Problems solved by technology

It can be seen that the existing embedded speech synthesis technology has at least the following disadvantages: first, the storage of sound clips on the embedded device still takes up a lot of storage space, and second, the voice spliced ​​out is not natural enough.

[0057] The embodiment of the present invention provides an embedded speech synthesis method, such as figure 1 shown, including:

[0058] Step S1, obtaining the text information to be played of the embedded device;

[0059] Wherein, the text information to be played is text information to be synthesized into speech, and the text information to be played may be text information directly input by the user through the embedded device, or may be converted by the user through voice interaction with the embedded device. text information, etc.

[0060] Step S2, obtaining a plurality of linguistic feature trees corresponding to the text information to be played from the database of the embedded device;

[0061] Step S3, merging the plurality of linguistic feature trees into one target linguistic feature tree according to the text ranking of the text information to be played;

[0062] Step S4, synthesizing the target linguistic feature tree into speech.

[0063] Among them, the acoust...

Abstract

The present invention relates to an embedded speech synthesis method, device, controller and medium. The method includes acquiring text information to be played of an embedded device; acquiring the text information corresponding to the text information to be played from a database of the embedded device. multiple linguistic feature trees; merging the multiple linguistic feature trees into a target linguistic feature tree according to the text sorting of the text information to be played; synthesizing the target linguistic feature tree into speech. The invention reduces the required storage space on the embedded device and improves the quality of the embedded speech synthesis.

Description

technical field [0001] The invention relates to the technical field of speech processing, in particular to an embedded speech synthesis method, device, controller and medium. Background technique [0002] Embedded device synthesis does not require arbitrary text synthesis in many scenarios, and usually only needs to do text synthesis in related fields. The computing resources and storage resources of embedded systems are much less than those in the cloud. With a small amount of resources, text conversion must be compromised. The quality of voice (also known as speech synthesis, TTS for short in English) can be completely offline. It can be seen that, in the prior art, it is still relatively difficult to implement a set of high-quality TTS on an embedded device without a network. [0003] The speech synthesis engine can usually be divided into a front-end engine and a back-end engine. The front-end can be understood as mapping characters to phonemes and other artificial ling...
