Spoken language pronunciation evaluation method and device, electronic equipment and storage medium

Abstract

The invention provides a spoken language pronunciation evaluation method and device, electronic equipment and a storage medium. The spoken language pronunciation evaluation method comprises the stepsof obtaining an audio frame sequence corresponding to a to-be-evaluated voice segment and a phoneme sequence corresponding to the to-be-evaluated voice segment, determining a phoneme pronunciation state basic label corresponding to each audio frame, adjusting the phoneme pronunciation state basic label corresponding to each audio frame to obtain a phoneme pronunciation state final label corresponding to each audio frame, according to the final label of the phoneme pronunciation state, determining the energy proportion of the target word in the to-be-evaluated voice segment in the to-be-evaluated voice segment, and obtaining a spoken language pronunciation evaluation result according to the energy proportion. The energy proportion of the target word in the to-be-evaluated voice segment canreflect whether the spoken reading phenomenon exists or not, so that the spoken reading phenomenon is detected according to the energy proportion, the spoken language pronunciation evaluation result obtained according to the energy proportion can reflect the influence of the spoken reading phenomenon on the spoken language pronunciation evaluation result, and the accuracy of the spoken language pronunciation evaluation result is improved.

Description

technical field [0001] The present application relates to the technical field of speech recognition, and more specifically, relates to a spoken pronunciation evaluation method, device, electronic equipment and storage medium. Background technique [0002] With the current economic development and cultural exchanges, the requirements for individuals' foreign language ability are getting higher and higher. In the process of learning a foreign language, how to improve the oral ability of a foreign language is an urgent problem to be solved at present. With the development of artificial intelligence, speech recognition technology has been applied to oral pronunciation practice. At present, there are many oral pronunciation evaluation software for evaluating oral pronunciation. practice. [0003] However, there are currently some users who read randomly in the oral pronunciation evaluation software. These random readings seriously affect the accuracy of the oral pronunciation e...

Problems solved by technology

[0003] However, there are currently some users who read randomly in the oral pronunciation evaluation software. These random readings seriously affect the accuracy of the oral pronunciation evaluation results, and the current oral pronunciation evaluation methods cannot accurately detect these random readings. Based on Therefore, how to effectively detect the phenomenon of random reading and improve the accuracy of the spoken pronunciation evaluation results is a technical problem that needs to be solved at present.
