Embodiment 1

[0030] The embodiment of the present invention provides a method for synthesizing speech in Chinese teaching, figure 1 is the flowchart of the method, such as figure 1 As shown, the method includes:

[0031] Step 101, acquiring language learner's voice and a plurality of standard teacher's voices;

[0032] Step 102, select the standard teacher's voice closest to the language learner's voice from a plurality of standard teacher's voices according to the voice parameters, wherein the voice parameters include: acoustic parameters, pitch, rhythm information;

[0033] Step 103, synthesize the tone teaching voice according to the closest standard teacher's voice and the language learner's voice.

[0034] As can be seen from the above description, by synthesizing the tone teaching voice with the selected standard teacher voice and the language learner's voice, since the synthesized tone teaching voice is similar to the language learner's own voice, it will be easier for language le...

Embodiment 2

[0070] An embodiment of the present invention also provides a speech synthesis device for teaching Chinese, which is preferably used to implement the method in the first embodiment above. Figure 5 is the block diagram of the device, such as Figure 5 As shown, the device includes:

[0071] Voice acquiring unit 1, used to acquire language learner's voice and a plurality of standard teacher's voices;

[0072] The nearest standard teacher's voice selection unit 2 is used to select the standard teacher's voice closest to the language learner's voice from a plurality of standard teacher's voices according to the voice parameters, wherein the voice parameters include: acoustic parameters, pitch, rhythm information;

[0073] The tone-teaching speech synthesis unit 3 is used for synthesizing the tone-teaching speech according to the closest standard teacher's speech and language learner's speech.

[0074] As can be seen from the above description, the tone teaching speech synthesis...

Abstract

The invention provides a method and a device for voice synthesis for Chinese teaching. The method includes steps of acquiring pronunciation of a language learner and a plurality of standard pronunciations of teachers; selecting the standard pronunciation, which is closest to that of the learner, of the corresponding teacher from the standard pronunciations of the teachers according to pronunciation parameters including an acoustics parameter, pitch and rhythm information; and synthetizing tone teaching pronunciations based on the pronunciation, which is closest to that of the learner, of the corresponding teacher and the pronunciation of the learner. By the aid of the method and the device, the language learner can learn pronunciation more easily, so that good help can be provided for the Chinese language learner.

Description

technical field [0001] The invention relates to the field of speech signal processing, in particular to a speech synthesis method and device for teaching Chinese. Background technique [0002] One of the great difficulties that foreigners face when learning Chinese is the learning of Chinese tones, because the changes of Chinese tones are much more complicated than the stress. In order to solve the problem of learning Chinese tones, some scholars have proposed various targeted teaching methods of tones, but often only trained teachers of Chinese as a foreign language can master this teaching method, and students have limited means of self-learning. [0003] Since the 1990s, the research on computer-assisted language learning (CALL) has made great progress, and speech processing technology has been widely used in computer-assisted language learning (CALL) systems, among which speech recognition is widely used in the learning of learners. Pronunciation level detection and eva...
