In addition, the intelligent terminal can also communicate with the cloud server, after the intelligent terminal acquires the characteristic information of the off-line intelligent equipment, if the corpus corresponding to the model off-line intelligent equipment is not found in the pre-stored corpus set, a data request is carried out on the cloud server, and the corpus corresponding to the model off-line intelligent equipment is downloaded to the corpus set for calling.
Each corpus includes a number of speech entries, each speech entry having file identification information that is unique relative to other speech entries in the corpus. The file identification information may specifically include a model name, a model ID, a command word ID, an original corpus content, an original corpus length, a new corpus content, a new corpus length, and the like.
Certainly, when the intelligent terminal establishes communication with the offline intelligent device, the feature information sent by the offline intelligent device further includes data content specific to the offline intelligent device, so as to uniquely identify the offline intelligent device. The intelligent terminal calls the corpus corresponding to the off-line intelligent equipment according to the characteristic information, forms a list and displays the list on an interactive interface of the intelligent terminal, and a user can select the voice items needing to be modified to edit.
Since the corpus generally includes a response corpus and a control corpus, before the user selects a specific speech item, the user also needs to select to modify the content in the response corpus or the control corpus.
For example, after selecting the response corpus, the user enters a response speech item list, selects one of the speech items, and enters an editing interface, and at this time, the user can select the following manner to edit the speech item:
① modifying the text content of the voice entry, and generating corresponding audio content by the application program according to the text content;
② the new audio content is generated directly by means of sound recording.
Of course, in the ① method, before generating the corresponding audio content, the characteristics of the audio content may be adjusted, such as modifying and editing the tone, pitch, and timbre of the human voice in the audio, or even selecting a specific human voice for the synthesis of the audio content.
And finally forming a basic file as an audio file by modifying the response corpus, transmitting the audio file to the offline intelligent equipment for replacement, and when the response voice item is triggered, playing the audio file by the offline intelligent equipment.
For another example, after selecting the control corpus, the user enters the control voice entry list, selects one of the voice entries, and enters the editing interface, and at this time, the user can select the following mode to edit the voice entry:
① modifying the text content of the voice entry;
② the audio content is generated by recording and the semantic recognition is carried out on the audio content by the application program to generate new character content.
And when the acquired voice is consistent with semantic content contained in the text file, the offline intelligent device triggers corresponding action.
The formed audio content or text content is a new voice entry, the voice entry is transmitted to the offline intelligent device by the intelligent terminal, and the language database on the intelligent terminal is synchronously updated during transmission, namely, the new voice entry is replaced with the voice entry in the original language database on the intelligent terminal, so that the consistency between the language database on the intelligent terminal and the language database in the voice control system in the corresponding offline intelligent device is ensured.
In addition, in the regenerated voice entry, the file identification information of the original voice entry corresponding to the regenerated voice entry is provided, after the offline intelligent device receives the new voice entry, the voice control system firstly verifies the validity of the voice entry, determines that the file format of the voice entry is the required format and simultaneously contains valid data content, then extracts the file identification information attached to the voice entry, determines the storage position of the original voice entry corresponding to the newly generated voice entry according to the file identification information, then erases the data content of the storage position, writes the content of the received voice entry into the storage position, returns the corresponding result, and displays the result on the intelligent terminal, thereby completing the modification and replacement of the original voice entry in the voice control system of the offline device.
In the processing process of the voice control system, it needs to determine whether the model name and the model ID attached to the voice entry are correct, then determine whether the corresponding command word ID and the original corpus information exist, and then call the corresponding API interface managed by the database to replace the corpus.
According to the offline intelligent equipment corpus modification method provided by the invention, the intelligent terminal is introduced, the intelligent terminal is used for establishing communication with the offline intelligent equipment, the content of a voice control system in the offline intelligent terminal is modified, a user can modify a control corpus or a response corpus in the offline intelligent equipment by himself, and the personalized requirements of the user are effectively met.
