of emotion vectors; and wherein emotion vector includes a plurality of emotion scores given based on a plurality of emotion categories.

Voice based biometric authentication method, apparatus (system), and computer program product. Provided is voice verification solution with a high accuracy rate that can prevent cheating via recording. The method includes: transmitting to the user a question prompt requiring the user to speak out a voice segment and an answer to a dynamic question, the voice segment having a corresponding text dependent speaker verification model enrolled before the authentication; segmenting, in response to receiving the voice answer, the voice segment part and the dynamic question answer part out from the voice answer; and verifying boundary smoothness between the voice segment and the answer to the dynamic question within the voice answer. With this method, whether a voice answer relates to cheating via recording is determined according to the degree of smoothness at a detected boundary. The apparatus and computer program product carry out the steps of the above-mentioned method.
