The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
The inventor considers that the current virtual reality hypnosis guiding technology cannot meet the requirements of users by using fixed and standardized hypnosis voice, and has influence on the hypnosis effect. And if the hypnosis voice is considered to be matched with the hypnosis susceptibility of the user, the expected effect can be realized more quickly and better. On the other hand, the hypnotic susceptible sound object of the user often has no professional hypnotic technical background, and cannot provide a professional and effective hypnotic guiding process for the user. Based on this, the embodiment of the invention provides a virtual reality guided hypnosis voice processing method, which optimizes the hypnosis effect by improving the hypnosis susceptibility of users.
Fig. 1 is a schematic diagram of a virtual reality guided hypnotic speech processing method according to an embodiment of the present invention, as shown in fig. 1, the method may include:
102, carrying out voice analysis on the hypnosis guide language to obtain voice rhythm information of the hypnosis guide language;

and 105, synthesizing the hypnosis voice data with the virtual reality hypnosis scene, and outputting the virtual reality hypnosis guiding voice.
It can be known from the flow shown in fig. 1 that the embodiment of the present invention fully considers that different hypnotic sound characteristics applied to users during the process of guiding hypnosis will have different effects on the hypnotic effect, wherein the users are more easily brought into a specific hypnotic state by the voices of the users susceptible, thereby achieving a better hypnotic effect. Meanwhile, the embodiment of the invention provides a scheme for automatically synthesizing the voice, so that the complexity of field manual recording is avoided, the staged achievement of hypnosis completely generated by a machine is realized, the hypnosis voice with the voice characteristics of the user susceptible can be output, and the user requirements are met. On the other hand, the embodiment of the invention can help people without any hypnosis knowledge background to automatically output hypnosis voice by means of the voice synthesis technology, complete the hypnosis process and help users to better enter the hypnosis state.
In specific implementation, the linguistic data of the user susceptible can be collected in the early stage to establish a hypnosis voice library. The hypnosis voice library stores voice units generated according to the linguistic data input by the user susceptible person. In the embodiment, the corpus can be designed according to the hypnosis voice characteristics to be output, then the user is allowed to record the corpus under the specific requirement, and then the recorded corpus is analyzed and set to establish the required hypnosis voice library. In specific implementation, the corpus recorded by the user susceptible person may be recorded by the user susceptible person according to the hypnotic voice feature. According to the hypnotic voice characteristics, the user is likely to input the corpus under a specific requirement, for example, when recording the corpus, the recorder is required to have consistent volume, slow speed, clear pronunciation, and moderate emotion. The linguistic data input by the user susceptible person can also be input by the user susceptible person under the specified sampling rate and the speech resolution. For example, a recorder is required to record high snr speech at a specific sampling rate and speech resolution, making the corpus more standard.
In addition, in view of the embodiment of the invention, aiming at solving the problem that the hypnotic effect is influenced because the user is not familiar and sensitive to the voice of a hypnotic teacher in the virtual reality hypnotic guiding process by means of the voice synthesis technology, the voice synthesis technology is used for automatically outputting the sound easy to induce the hypnosis of the user in the virtual reality hypnotic guiding process, so that the emotional connection is established with the user in the aspect of language characteristics, and the hypnotic effect is optimized; the dialect of the user or the voice of the trusted person of the user can more easily enable the user to enter a specific hypnotic state, so that a better hypnotic effect is achieved, and therefore the linguistic data input by the susceptible person of the user can be input by the dialect of the susceptible person of the user and/or can be input by the susceptible person of the user by using a personalized language. Therefore, the requirement of the user is met by outputting the hypnosis voice with local characteristics and individuation. Since the key point of the embodiment of the invention for introducing the speech synthesis technology is to output the speech of the user with a hypnotic sensibility, the recorder of the previous corpus is suggested to be selected specifically.
After the user susceptible person inputs the linguistic data, the hypnosis voice library is established and updated in real time according to the linguistic data input by the user susceptible person. In the process of establishing and updating the hypnosis voice library, the linguistic data can be split in the hypnosis voice library by using a hidden Markov model to construct a voice unit.
When virtual reality guidance hypnosis voice needs to be output, text analysis needs to be carried out on the hypnosis guidance words to obtain text level information of the hypnosis guidance words; and carrying out voice analysis on the hypnosis guide words to obtain voice rhythm information of the hypnosis guide words.

In a specific embodiment, when text analysis and voice layer prosody analysis of the hypnotic guide are performed, text analysis may be performed on the hypnotic guide of the text version, and the analysis may be performed on the language layer, the grammar layer, and the semantic layer, respectively, to obtain the hierarchical information of the hypnotic guide, that is, the hierarchical relationship of phrases, sentences, and the like; for example, in combination with the virtual reality hypnosis feature, the hypnosis guide words negotiated with professional hypnotics mainly include progressive relaxation guide, hypnosis scene guide and the like, and the information such as words, phrases, sentences and the like in the hypnosis guide words is obtained by analyzing the grammatical and semantic meanings of the text information. Then, prosody analysis is performed on the basis of the voice layer of the hypnotic guide, for example, information such as tone, intonation, loudness, and the like of the voice corresponding to the hypnotic guide is analyzed to obtain prosody information of the voice layer.
After the text level information and the voice rhythm information of the hypnosis guide language are obtained, corresponding voice units are searched from the hypnosis voice library according to the text level information and the voice rhythm information of the hypnosis guide language, and then the searched voice units are synthesized into hypnosis voice data. In specific implementation, the hidden markov model can be used for selecting, splicing and synthesizing the searched voice units. And correspondingly synthesizing the voice units extracted from the hypnosis voice library to obtain the required voice data, namely the hypnosis voice data which is easy to be sensed by the user. In a specific example, the hypnotic guidance is output in a gentle and emotional manner, so it is necessary to control the speed and impart emotion to the hypnotic voice during the voice synthesis process.
And finally, synthesizing the hypnosis voice data with the virtual reality hypnosis scene, and outputting the virtual reality hypnosis guiding voice. For example, the synthesized hypnosis voice data can be adjusted, optimized and finally shaped under the guidance of a professional hypnotizer, and then the synthesized hypnosis voice data is guided into a virtual reality hypnosis scene to output virtual reality hypnosis guiding voice.
