[0061] figure 1 It is a flowchart of a prosody prediction method provided in the first embodiment of the present application. This embodiment is applicable to the situation of accurate prosody prediction for Chinese-English mixed text. The method can be executed by a prosody prediction device, and the device can be realized by software and / or hardware. see figure 1 , the prosody prediction method provided in this embodiment includes:

[0062] S110. Segment the Chinese-English mixed text to be predicted to obtain Chinese text and English text.

[0063] Among them, the Chinese-English mixed text is a text that includes both Chinese and English.

[0064] The Chinese text is a text including only Chinese.

[0065] The English text is a text including English only.

[0066] The quantity of both the Chinese text and the English text can be one, two or more.

[0067] S120. Determine word vectors of characters in the Chinese text and word vectors of words in the English text.

[0078] figure 2 It is a flow chart of a prosody prediction method provided in the second embodiment of the present application. This embodiment is an optional solution proposed on the basis of the foregoing embodiments. see figure 2 , the prosody prediction method provided in this embodiment includes:

[0079] S210. Segment the Chinese-English mixed text to be predicted to obtain Chinese text and English text.

[0080] S220. Determine word vectors of characters in the Chinese text and word vectors of words in the English text.

[0081] Among them, the word vector of the word in the English text is determined, including:

[0082] Segment words in English text into sequences of letters;

[0083] determining letter vectors for letters in said sequence of letters;

[0084] According to the determined letter vector, a word vector representing the semantics of the word is extracted.

[0085] Specifically, according to the determined letter vector, the word vector representi...

Abstract

Embodiments of the invention disclose a rhythm prediction method and device, equipment and a medium, and relate to the field of data processing, in particular to a voice synthesis technology. The method comprises the following steps of segmenting a Chinese and English mixed text to be predicted to obtain a Chinese text and an English text; determining character vectors of characters in the Chinesetext and word vectors of words in the English text; and determining a rhythm prediction result of the Chinese and English mixed text according to the determined character vectors and word vectors. According to the rhythm prediction method and device, the equipment and the medium, the rhythm prediction accuracy of the Chinese and English mixed text is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of data processing, and in particular to speech synthesis technology. Specifically, this embodiment provides a prosody prediction method, device, device and medium. Background technique [0002] Before speech synthesis, it is necessary to predict the prosody of the speech text. [0003] Existing prosody prediction methods include: predicting the text content to be predicted by a machine learning method according to a pre-trained prediction model, and obtaining the corresponding pause prediction result of the text content, wherein the pause prediction result can include pause position, pause type (can include long pause, short pause, etc.) and a probability value corresponding to the type of pause. [0004] The above scheme has the following defects: [0005] The text content to be predicted does not distinguish between languages. When the text content includes both Chinese and English, t...
