Problems solved by technology

Since it is impossible to make a difference from the phonetic notation whether it is connected or not, for example it is (not connected) and it(-)is (connected), where '(-)' is used to indicate the consonant of the previous word and the next The initial vowel of a word is connected, and its phonetic mark is the same as the phoneme pronunciation mark of the acoustic model. For example, whether it is connected or not, its phonetic mark and the phoneme pronunciation mark of the acoustic model are: / ItIz / , so it is difficult to pass Acoustic model discrimination to distinguish continuous reading

Embodiment 1

[0045] figure 1 It is a flow chart of a continuous reading detection method provided by Embodiment 1 of the present disclosure. The method can be executed by a voice detection device, and the voice detection device can be implemented by software and / or hardware. Such as figure 1 As shown, the method specifically includes step S110, step S120 and step S130.

[0046] S110. Obtain the English speech to be evaluated.

[0047] S120. Input the English speech into a logic extension graph for recognition, and the logic extension graph includes a first pronunciation path inserted into a silence model and a second pronunciation path without a silence model inserted.

[0048] Optionally, before step S120, a step of generating a logical extension diagram is also included. Specifically, it may include: obtaining the reference text of the English voice, the reference text includes a mark indicating continuous reading; extracting the mark in the reference text to obtain the normal text, a...

Abstract

The invention provides a continuous reading detection method and device, equipment and a storage medium, and the method comprises the steps: obtaining to-be-evaluated English speech; inputting the English speech into a logic extension diagram for recognition, wherein the logic extension diagram comprises a first pronunciation path in which a mute model is inserted and a second pronunciation path in which the mute model is not inserted; and if no pause representation exists in the recognition result, detecting that the pronunciation of the English speech is continuous reading. By adopting the detection method provided by the embodiment of the invention, whether the English speech is continuously read or not is accurately recognized by judging whether the pause characterization exists or not, and the accuracy is high.

Description

technical field [0001] The present application relates to the field of voice detection, in particular to a continuous reading detection method, device, equipment and storage medium. Background technique [0002] In spoken English, the joint pronunciation of the consonant of the previous word and the initial vowel of the next word is a common phenomenon of context pronunciation synergy. In the oral pronunciation evaluation, it is necessary to assess whether the speaker is connected in the spoken language. At present, the commonly used evaluation method is to recognize the speech information through the acoustic model. Since it is impossible to make a difference from the phonetic notation whether it is connected or not, for example it is (not connected) and it(-)is (connected), where '(-)' is used to indicate the consonant of the previous word and the next The initial vowel of a word is connected, and its phonetic mark is the same as the phoneme pronunciation mark of the aco...
