Problems solved by technology
For example, in the case that the speech data uttered by a child contains both English words and Chinese words, the existing scheme needs to use different language recognizers to recognize the speech data of the child, and it is necessary to switch between different language recognition devices during the recognition process. device, it is more complex to implement
[0005] On the other hand, due to the different pronunciation characteristics and pronunciation habits of children of different ages, the general-purpose ASR (Automatic Speech Recognition, Automatic Speech Recognition) technology cannot recognize children's pronunciation normally, and it cannot be accurately scored

Embodiment Construction
[0042] Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0043] The present disclosure proposes a language-independent speech evaluation scheme. Based on the speech evaluation scheme of the present disclosure, without a corresponding language recognizer, it is possible to recognize the speech content of a user (especially a child user) according to the pronunciation similarity, and score according to a simple scoring standard, so that Greatly reduce data costs and algorithm development costs in v...

The invention discloses a voice evaluation and voice recognition method and device, equipment and a storage medium. The method comprises the steps of outputting prompt information, the prompt information being used for prompting a user to emit voice for a test text, the test text comprising one or more characters / words; receiving voice; recognizing the voice based on a character / word recognition model corresponding to the character / word in the test text, the character / word recognition model being used for recognizing whether the voice is matched with the corresponding character / word; and evaluating the voice based on the recognition result. Therefore, when the multilingual mixed to-be-evaluated voice (such as English and Chinese mixed voice) is evaluated, the character / word recognition model can be directly selected, the switching problem of the language recognizer does not need to be considered, and a more accurate recognition result can be obtained by recognizing the character / word level of the to-be-evaluated voice.
Description
technical field [0001] The present disclosure relates to the field of voice interaction, in particular to a voice evaluation and voice recognition method, device, equipment and storage medium. Background technique [0002] As a never-ending topic, education has attracted more and more attention from parents, and various educational institutions for children have emerged in an endless stream. Generally speaking, the cost of offline education is relatively high. Parents need to pick up and drop off their children to class, which takes up a lot of time for parents. Due to traffic, weather and other reasons, it will bring a lot of inconvenience to parents. At the same time, the price of offline education is also relatively high. Therefore, online education is bound to replace offline education and become a mainstream education method. [0003] With the comprehensive advancement of quality education, children's language education is getting more and more attention. How to evalu...
