The invention discloses a speech-recognition text classification method and device. The method comprises the steps of respectively collecting training texts and training speeches identical with contents of the training texts for all service classes according to service class types, decoding the training speeches to obtain a work confusion network of the training speeches, extracting text characteristics of the training texts according to the training texts and the work confusion network, training a support vector machine classifier in a set according to the text characteristics, and using the trained support vector machine classifier to classify the texts. The speech-recognition text classification method and device converts a word graph network into the word confusion network suitable for text classification. After confusion words contained in the word confusion network are converted into text characteristics, a support vector machine algorithm is utilized to carry out text classification based on the confusion words. Thus, more accurate classification results can be obtained, and the accuracy of speech-recognition text classification is improved.

The invention provides a speech control method and a speech control device, a balance car control method and a balance car control device, and a balance car, wherein the speech control method is executed by a controller. The method comprises the following steps: receiving speech signals transmitted from a user by virtue of a speech acquisition device; in accordance with a preset rubbish word list, filtering the speech signals, wherein words, which are irrelevant to target identification key words, are saved in the rubbish word list; comparing the filtered speech signals with the target identification key words which are saved in a preset key word list, so that a speech recognition result is generated, wherein the speech recognition result contains control command; researching command codes, which correspond to the control commands, from a preset command code list; and transmitting the command codes to an executor, so that the executor can control the balance car to move in accordance with the speech recognition result. According to the invention, the speech recognition result can be rapidly and accurately acquired, so that the balance car can be controlled in accordance with the result; therefore, efficiency and precision of controlling the balance car can be improved.

The embodiment of the invention provides a voice recognition method and device. The method includes the steps that a first acoustic model is obtained, the first acoustic model represents the mapping relation of input voice signals and a preset state, and the preset state is a basic element of text corresponding to the voice signals; the first voice signal is received; the probability value of the preset state is determined according to the first voice signal and a second acoustic model; the second acoustic model is determined according to a second input voice signal and the first acoustic model, and the first voice signal and the second voice signal are input by the same user; the voice signals include the first voice signal and the second voice signal; the probability value of the preset state corresponding to the first voice signal is decoded as first text according to a preset voice model and a dictionary. By means of the voice recognition method and device, recognition precision of voice input by specific users can be improved.

The invention provides a subtitle generation method and device, equipment and a storage medium. The method comprises the following steps: when receiving a subtitle generation triggering operation forat least one audio track in a target audio and video file, respectively carrying out voice recognition on audio data on each audio track in the at least one audio track to obtain a text fragment corresponding to each audio track; and then, based on the text fragment corresponding to each audio track, generating subtitles of the target audio and video file. Compared with the whole voice recognitionfor the audio data on all the audio tracks, the recognition precision is improved; according to the embodiment of the invention, independent voice recognition is carried out on the audio data on eachaudio track, the influence between the audio tracks is avoided, a more accurate voice recognition result can be obtained, and the accuracy of subtitles generated based on the voice recognition resultis further improved.

The invention relates to an audio data collecting method and equipment used for reducing audio data which is missed during collection and increasing data integrity. The method includes: when a first trigger, a second trigger and a third trigger are used to detect audio signals and the fact that the energy of the audio signal detected by the first trigger is larger than or equal to the triggering threshold of the first trigger is determined, determining that the first trigger is triggered, wherein the triggering threshold of the first trigger is smaller than a first preset threshold; enabling the data channel of a storage so as to use the storage to collect the audio data input into an audio input system.

The invention discloses a speech recognition method and device in a fast application, equipment and a storage medium, which are applied to the field of computers. The method comprises the following steps of acquiring a first speech signal, wherein the first speech signal is a speech signal received by a first fast application in a terminal in a running state; sending the first speech signal to a first speech recognition server, wherein the first speech recognition server is a speech recognition server corresponding to the first fast application, and the speech recognition servers correspondingto the at least two fast applications are different; and receiving the speech recognition result sent by the first speech recognition server. According to the method, the speech signal acquired by the terminal is sent to the speech recognition server specified by the currently running fast application, so that the speech recognition result is more accurate.

The invention relates to an equipment nameplate dual intelligent identification method, a storage medium and a terminal. The method comprises the following steps: S1, obtaining an equipment nameplate image; s2, judging whether the definition of the equipment nameplate image can be subjected to character recognition or not, if yes, recognizing characters in the equipment nameplate image to obtain equipment nameplate content, ending, and if not, executing the step S3; s3, acquiring equipment nameplate voice data; and S4, performing voice recognition on the equipment nameplate voice data to obtain equipment nameplate content, and ending. Compared with the prior art, rapid and accurate identification of the nameplate of the power equipment in a complex power environment is realized.

The invention relates to a pronunciation error detection method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring voice information and standard pronunciation text information corresponding to the voice information; performing voice recognition according to the voice information and the standard pronunciation text information to obtain predicted pronunciation text information corresponding to the voice information; and detecting pronunciation error of the voice information according to the predicted pronunciation text information and the standard pronunciation text information. By adopting the method, the pronunciation error detection accuracy can be improved.
